I don't get it...

I have a AMD-64 3000 with a gig of memory, 6600GT, all pretty good stuff.

Whenever I run the limited sharpen I get all these small stutters and my CPU (through ffdshow OSD) is at 100%.

I d/led the scripts and added the calls in ffdshow. ALL I have turned on in ffdshow is limited sharpen!

ZP, nvidia 185, avisynth 2.5 and this script:

# LimitedSharpen() ( a modded version, 29 Oct 2005 )
#
# A multi-purpose sharpener by Didée
#

I've tried it with dscaler 5 too, still stutters.

The only way I can stop the stutter is to drop limited sharpen down below 1.0 in ffdshow. I don't like that because it's too soft.

Any ideas? I REALLY like the way it looks at 1.25 but I really HATE the stutter.

BTW, I have WinDVD7 and DNM looks awesome. But as BBQ said, sometimes movies look "fake" like watching a video and not film.

Thanks...
I've had just about every problem known to man with this crap since I started it, but I think I've finally gotten a pretty good handle on it. I'll assume that you are using Zoomplayer, and the Nvidia Purevideo Decoder.

With my particular system (AMD64 4000+), overlay mode is the performance king. I can do up to 1.2 SS in Limited sharpen, 3dDenoising, and resizing up to 720p at a max of 80% CPU usage. Knocking off the SS brings it down to an average of 40% usage. To me, the picture quality is the worst, though. It still looks good, but once you use one of the VMR modes, you won't want to use it.

The VMR modes are a mixed bag. Renderless performs the worst, regardless of whether I'm using the "exclusive" mode or not. Perhaps future optimizations within Zoomplayer will fix this, but for now they should not be considered options if you want to do anything other than resizing.

The VMR9 Windowed and Windowless options, as well as VMR7, will handle denoising, limitedsharpen with no SS, and resizing with about 80% CPU usage. This is acceptable to me because I feel the image quality you get from using the VMR9 modes makes up for the loss in SS. After tweaking the colors a bit from the Nvidia decoder, the image quality is in my opinion stunning.

Using Nvidia Post Processing in ANY mode results in a pretty nasty speed hit, so avoid using it.

Make sure you are using the versions on the ffdshowGuides (http://free.hostdepartment.com/f/ffdshowGuides/index.html)

Avisynth 2.56 and fast limitedsharpen and the lastest masktoools 2.0 should give you a bump in speed.

On Trimension;

In WinDVD 7 like WinDVD 6 that "fake" look is due in part to WinDVD's Overlay settings thus that"fake" look is not nearly as prevalent when used in ZP or GAM.

The third image does appear a little soft but more natural, I noticed that sometimes the sharpening can make images kind of 3dish almost pop off the screen but the TrimensionDNM seem to keep most of the sharpening yet de-3dishes the image.

You can always crank up the strength parameter or try supersampling in Limitedsharpen to make it more crisp. However you need to see it in ZP or GAM first to get a real visual judgement of what it does.

Now if we can only find a way to use WinDVD 7 "enhanced" version of TrimensionDNM that uses less processing power to work so we can re-size or kick in Supersamplging easier it would even be better. :D

Ah, that reminds me. For joeuser2, these are the avisynth DLL versions I'm using:

Warpsharp YV12 - only difference from regular Warpsharp is that it is YV12 native, and it adds the Xsharpen function (which I don't use). Saves you a manual colorspace conversion step if you notice the colors are a little off with the standard Warpsharp.

Masktools 2.0 alpha 11 - Latest version

RemoveGrain package - SSE2 versions. Definitely a bit faster than the standard builds, as long as your AMD64 core revision supports the SSE2 extensions. The SSE3 version crashes, even though my processor allegedly supports the extensions.

For FFDshow, I'm using the latest daily build from Milan's site, which seem to be pretty quick and stable. I plan on giving the now ancient "Andy" SSE2 builds a try to see if they will help reduce the Denoising and Lacznos resizing performance penalites, but have my doubts that they will be of any benefit to my CPU due to the Intel compiler he uses.

Socio,

I went back to your web site (BTW, thanks for making it) and used your links and got fresh versions of a few things.

BBQ,

I used SSE3 and it works. I'll grab Warpsharp YV12 and see if that makes things better.

BTW, you Hawaiian? I believe Kai means sea/ocean if my memory is correct. Lived there for 4 years.

Well, I reloaded everything from a fresh d/l and at least limitedsharpen is working. I have it on 1.3, 1.3 and it looks good. I still get some stutters when I turn on resize, lancoz 2 and 3 stutters at 1280x720. But the picture looks pretty good with just LS so I'm pretty happy.

Thanks for the tips. And thanks to those who made, keep current, and contributed to that limitedsharpen web site. I couldn't have done it without it.

Oh My Freaking Goodness!! Tonight has been the biggest PITA trying to update to all the new plug-ins, etc. And 99% of the time, it was my dumb ass that kept messing things up - and it would take me 30 mins per mistake just to figure out what I did wrong. My wife is making me sleep in the guest room tonight because, well, I got a "little" angry.

The good news is that everything works now, but I am too tired to hook it up to my PJ. Tomorrow night will be fun.

Anyway, the new updates have put me just under the ceiling - I can Resize now @ 1280x720 without any stutters - before I would get an occassional stutter that drove me through the roof.

I was curious as to the strength most people use. 40 seems good to my eyes, but I will have put it up against Avia's sharpness patterns to see what is going on - I don't see any visible ringing or halos.

Excellent thread, Socio - and others who have helped.

How much strength to use depend on what projector you use and how 3D-like you prefer the movie to look.
I use a Sony 1271 CRT projector and use strength 100-160 on it. That gives me almost as much 3D as HiDef 1080i material do without to much artifacts. I suspect though that the CRT is getting soft on me... because of the many hours the unit has on it now.
A month ago I tested a JVC HX2 and a Hitachi TX200 and with them I used much lower values (lowest on the JVC) around 30-50.
I've never needed any noise reduction or grain removal of any kind though.

Socio,

Great work on the entire Avisynth LimitedSharpen pre-processing thread :)

Before I go any further here are my HTPC specs:

Claritas 390M Stands Unique HTPC Case
P4 3Ghz Northwood 800FSB
Zalman CNPS7000B CPU Cooler
Asus P4800-VM with onboard SPDIF out
2x 512mb 400mhz Crucial DDR
ATI 9600XT Passive gfx card
Samsung Spinpoint 2x 250GB SATA HDD
Seasonic 350 PSU
MCE 2005 SP2
MCE Catalyst 5.4 video driver
TheaterTek 2.2

I have been using ffdshow with Blur & NR, Resize 1280 x 720 Lanczos2, Luma sharpen .60 for playback on all movie materials for over a year now and have been happy so far.

I recently stumbled across your thread about a week ago have tried using limitedsharpen with ffdshow on all movie playback using the exact settings on your recent guide and following the installing as instructed.

Using your reccomended limitedsharpen settings (but reducing the strength from 40 to 30), I have found that limitedsharpen gives the sharpest picure with the least about of ringing/halos and artifacts on my Hitachi TX100 1280 x 720 PJ but there is one very slight annoying drawback though and that is I can see a slightly more shimmering effect (aliasing?) on diagnals that wasn't present before.

Cpu usage with the above settings is around 50-60%. If I up the super sampling on both y & X from 1.0 to even 1.1, my cpu just maxes out. However that does seem to reduce the aliasing effect.

Is there any way I can optimize my HTPC further so that I can achieve a higher super sampling than 1.0 without my cpu maxing out?

How can I get hold of LimitedSharpenFaster as there doesn't appear to be a link for it on your guide?

Thanks

For those who has enough CPU juice....

Try running Resize before Avisynth.

I do a 2xlanczos2 resize before my avisynth limitedsharpen script. It takes alot more CPU power but produces a cleaner image. At least for me.... ;)

N3W813,

I've just seen you latest ffdshow settings on the 'official ffdshow settings' thread and your HTPC specs seems very similar to mine (3ghz) with your gfx card being much better.

Base on our similar HTPC specs, how on earth are you able to set your super sampling to 1.3 on your limited sharpen settings and what CPU usage do you get from those settings?

My CPU maxes out at just super sampling 1.1 :confused:

I have all the settings set up as per the instructions on you webste, I'm using the 11/29 ffdshow build with the preset "dvd" call script you provide too. Any ideas what the problem is???

Sorry, forgot to state....when I do resize before avisynth, my limitedsharpend is at 1.0 and 1.0.

When I use LS before resize, I then use 1.3 1.3 for the settings.

Sorry for the confusion. :P

Has anyone encountered terminal errors with TT/ffdshow/avisynth? I'm a long time ffdsow and TT user but I admit avisyth is another magnitude of complication. I have scoured the treads and have seen lots of issues but no one reporting "TT has encountered a serious error and needs to close". Once this happens, the only fix I have found so far is to uninstall everything, including TT and start from scratch. I REALLY want to give that thing a try and any help is greatly appreciated.

Vidcan

12-29-05, 12:52 AM

Vidcan,

It can't find the file. Double check that you named it the same as what you have in ffdshow. BTW, why did you add that .vdf? Just name it "avsfilter.avs"

Come to think of it...I use limited sharpen and that is ALL I call from ffdshow. I have a "limitedsharpen.avs" file in the avisynth directory and I call it in ffdshow.

tk2001,

I have the same problem. I have no idea HOW these people are doing all this stuff! I can't go any higher than 1.1 without 100% CPU and forget about adding resize too! I'm running limitedsharpenfast too.

I just have these settings in ffdshow:

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=3,strength=40)

I'm not calling avsfilter.vdf.avs anywhere.
After playing around with ZP a little bit I was able to get it working only after I turned off VMR renderless mode. Even then it gives me the avsfilter error twice which I press ok to and then it starts to play. Also, when I set smode to 4 it crashes ZP, smode 3 and 2 worked fine and I think 1 would too.

The only way the avisynth route would work for me is with VMR renderless mode because on Nvidia 6800 graphics cards when you go to 1080i resolutions you will get stutter even with like 50% cpu useage. BTW this is on Andy's 08 2004 ffdshow build.

Any ideas???

N3W813,

What is your CPU usage when you have your super-sampling set @ 1.3 1.3 and do you have HT enabled?

Also are you using LimitedSharpenFaster and if so can you post a link to it?

Thanks

Btw any tips on how you are able to acheive ss 1.3 1.3 using ur 3ghz P4 without maxing out the CPU would be much appreciated among those trying to trying to acheive the same goal using similar set-ups. :)

I'm not quite in your CPU class - all I have is a 2.8 Northwood and no OC - but that sounds pretty outlandish to me - both the 1.3 stuff before and even more with 1.1 stuff AFTER resize. (?!) Maybe without any kind of denoiser running? But even then, it sounds more like what I would expect from a FAR more powerful CPU. Getting up around the 4G level, I could imagine running something like that. Getting that kind of performance underneath that CPU level sounds more like an urban myth to me.

With a good denoiser running and a Lanczos4 resize to 1280X720 I have to leave my settings at 1.0. Even doing that I have to turn up my CPU and system fans - otherwise the CPU goes into overheat protection after about an hour of DVD - something my son can't even do playing running Madden 2005 at SXGA for two hours straight.

(I've also got to say that I can't notice the difference between a 1.0 and a 1.3 on my Benq 6200 pj, though that's only native XGA.)

Your mileage may vary, of course ... I'm certainly not trying to accuse anybody of faking it.

No faking here! Got my P4 530J (3.0Gig) processor and I turn Hyperthread on (in fact, with my HTPC, everthing runs slow without it on).
-Video Card: PCI-E 6600 128Mb (77.72 Driver) Desktop @ 1080i
-Display is a NEC 6pg Xtra Crt
-DVD Player is TheaterTek 2.2.1 using VMR9 Fullscreen Exclusive mode

Now using FFDshow-20051129 (Daily Build) as followed (only need a good sharpener for my CRT so no denoise used):
-Avisynth
Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen_Faster.avs")
SetMTMode(2,0)
LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=4,strength=70)
-Resize @ 1280x720
Settings = Lanczos @ 2.00 / Luma Sharpen @ .30

Currently, my CPU is running about 96% (48% w/Hyperthread) and I see no stuttering. About a month ago, I was using FFDshow-20050303 and could only use LimitedSharpen(ss_x=1.2,ss_y=1.2,Smode=4,strength=45) but switched to the 20051129 build and to my surprise, got about an extra 5% speed boost to allow me to get to "ss_x=1.3,ss_y=1.3". By increasing the sampling size I was able to increase the strength without seeing any adverse affects you would get with over-sharpening (ringing, jaggies, moire etc).

Also found (for me) that using SetMTMode(2,0) instead of MT("LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=4,strength=70)", avisynthTS=true) was faster (about 3%) but others say MT() works better - the only way to know is to just try it...

Thanks for the tip. I changed from blur and NR , then limitedsharpen @ 40, then lanczos 4 resize to 1920 X 1080 to moving the resize before the limitedsharpen. Looks a lot better. Difficult to put into words, but the picture jumps off the screen. I am able to push the ss to 1.7 with an AMD x2 4.4 without problems.

Thanks a lot Socio for the guide and everything!

I am having some issues with getting good DVD playback. I have a brand new build:

AMD Opteron dual core running at 2820mzh each
2 gig DDR524 ram
eVGA 6600GT

Here are my settings:

multithread version of AviSynth
latest version of zoomplayerpro
Dscaler5 audio/video decoding
ffdshow with:

Blur and NR (seems to have little effect turned on or off):
Gradual Dnoise 30
Dnoise3d Luma 0.39 Chroma 1.55 timing 3.88

AviSynth:
MT("LimitedSharpen(ss_x=1.0,ss_y=1.0,Smode=4,strength=50,oversho ot=7)",avisynthTS=true)

Resize with Lanczos2
If I push the resolution beyond 1.5x, it kills the frame-rate. Shouldn't this CPU crunch filters like gangbusters?? Maybe it's my 6600gt? Oh well. Any advice to get a better picture? Thank-you!!

EDIT - Task Manager shows one core maxing out and one core idling.... hmm
Why won't it use both?

This is strange... I did this same thing yesterday, and had stuttering problems running AVISynth BEFORE resize. But when I switched the order around and run AVISynth AFTER resize (which should be even more CPU intensive) I get no stutters and I am also able to max out settings even further.

This seems wrong... I wonder what gives? Not that I"m complaining!

muzz

01-02-06, 01:21 PM

I tried Avi AFTER resize, and it maxes out my cpu.

I remember when I used Blur(I dont normally use blur, as i have a CRT) in front of Resize it actually lowered cpu usage before.....
I may try that again.

MT("hqdn3d(2)
LimitedSharpen(ss_x=1.0,ss_y=1.0,Smode=3,strength=40,oversho ot=7)",avisynthTS=true)

I follow this up with a ffdshow/lanczos4 resize X 2 and use approx 25% of 1 core and 80% of the other (athlon64 3800 X2)

I'm very happy with the results. I find the PQ much better than that from just ffdshow with the settings from the htpcnew.com tutorial. I just wish now I had a few more Mhz to tweak the settings.

okay, I tried the different MT commands, and my second core is still doing NOTHING. It's sitting still and I only get 50% CPU usage no matter what I try. Here're my settings:

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

SetMTmode (2)

LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=3,strength=60)
ColorMatrix()
Lanczos4Resize(2596, 1104)

It works, but I need a little more speed to pull off that resize. I'm sure I'd be fine if only my other CPU would kick in. What's going on?

Dude your not using the mt mode. You have to use this:

MT("LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=3,strength=60).ColorM atrix().Lanczos4Resize(2596, 1104)",avisynthTS=true)

Also make sure you have the mt.dll loaded.

NeezyDeezy,
If you need alittle more CPU try using FFdshow RESIZE instead of Lanczos4Resize() within Avisynth.

I just have these settings in ffdshow:

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=3,strength=40)

I'm not calling avsfilter.vdf.avs anywhere.
After playing around with ZP a little bit I was able to get it working only after I turned off VMR renderless mode. Even then it gives me the avsfilter error twice which I press ok to and then it starts to play. Also, when I set smode to 4 it crashes ZP, smode 3 and 2 worked fine and I think 1 would too.

The only way the avisynth route would work for me is with VMR renderless mode because on Nvidia 6800 graphics cards when you go to 1080i resolutions you will get stutter even with like 50% cpu useage. BTW this is on Andy's 08 2004 ffdshow build.

Any ideas???

In addition to the updates tetsuo55 mentioned there is a newer version of the LimitedSharpen script that makes better use of the Limitedsuport.dll . It does require the latest limitedsupport.dll that tetsuo55 posted which I also included in the .rar

FYI: WarpSharp is only required if you try/use Smode=2 if you so do not use Smode=2 and have no intention to try it then you can just leave Warpsharp out of the mix.

NeezyDeezy

01-08-06, 02:21 AM

I'm certain I'm using the multithreaded version of avisynth. I've tried several, actually, even the 2.60 beta. CPU core 1 gets to 100%, CPU core 0 stays at 1 to 2%. It just won't work. I've tried setmtmode in every configuration too... from (0) to (5, 5). When I use the MT(" command it keeps giving me a string of errors having to do with width and height changing that refuses to be resolved. I guess I'll just have to wait the 3 more days till I can post on Doom9 forums... that 5 day rule is such garbage. Were they having any real problem with spammers even???

Li On

01-08-06, 03:20 AM

NeezyDeezy, just a guess, you use super-sampling at "ss_x=1.3,ss_y=1.3" and LimitedSharpen will do some Resize during the sharpen process. That may cause the MT function to give the error as it's doc stated it won't work with process that change BOTH height/width.

You may try to use the default "ss_x=1.0,ss_y=1.0" to test first.

regards,

Li On

NeezyDeezy

01-08-06, 04:27 AM

I tried it just as you said, and I get "MT: function changed the height! Try vertical split=true"

when I try verticalsplit=true, it says MT does not have a named argument verticalsplit

When I can get the HT(" command to work, the second core does work ie it is using both, but it's not worth it if I can't do anything else in avisynth.

Li On

01-08-06, 04:34 AM

You also need to drop that "Lanczos4Resize(2596, 1104)". Resize don't work in MT.

regards,

Li On

NeezyDeezy

01-08-06, 04:40 AM

Yeah, that's the problem. I didn't know resize didn't work in MT. Yeah, now that I think about it that would be very hard if not impossible to program a resize in a way that has 2 separate threads. Maybe sometime in the future.

In the meantime this gives the best performance:

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

MT("LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=3,strength=60).ColorM atrix()")

Lanczos4Resize(2000, 848)

or close

CPU usage still never goes above 57% no matter what the settings... which is discouraging.

Delete the SSE3 removegrain dll from your plugin folder it does not work correctly, use the RemovegrainS dll that seems to work for most everyone. Also the RemoveGrain SSE2 should work as well but only if your processor supports SSE2.

I copied the LimitedSharpenfaster as a file called LimitedSharpenfaster.avs in the avisynth plug-in directory. Is it depended on the original script, or should I have called it .avsi?

EDIT: oops I forgot to change the call to LimitedSharpenFaster instead of LimitedSharpen.

Guys, there is a new mask tools 2.0 beta 18. On the limited sharpen page it says the new mask tools incorporates limited sharpen now and there is no need for limited support??? Socio do you know how to set up the new version of mask tools correctly? The new mask tools also comes with limitedsharpenfaster.dll but I didn't see the limited support file there.
Thanks

Just replace the mt_masktools.dll and limitedsharpenfaster.avs in your plugins directory with the new ones, and you can delete the limitedsupport.dll if you'd like. Since the function is included in masktools.

01-18-06, 07:15 AM

N3W813 I removed limitedsupport.dll and the old limitedsharpen.avs files. The new mask tools comes with a file called limitedsharpenfaster.avsi which I renamed limitedsharpen.avs because that was what it was named from Socio's website and what my calls are listed as in ffdshow. I now get an error message saying that limitedsharpen is not found in line 4.

It's OK, if you explicitely call import:

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

In case of using original script's extention (*.avsi), the script will be loaded automatically so you would not need import and string

Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpen.avs")

may be safely removed from ffdshow.

The new function in mask tools is called "LimitedSharpenFaster". Instead

LimitedSharpen(ss_x=1.3,ss_y=1.3,Smode=4,strength=70)

you should use

LimitedSharpenFaster(ss_x=1.3,ss_y=1.3,Smode=4,strength=70)

in ffdshow settings.

As the last remark I would suggest to remove string

converttoyv12()

as redundant. For faster process you need to feed YV12 format to LimitedSharpen by setting input format for AviSynth filter in ffdshow. LimitedSharpen outputs the same format you feed in (at least in earlier versions, I have not taken closer look on LimitedSharpenFaster), so extra conversion call is just useless burning of CPU cycles.

Is there any way to run ffdshow with LimitedSharpen, yet still take advantage of DXVA MPEG-2 decoding in my Nvidia PureVideo decoder? The problem I'm having is that the moment I insert ffdshow into the graph by assigning it to handle all supported uncompressed formats, the entire DVD playback graph becomes software-only, no DXVA is used and the peformance suffers greatly.

Say, I'm just curious:

When I use Avisynth in my ffdshow chain, it takes DVDs about 30 seconds to load. When I take it out, they load in seconds. This isn't the end of the world, but it isn't exactly fantastic either. IS this normal? I don't think I've seen anyone else commenting on this.

Partly, I'm wonderin whether my load times are so slow because of all the filters I have sitting in my Avisynth plugin directory. They just sort of accumulate and I can hardly remember which ones are for what, so I just leave them there ...

Or are there any other tips to improve load times?

Peace,

Howdy All,

Im noticing a lot of people using calls like the following:

Setmtmode(2)

MT("LimitedSharpen(ss_x=1.5,ss_y=1.5,Smode=3,strength=30",avisynthTS=true)

Quoting from Socio's site:

There are two good ways to use this in your call, the first just utilizes the multithreading Avisynth.dll and you would use it like this keeping the "SetMTMode(2)" above any other call functions :

and

The other way which utilizes both the plugin and the dll and is my preferred method would be used like this keeping the MT(" portion infront of other call functions and keeping the ",avisynthTS=true) at the end of all the call functions :

So when using the avisynthts=true at the end, does the setmtmode(x,x) actually do anything, or any harm???

Cheers,
Bitey

01-20-06, 12:07 AM

I tried the new MaskTool 2a18 & LimitedSharpenFaster.avsi (autoloading now from plugin - ie I no longer Import the LSF script) and things just keep getting better. Reading my taskmgr, it looks like I'm getting about 5% more CPU than I did with Masktool 2a17 on my PC (3.0Gig w/HT on). I'm happy to report I do not see any visible horizontal faint lines in the middle so I'm not sure why it's happening to others; maybe its caused by diff versions of FFdshow (I'm using Daily build 20051129 from Sourceforge), a combo of filters used (I only RESIZE 2x then use Avisynth w/LimitedSharpenfaster) or MT() itself (try using SetMTMode() instead of MT()).

Mr Bitey,
I've experimented with MT() & SetMTMode() and for some reason the SetMTMode() parm give me better CPU utilization on my machine - others have reported just the opposite, of course YMMV. I did remember reading the developer of MT saying since MT does it's own multithreading it wouldn't take advantage of SetMTMode(). Everytime a new version of these things come out, I usually check the CPU % to see which is better. By the way, with MT ver05, I did find I had to remove the 'avisynthTS=true' parm as I believe N3W813 reported.

jidelite

mikesusangray

01-20-06, 02:21 AM

OK, I decided to try updating to a newer MaskTools set and the new MT - partly in hope of speeding up load times a little, mostly just to keep up with things. Since I updated to the v.2a18 I've started getting an error, however:

There is no function named "mt_average."

It seems to crop up in 76 or 77 of the new LimitedSharpenFaster.avs.

I'm guessing that I haven't rounded up a filter or two that I need - or else that I need a different version of some limitedsupport (though I thought I didn't need this any more).

Does anyone have an idea how to get this sorted out again?

* fixed : bug with asm and width lower than 64
* fixed : doesn't prepend (0, 0) pixel to the forms helpers
* added : "min/max" mode to mt_edge. The edge value is local max - local min ( taken on a
3x3 square ).
* added : mt_lutf : a frame lut, see the description above
* added : mt_luts : a spatial lut, see the description above

Changed from alpha 19 to alpha 20 :
* fixed : huge bug preventing most filters from working

Changed from alpha 20 to alpha 21 :
* fixed : two & three input clips filters where requesting wrong frames
leading to ghost artefacts.

52% (720x480, 24fps, 2.35:1)

Removing resize in ffdshow and increasing ss_x and ss_y to 1.7
73% (720x480, 30fps, 1.78:1) **CPU graph shows 1 at 70% and 1 at 80%**

It looks like resize, that is not multi-threaded, takes up too many cycles on one of the cpu cores. If someone can develop a resize filter for avisynth that can be used in MT, or better yet, a MT version of ffdshow, then we can really use limitedsharpen to its full potential.

Hope this will help the people that are on the fence deciding to jump to the dual core camp. :D

P.S. May test PAL (720x576) sources in the near future, will post results if I do. :)

With the latest mask tools, except a18 which works fine, the image is really blurred. I tried mask tools a21 and a22 and both blur the image very noticeably. There is some kind of bug there.

Im pretty sure I saw it was fixed with a23 - give it a shot... there are some other issues with MT05 avisynth.dll and any version past a18 of masktools..

N3W813,
Just out of curiousity, what kind of CPU % do you get with your P4 3.0GHz HT if you did:
Ffdshow -
Resize [2x, Lanczos2, no luma or chroma sharpen]
Avisynth [Add ffdshow video source, YV12]

jidelite

I don't quite remember....I think it was ~60% with no dropped frames. :o I didn't really like how the image looked if avisynth ran after resize.

FYI for everybody...All of this is subjective....my display (GWIII) is probably different from yours. I like my image a little over sharpened (more of a HD look). Some people like it sharpened a little to keep that soft film look. There isn't one configuration for everybody, adjust and test settings to your liking.

Well I tried the WinDVD DNM tweak on Zoomplayer. That is the freakiest thing I have ever seen! It looks 3D. I don't know if that is a good thing or not yet, but I was getting some pixelation around the edges during movement. Anyone else that has tried this seen that as well? If you do not have the pixelation with the DNM tweak, how about posting your versions and settings.

another new masktools release

http://manao4.free.fr/masktools-v2.0a24.zip

this one should have a fix for the problems people have been reporting, also this version should be a little bit faster

fingers crossed

changelog:

Changed from alpha 21 to alpha 22 :
* added : "med"/"median" mode to luts/lutf
* changed : luts doesn't necessarily consider the center pixel
* changed back : forms helpers prepends (0, 0).
* changed : forms helpers now have a bool "zero" parameter, defaulted to true
* added : bool "luma" parameter to mt_merge, which makes it use the luma mask for
all three planes, and which forces chroma modes to "process" ( u=v=3 )

Changed from alpha 22 to alpha 23 :
* fix & speed up : median mode, thanks to tsp's insightfull remark. Note to self : think
less like a mathematician, and more like a programmer. Simpler, faster & not bugged.

Changed from alpha 23 to alpha 24 :
* fixed : issues with MT.dll ( thanks tsp, Boulder, vanessam and all those who suffered the bug )
* fixed : check for YV12 colorspace, and report an error if it isn't.
* speed up : median mode for luts ( once again, thanks to tsp )

Volley,
I used the limitedsharpen (not faster) and very satisfied with the result, using zoomplayer, DVD motion is smooth on a intel 3.3GHz (HT enabled with MT) with resize to 1360x768. Tried the WinDVD DNM tweak on Zoomplayer, the picture is more even more 3D, but the motion becomes not smooth, very obovious during motion an dlooks like the frame per sec is not able to match the 24. Strangely enough, when turned on the ffdshow OSD, the frame per per sec looks above 24 most of the time (sometimes 30+) and cpu most of the time < 50% but once a while 100%. I like the DNM picture and but the motion impact makes the film unwatchable. Any one has idea too? ffdshow on 2006Dec version.

01-30-06, 09:00 AM

Just a side note, Socio's site had said that you create a regkey of zplayer under videodec and then useDNM=1. This did not work for me and I just got the normal WinDVD codec. I found another guide that said to put the useDNM in the videodec and set it to 1. That did work. Like I said, very freaky effect. But even with ffdshow off on my dual core 3.2GHz I get stuttering. The pasteurization change helped, but I still have stuttering and some odd artifacts around edges. Like I said, I am still not sure I like the effect. It is kind of like looking at the film through your kids viewmaster! Very 3d, but almost disturbingly so. Try out Mr. and Mrs. Smith with it. Will probably go back to denoise, resize, then sharpen on NVIDIA codecs.

adamy

01-30-06, 11:48 AM

thanks Volley. the UseDMN seems work for me by updating the zplayer section, and I got a 3d picture but stuttering. This is strange as cpu% and frame rate seem to be fine, just stuttering is obvious. I give up (you have 3.2 dual core) and turn it back to the my original windvd 7 codecs.

No - it shouldn't be necessary.

What are your system specs and what do your ffdshow and avisynth settings look like?

In my experience, the whole thing is just VERY finicky. It tends to take a long time and a lot of grief before everything works correctly together. Keep on testing - and try to explain your situation as clearly as possible. Who knows, it might even all work out ...

02-06-06, 04:12 PM

Aaargh.

Becuase of a number of problems (none related to this thread) I had to reformat and setup XP sp2 again from scratch.

The system is a 2.8 Northwood with HT, not overclocked, with 512 MB Ram. I was and am still using ZP 4.51 (VMR9 exclusive), the latest avisynth and MT version 5.

Before I had LimitedSharpenFaster (the "18a" version) running with these settings:

SetMTmode(2)
MT("hqdn3d(2)
LimitedSharpenFaster(ss_x=1,ss_y=1,Smode=4,strength=40)")

This was followed by a Lanczos resize in ffdshow - 2 tap, to 1280/720. I had high CPU usage - maybe 65% overall, - one side nearly topped, the other about halfway. The picture was terrific.

Now that I've rebuilt, I'm getting a weird phenomenon. Either I can do a ffdshow resize OR I can run a limitedsharpenfaster + denoise combo - but as soon as I try to use both the CPU bonks. No matter how much I tweak the resize - including a drop to lanczos 1 or even bicubic - the CPU hits the roof. Even with no denoise at all, I still can't make it work. Putting the resize in the avisynth box instead of doing int through ffdshow makes no difference.

I've checked my versions of MT and MaskTools till I was cross-eyed, I've tried several recent version of ffdshow (settling on Milan Vutka's Nov 3, 2005 version) - I just can't solve it.

But here's the Weirdest Thing of All: every once and a while - usually after extensive testing - the thing just seems to settle in and work fine - but, at the very latest, as soon as I reboot the computer, it starts all over again.*

Can anyone give me a hint about how to troubleshoot here? I've prett much run into a wall.

P.S. BREAKING NEWS: FOR EXAMPLE, RIGHT NOW, THE *#% THING HAS SUDDENLY STARTED WORKING AGAIN. I was testing the situation as I wrote this post and getting the exact problems I described above. Just before hitting send, I added the line "hqdn3d(2)" to my avisynth box and tried again. All of a sudden, CPU usage in Task Manager dropped back a bit and ffdshow reported an FPS up around 31 - up from about 12 before.

So, I think, is it an issue of denoising before I sharpen? Seems plausible. I remove the denoise to check. Nope: CPU usage drops even further and fps is even more stable. I try PAL and NTSC material. I try SageTV and Zoom Player. It all works now. But WHY?!

What on earth is going on here??

Peace,

Mike

I dunno. I don't think so, because the whole thing is working nicely this morning without it ... (I am aware that hqdn3d is a YV12 filter - so maybe something weird did happen there.)

I'll keep fiddling and updating - if I can isolate what is happening, this may be of help to some other poor saps out there ...

BTW, I'm using MaskTools a26 now. Before I reformatted Iwas getting that horizontal streak; now it's gone. Why do computers have to be as incomprehensible as everything else in life??

I have actually gone back to LimitedSharpenFaster at x=1.0 and y=1.0, Strength=70 (RESIZE @ 2x/Lanczos 2 before AVISynth) and I don't really see any jaggies. Of course YMMV...

mikesusangray,

Im with you on the 'fiddly' nature of this beast :-)

Im running a P4 3.0 at ~3.5 and in order to have smooth pans everytime im running really low settings:

hqnd3d(1), no supersampling, smode4 and shapening 30.. I then lan2 or lan4 to 1776x1000.. I get very very smooth motion all the time using this method.. If I up hqdn3d to 2, or increase sharpening to even 40 then i get occasional stutters that are repeatable on specific scenes - ie. it stutters in the same place in the same scene but is smooth most of the time..

This is using mt5 and masktools a26.. I thaught I ran a higher setting using a18 and mt4 and a lower overclock - but I might be mistaken (ive been tuning my overclock so its stable for encoding too)...

Cheers,
Bitey

jidelite

I was trying to go for eliminating the jaggies with 1.0 and strength of 100.
The reason I did this was because I recently popped a DVD into my RP82 connected through component to watch Temple of Doom. Granted the DVD is old and the video wasn't that great, it was very sharp on my RP-82 compared to LimitedSharpenFaster(). I can only run the S versions of the RemoveGrain().

So I decided to up the strength but then I saw jaggies and tried 1.5 supersampling. It brought the P4 down to it's knees. Forget about playing DVDs, it was having a hard time with an AVI file.

So I wondered what improvement was there between the original LimitedSharpen and LimitedSharpenFaster. It seems to me LimitedSharpenFaster lost it's edge, or is the edge only found in SSE2/SSE3 P4's with dualcore?

Seems like you need a pretty hefty machine to do 1.5 or 2.0 SS, Lancos4Resize, etc with the MT version of masktools running on a 3.4GHz dual core system with a high end video card like a 6600GT+...sheesh.

I was playing with Lancos4Resize and read the thread on it here on AVSforum linked from doom9. I was surprised to find a cleaner video by itself compared to LimitedSharpenFaster by itself.

I cannot run both as my system bombs. I know that would get the best output.

Mr.Bitey

02-08-06, 10:01 PM

SpeedyHTPC,

as fas as I know....

You'd need supersampling to remove/reduce jaggies - I cant see how sharpening alone would help - it'd only make it worse... (on a side note, I find mergeluma to highlight jaggies whereas hqdn3d does not)..

Limitedsharpenfaster just has some of the code written into a DLL file rather than within the script - DLL's run faster

You should see a speed improovement with LSF compared to straight LS - without dual-core/hyperthreading etc..

The advantage of dual-core etc comes from running LSF with MT and or the multithread version of avisynth..

You can get some small speed improovements running the SSE2 or SSE3 optimized versions of some of the functions (eg removegrain)..

Seems like you need a pretty hefty machine to do 1.5 or 2.0 SS, Lancos4Resize, etc with the MT version of masktools running on a 3.4GHz dual core system with a high end video card like a 6600GT+...sheesh.

SS yes - but resize (lanczos4) is a single threaded function - you get no benefit running dualcore...

I was playing with Lancos4Resize and read the thread on it here on AVSforum linked from doom9. I was surprised to find a cleaner video by itself compared to LimitedSharpenFaster by itself.

I used to run lan4resize (1776x1000) with luma sharpen 1.20 (and denoise3d fast) - but I find LSF, then lan4resize (1776x1000) to produce a nicer image - albeit with only a small sharpen (30) and no SS...

I cannot run both as my system bombs. I know that would get the best output.

I would imagine a LSF with SS1.7 and Sharpening around 60-80 then lan4resize to 1920x1080 would be quite nice indeed :-)

This is what I dont understand..

I would think a mere SS of 1.3, Lancoz4Resize of just 1024,576 to match my BenQ 7800 PJ and LSF would do..but no..it runs my P4 CPU at 80% already with either Lancoz4Resize or LSF alone..

I guess my P4 is too old even though its a 3.0GHz version. The only version of RemoveGrain I can use are the S versions. I cannot run SSE2 or SSE3 on this P4.

SpeedyHTPC

02-09-06, 01:30 AM

BTW I cannot Lancoz4Resize to anything like 1920,1080..it would be at 100% CPU.

AviSynth 2.56a
ffdshow latest build
dscaler 5
Zoomplayer Pro 4.51
LimitedSharpenFaster
Lanczos4Resize
mt_masktools 2.0a26

Using the S versions of RemoveGrain. This is running on my Pentium 630 3.0GHz HT.

Same thing happened on my HTPC which is an older P4 at 3.0GHz.

I believe it's the other way around - Smode 3 ought to give slightly higher quality than Smode 4; Smode 4 should be a bit faster. I can't tell the difference either way.

Hmm. Wha are your system specs and what kind of settings have you got? Lanczos4 putts some pretty heavy stress on a system - will it work with Lanczos2?

Anyway, I have had some similar problems - in fact, I couldn't get any ffdshow or avisynth resize at all. For some reason, the problem seemed to disappear after a fair amount of twiddling, but I never did find out exactly which twiddle did the job.

I finally got my problem banished by (1) tightening my RAM timings (for 3,4,4,8 to 2,3,3,7), (2) enabling dual channel, and (3) adding a modest OC (from 2.8 to 3.05). The first two improvements were actually areas where my bios wasn't taking advantage of what my system should have been doing all along; the third was an experiment that has worked out very well: temperature increase has been low enough that I can still let my system run in silent mode.

These moves have opened up enough extra power to get ovre the hump. My CPU levels still tend to go extra high for a minute or two at the beginning then drop back - by I have just enough juice to push through.

SpeedyHTPC,

Overclock it!!

All,

If you have a copy of oceans 12 (PAL R4 in my case), the openining scene is what im using to test for stutters - ive found this to be one of the most demanding.

The area where stutter occurs on my system is:
There is a single mild stutter immediatly as the camera zooms out back from that glass-bowl, then major stuttering when brad pitt walks to the right (on screen) behind a pillar then towards the camera, around the pillar and walks left (on screen) the camera pans to follow him, and its just as he walks around that pillar is where the major stutter is.. Another major stutter follows a couple of seconds later as he walks into the next part of that room (walking left on screen) there is a tall-light (with white shade) in the foreground I think as the camera pans left to follow brad, there is a stutter just prior to that light going off-screen on the right.

Ive really had to wind back my settings to get that scene smooth... I would be very interested to know if anyone else has the same issues. If i get that scene smooth then there are no more stutters in that title, or other titles I have viewed..

Cheers.

My bad - I didnt realise it was a laptop (I didnt read properly :-)

Ive had ZP complain like that (just quit) when I put ffdshow denoise3d denoising prior to avisynth - I then added levels prior to it and that worked (but was too slow).. Levels (just adjust by 1 somewhere) converts the colourspace - perhaps it was this sort of problem..

It didnt really make sense why it worked with levels and not if it wasnt there - as dscaler5007 was set to use YV12...

Doesn't using LanczosResize defeat the whole purpose of LimitedSharpen? AFAIK, Lanczos algorithm does some sharpening of its own.

Thanks Mr Bitey..

Of the HW you spec'ed I'm not too far behind. No matter what I set for LimitedSharpenFaster, SS at 1.0 or what, Zoomplayer bombs.

zambelli,

Yes thats true. Lanczos4Resize does do a bit of sharpening and Lanczos4 does it best. Check the thread on the comparisons of screenshots. I'm almost willing to do just Lanczos4 by itself to 2* the size of my PJ's native output. It is very sharp.

http://www.avsforum.com/avs-vb/showthread.php?s=&postid=4760581#post4760581

Check Charles Black's comparisons of the various modes of LanczosResize with the pics on post #64, page 3 of that thread. Best way is to load it with Firefox in tabs. Lanzcos4Resize with LimitedSharpenFaster would give you a nice 3D look.

using MT5.0, masktools a26 (and the limitedsharpenfaster.avsi included with a18 I think it was).. SSE2 version of removegrain

With those settings im ok.. If I up strength to 40 - I get stutters on the oceans12 opening, or if I up hqdn3d(2) I get the same.. Ive tried adding a touch of luma sharpening in ffdshow but at 0.40 it introduced stuttering...

CPU usage hovers in the high 50's low 60's (Hyperthreading).. FPS in ffdshow is too erratic - goes from low 30's to low 20's but playback is smooth..

Ive tried mergeluma or using denoise in ffdshow - but it just doesnt quite look as good as hqdn3d even at 1...

Lan4 by itself (no limited sharpen) is pretty good - nice and smooth and reasonable sharpening (i used to use it with luma 1.20 sharpen)...

I'll turn Lan4 back on (in the LSF combo) and see if its stutter - free... ive gotta warm up the kit anyway for some viewing a little later..

Now this is odd... Ive just changed the settings to Lan4 resize (from lan2) (1776x1000) and im now able to up the strength to 50 and not get any stuttering on my test scene - i got some the first run, but subsequent runs have been smooth - it could have been a 'bug' some people (inc me) get when pausing/starting/ff/rr a movie.. No other changes...i'll go run some more tests and see how high I can push strength.. It must be close as I can see it hesitating slightly - not quite stuttering... but not perfectly smooth :) I could be imagining it....

Ran some more tests... Running strength 90, and upped hqdn3d to (2) and still smooth!! - I didnt think the script was running, so I added SS 1.6 - that sure put the stoppers on it.. Put it back to SS 1.0 and smooth again.. I think its time to ghost the HTPC and never touch it again!!

It seems Lan2 was my stumbling block.. Im using andy's SSE (I think its sse2 but could be wrong) optimised version of ffdshow (20040801a).. Lan4 and im now sitting pretty.. the wierd thing is, CPU usage is in the mid-high 60's now (performance monitor) wheras it was stuttering in the low 60's previously... so all I can think is that Lan4 is more optimised than lan2 (I thaught andy optimised upto tap4...)

After more testing... I upped the strength to 200 - still smooth... I then put it back to 90 and watched the rest of a movie.. I then went back to my test clip and... stuttery again - at 90... I reduced overshoot to 1 and it was pretty smooth..

Not sure whats happening here.. might reboot and see if something has turned evil on me...

zambelli,

I didnt think LSF has destx and desty.... might be better to do it in there, BUT i dont think you can resize with MT as it splits the image.... (maybe thats why we dont do it :-)

Cheers,
Bitey

Aiieee... Ok, is there a point I should start reading this thread at? It seems like things have changed pretty significantly ince the start, and Socio's guide is gone :(.

Thanks,

There was a mirror to socio's site which was still alive - there are some links to it back some.. Looks like socio's site is back: http://free.hostdepartment.com/f/ffdshowGuides/adv.html

Has anyone been succesful in getting MT working with a dual core Pentium? I have it working fine on a single core Pentium 3.4Ghz using hyper threading but the dual core causes the image to get screwed up, it looks like the frames are being overlayed on each other. My guess is that the frames are being processed out of order.

Reclock 1.7 beta 4
Video Renderer: VMR9 Renderless
Audio Decoder: Dscaler5 (output via Spdif)
Ffdshow version: Andy's ffdshow-20040801a_preview_SSE2

Fdshow filters used (in order)
1.Denoise3d 0, 0, 4
2. Resize 1360x768(Lanczos4 L.80)
3.Avisynth
Import("C:\Program Files\AviSynth 2.5\plugins\LimitedSharpenFaster.avs")
colormatrix()
LimitedSharpenFaster(ss_x=1.0,ss_y=1.0,Smode=4,strength=80,o vershoot=7)
4.Output yv12

I tried doing the lanczos resize within avisynth but it resulted in major stuttering. Andys version of ffdshow is the only one that i can use without getting any stuttering. Also using the SSE2 version of Removegrain

Is it true that the Limitedsharpen script have is own denoise function (Remove grain ???)
So is it necessary to use denoise if the script denoise the image ?

Mr.Bitey

Beamer,

Sounds wierd - are you using a26 version of masktools?

Some of the other versions (between a18 and a26) had a problem with frame order..

Yeah, dest_x and dest_y are documented and supported. You're right about not being able to use them with MT though.

I think using BicubicResize would be better than using LaczosResize with LSF because BicubicResize won't additionally sharpen the picture.

Also, if resizing is being done via BicubicResize or LanczosResize, the resize function should always be before the LSF function, otherwise it's rather useless.

Thanks for your response.

Yes, I'm using the latest masktools.dll dated 29/1/2006 but I have not tried the limitedsharpenfaster that's included in the file. I will give that a try to see if it resolves the issue.

That would be nice, if we all had superquick CPU's :-) I certainly cant resize before LSF... well, and not have it watchable anyway!

I believe remove grain is used as part of a sharpening routine withing LSF its not used to denoise the end result so to speak.. However theres nothing stopping you using removegrain outside LSF if you prefer that denoiser..

You should run a denoiser first to avoid having LSF sharpen noise as well as detail you want to keep.. Some run medium/heavy denoising prior to LSF, then a light denoiser after resizing to reduce any noise/artifacts created by sharpening..

Bitey

metallic,

Thanks for sharing your settings.. Im pretty sure that your denoisnig with those settings is doing nothing... IIRC the time parameter (that youve set to 4) doesnt do anything unless you have values for luma and or chroma and with the preview version, if fast is selected - anything under 1 from luma/chroma is treated as 0... (i'd have to go read the ffdshow faq again to find it :-)

I'll give your settings a shot and see how they go on my kit..

Bitey

Oooop's Bitey you were right on the money. I screwed up when I copied the file to the dual processor machine. Works fine now, got a bit worried by a thin line across the centre of the screen but found removing the overshoot 7 option removed it.

Is there an advantage to using the LimitedSharpenFaster over the latest updated LimitedSharpen ?

Thanks again for your assistance,
Chris

I just tried the 02/03/2006 version of ffdshow SSE2 and it's working great. I had stuttering at anything higher than x1.15, y1.15 and this one lets me crank up to 1.3 without a hickup. Also using ZP 5 beta 3.

AMD-64 cpu.

Now heres a strange thing..from joeuser2's link I can run fddshow SSE2 on my HT but I can't run RemoveGrainSSE2???

Do I need SSE2 of fddshow?

well..tried that and zoomplayer still bombs. I can see that CPU goes way high just before it dies.

Mr.Bitey

02-12-06, 06:06 PM

Beamer,

Cool - ive found that line means your not running the right version of something (in some combination)...

Make sure youve copied the version of avisynth from MT05 into the avisynth folder and your windows/system32 folder (I think this is the culprit).. but if overshoot fixed it.... sounds a little bizzare but might indeed be the case!

Cheers
Bitey

Mr.Bitey

02-12-06, 06:08 PM

SpeedyHTPC,

Have you tried using lanczos4 inside the avisynth script ?? - might be worth checking...

So whats your the order and settings your trying?

Cheers,
Bitey

SpeedyHTPC

02-12-06, 07:51 PM

i tried to find examples of that, can you give me one?

I'm just running LSF() then Lanczos4 after on separate lines.

I've set Lanczos4Resize at 1024,576 to match my PJ and I'm running LimitedSharpenFaster with SS at 1.0, overshoot 7, strength 90. Pretty much the basics until I can run them both.

However either one is pushing the CPU at 80-95% already by itself.

I really like to do Lanczos4Resize(2048, 1152) and LimitedSharpenFaster with SS at 2.0, strength 100.

Mr.Bitey

02-12-06, 08:00 PM

SpeedyHTPC,

Thats it :) its just a single line eg:

Lanczos4Resize(1280,720)

The other way (and the way im doing it) is to do the resize in ffdshow and not in avisynth... give that a shot too and see if it works then.

Cheers,
Bitey

I see..well single lines work.. I had tried resizing with Avisynth but that didnt work before. I'll look again.

a27 of masktools is out - small bugfix (not a LSF related one).

Bitey,

When i use the denoise3d settings it make a noticiable visual difference to the image. I far as i understood it using the fast setting disabled the Luma and chroma options, which have no effect when under 0 anyway as you said, and only the time parameter was used. It is definatley working as there is a clear denoising in the image.

cheers,
metallic

Mr Bitey,

Resizing with AviSynth and NOT within the script of Lanczos4Resize will give me a weird image. So that didnt work.

Wow. That sounds like a really, really distorted image. I know quality is subjective, but I just can't believe that would look good. Please don't take it personally - I'm just skeptical.

I'm just running LSF() then Lanczos4 after on separate lines.
Like I mentioned before - I think you're completely canceling out any benefits of LSF by additionally sharpening the entire image with Lanczos4. Can you provide some screenshots?

Mr.Bitey

02-14-06, 11:36 PM

zambelli,

What resizer would you recommend using?

Cheers,

02-14-06, 11:45 PM

FYI...
I was doing some comparisons of Masktools a26 versus a18 last night and it seemed like the performance had actually gotten worse with a26. I purposely set LSF very high in order to peg the CPU and then monitored the average fps and dropped frames. I saw about 0.5-1.0 fps better performance with a18. This was on a single proc 2.93 GHz Intel, with SSE3 build of RemoveGrain.

It'd be nice if the Masktools devs ran some regular perf tests with every build so we could have these numbers before we install the builds.

zambelli

02-15-06, 12:13 AM

What resizer would you recommend using?
I'll make two points:
1. I think resizing is only useful if it's done before LSF(). Otherwise you're just wasting CPU time by blowing up sharpened pixels in software. If the CPU isn't powerful enough to resize before LSF, then you might as well let the video renderer do the final resizing.

2. LSF is designed to be better than your average sharpener. From Didee's description: "LimitedSharpen() applies one out of three different sharpeners (two domain sharpeners or a windowed range sharpener) to the source, but will limit the oversharpening (either 'hard' or 'soft') IF it exceeds a defined overshoot." AFAIK, LanczosResize just sharpens the entire image equally with no consideration for oversharpening. Someone please correct me if I'm wrong. Applying LanczosResize together with LSF is then double sharpening. If that's anyone's goal, why not just tweak LSF to produce that much sharpening in the first place?

If you're going to resize before LSF, I recommedn BicubicResize or LSF's own dest_x and dest_y parameters. It'll be faster and is less likely to produce an oversharpened image. Just my 2 cents. If anyone has screenshots that prove me wrong or wants to put it up for a vote - all the better.

new version of masktools has been released

it seems to be a speed/bug fix version

http://manao4.free.fr/masktools-v2.0a27.zip

* fixed : mt_binarize asm optimizations that borked with some thresholds

I have made another discovery

in the the masktools zip file is a newer version of limitedsharpenfaster, last updated on 21-01-2006

If i understand correctly that version uses the limitsharpen.dll that is intergrated into masktools, this version is also newer the the regular DLL

this means you do not need the limitedsharpen.dll anymore

Also i managed to find some newer builds of ffdshow

http://kurosu.free.fr/ffdshow-20060127-05H49-athlon.exe

http://kurosu.free.fr/ffdshow-20060127-05H49-P4.exe

http://kurosu.free.fr/ffdshow-20060127-05H49-P3.exe

Remeber to download the correct version for your cpu

this new version should be faster/stabler/better or none of the above ;)

and a new version of dscaler
