Just as an adjunct ..I have seen talk of a GT540(as aginst GT440) coming
is that likely to bring anything new to this issue??
ie more grunt or cooler or less power usage??
post #32 of 161
I haven't ever heard of GT 540. GT 545 (retail) was just released.

Damn...more money! haha
Well thanks Renethx...for that thread(I occasionally look at it)
and in there the Gigabyte GTS 450 gets the nod for quietness with
this Windforce twin fan setup..so that maybe safer bet
to do the Lav CUVID and full MadVR...

Sorry on the GT540 bit ...I get so confused with these
Nvidia model numbers...after a while its hard to tell
which is newer and has better specs/GPU??

So does the the GT545 have any better points compared to the GTS 450?
post #34 of 161
If the price is $100-$120, then perhaps it is good for HTPC. GTS 450 GDDR5 consumes much more power than GT 440 GDDR5 (by 10W at idle, by 25W at video playback).

Yeah ..thanks Renethx for that info on difference in power
between GT440 and GTS 450!!

In viewing the GT545 it has less bandwith than GT 440 with DDR 5
but uses less power...and has more Cudas...144 v 96
but Gt545 has DDR3 ram.

http://www.geforce.com/#/Hardware/GP...specifications

I noticed in the thread you mentioned it seems to indicate the GT 520 has newer VP engine(maybe VP5).

http://www.avsforum.com/avs-vb/showt...7#post20542087

The GT440 with GDDR 5..is front runner for my HTPC...
but maybe I need to read that thread more and do more research
My head is starting to ache...

Yeah no GT545 out here in aussieland anyway..

They along with yourself were all involved in that other thread discussion

http://www.avsforum.com/avs-vb/showt...262246&page=57

made for very interesting reading

Renethx ..your input..has already changed my original decison(ie Gt430)
your advice is very much appreciated!!!

You won't get further information in this forum because nobody here except me tried GT 440 GDDR5.

with very nice temps.

So I will get a GT 430 for this machine...based on what has been
said here.(and have a dabble with SVP as well)

When you said only half the options could be enabled
using a 9650 and Gt430...what were they?

I assume in order to achieve a stable picture with SVP.

Then later get another quadcore(ivy bridge or Bulldozer)
with bigger Nvidia card as well ...for my 2nd HTPC(at present 2.66C2Duo)

So I am only on windows 7 32bit...so no worries on the ram issue
for SVP.
WoW...sorry what is this WoW..short for??

Finally I noticed you mentioned Splash Pro in another answer
re frame interpolation(SVP) for a guy with a projector.
Have you tried the player?..ie any better than MPHC??
How does it differ in results to the SVP?

To turn on the other half of the SVP options such as exhaustive
motion vector search, you will need a CPU with more performance
and cores. Preferably a i7 Gulftown, Sandybridge or Sandybridge-E

WoW allows 32bit apps to run on 64bit Windows

Splash Pro is a simple player with frame interpolation capability.
SVP produces better results but you have to put in the work.

The 545 is quite new, just wait a couple of weeks to see if it shows up in
your part of the world.

If you displaying the image over dual monitors, the GT 430 won't work for you.

As for DDR3, it does the job, in renethx's example the GT430 memory
controller is 50% loaded. The DDR5 card is only loaded to 22%,
you decide if you want to pay the price premium to use DDR5.

Okay ...thanks Tong Chia
So to get full SVP I will have to upgrade to a Sandy bridge
and it would need to be a quadcore...so 2500 and above?

I am only running a 116cm screen...so no requirement for dual screen.

So if only running a single monitor...the difference between the GT 430 with 1GB DDR3 ram
and the GT 440 with 1GB GDDR 5 ram...with regards to getting
full effect of MadVR..ie faster faster ram and greater bandwidth
any thoughts?

To be able to turn on everything in SVP you will need a 8Core/16Thread
Sandybridge-E or a 6C/12T Core i7 990X or 995X.

On a more realistic note a 4C/8T processor such as the i7-2600
or an i7 950 is probably something to consider and juggle the SVP
options to see what works best.

The minimum GPU should be a GTS450 or better as SVP uses the GPU.

As regards to your question on the GT430, I believe that the higher
memory bandwidth of GDDR5 goes to waste.

If you are not planning on using SVP the GT430 does quite well.

The capture below is representative of the higher loads I am seeing
with the GT430.
The BD Disk is IL Divo in Barcelona which is AVC encoded at 1080i 60fps
http://www.blu-ray.com/movies/An-Eve...-Blu-ray/7945/

Movies at 24 fps loads the GPU less.

The GT430 runs with an i3-530@2.95Ghz 2C/4T 4Gb memory
Win7 Home Premium 32bit.

Mavdr 0.65 + LavSpiltter 0.8 + Lavcuvid 0.29
(DXVA hardware deinterlacing enabled in LAVCUVID)

The GPU runs at 40% and DDR3 memory at 24% 61 degC.
MadVR drops 7 frames over a 5 min period.
The drops were at the beginning as it is synchronizing

NOTE: GPU stats on right on GPU_Z window, MadVR stats is green on player window.





If the 50/60fps option is enabled in LAVCUVID, then it begins to look like the
example from renethx.
This is not necessary as hardware deinterlacing is enabled.

The GT430 is struggling at 77% load, memory at 43% and is
runs quite hot at 71 degC

MadVR drops 116 frames over the 5min period.





These captures were done in windowed mode. There is not
a lot of difference with fullscreen mode.

The slight blips in GPU utilization was when I entered and exited
fullscreen mode.

Very interesting.

I have already ordered my GTS 450, next week I will try to benchmark different situations as well with my i3 2100 and MPC-HC, LAV Splitter, CUVID, Audio and madVR.

I just discovered yesterday the idea of SVP, and others avysinth scripts to extend framerate. I have to say that I like a lot this idea as I always hated the sluttering effect that is very very visible when panning at 23.976 FPS.
But I guess, I won't have a chance to do much with my low-power CPU.
post #43 of 161
Thread Starter 
Wow...thanks for all these wonderful readouts from your GPU
and player...it gives us all something to compare with on our own
HTPCs...I appreciate the effort and trouble you have gone to!!

On the SVP issue ...from what you have said you almost need a
high end gaming machine to run SVP at its best!
I have no idea what results it brings to the screen in practice...
but in theory if its works well...then fast action and complex shots
should look sharper and more natural...ie like looking out your window
with more depth and realism.

I have a 2nd HTPC which I am planning on updating next year
once Intel's Ivy Bridge has appeared ...and the AMD bulldozer(and maybe trinity)
have appeared. These would obviously provide the opportunity for more cores
and smaller chipsets...and thus maybe less power requirements/less heat
and more computing power(ie 6 and 8 cores).

Of course it is one thing to have more computing power
but you then have to see the software adapted to take advantage of this
extra power.

Back on the issues at hand ..namely MadVR and high resolution de-interlacing
ie 1080i 60fps(as per your blu-ray IL DIVO example).
First the MadVR issue...it seems the GT 430 with 1GB DDR3 ram
is okay for allowing activation of using the 3Dlut table.

This from what I understand is generated by using the YCMS
part of MadVR ...and the resulting table is then loaded/selected
upon activating 3DLut(forgive me if I have this wrong)

So the GT430 mentioned above is capable of doing this...
correct?(assuming I am correct on the 3DLut issue)

2nd issue with using Lav CUVID..for de-interlacing
1080i 60fps hi def blu-ray or some transport streams(.TS)
from HDTV...this is done by the GPU(when using a Nvidia GPU).
Again this from what you have said and shown( via the Il Divo example)
is also possible using the GT430 above...correct??

Most Blu-rays are 1080p 24fps or 23.976 fps
and the 1080i 60fps ones are mainly confined to releases
such as Musical concerts(bands and groups) or Wildlife documentaries.
There is also HDTV stuff (transport streams or .ts)
That could be sport of all types ...plus Documentaries/wildlife material.
It is still nice to watch them ..so we need this...
therefore its good to have Lav CUVID..to do good job of de-interlacing!!

In the future ...
The pressure may well come from 3d material
as examples ...Peter Jackson is said to be filming The Hobbit in
1080p 48fps ....and James Cameron has said he wants to do
the next Avatar in 1080p 60fps.
So unlike the 1080i 60fps stuff mentioned above...
which are half 1080 resolution per screen if you like
ie two fields make a complete frame
...these 3D movies are full resolution 1080...each frame
and in Hobbit case at 49full 1080 frames per second
and in Avatar case ..even more taxing ...full 1080 frame
at 60fps. If these work/make money ...
then the Home Theatre area will have to change.
(ie including HTPC requirements).

Most cinemas have already embraced digital projection
...so it isnt such a big leap to show these new 3d films
..just some firmware/software upgrades ..to cope with
projecting higher frame rates(48/60 versus 24fps).

Why am I babbling on about this ...its because this is what
SVP tries to accomplish(and the Avisynth variation)
thru frame interpolation(ie adding extra frames).
Our screens mostly have a natural 60fps(unless its 50) refresh rate...
so why not have that instead of what most people
do now and watch 24fps or 23.976 fps on a 60fps screen
(this is unless you take the trouble of changing
your screen refresh rate..to 24).

As James Cameron has said it is much better watching
action/complex pictures at the higher rates...your brain/eyes like it more
it looks much more fluid and has a much better sharpness
and 3d/real quality...ie once again like looking out your window.

So until I change my 2nd HTPC for a super computer... next
year(and try full SVP!!)..it looks as if the GT430 will be okay correct??
(at least for MadVR and Lav CUVID)
post #44 of 161
Technicalities aside IMHO you should consider staying with the devil you know! I have just returned an Nvidia 440 card because I was unable to get a picture that came close to my 5670 and 4670 cards!

Don't get me wrong, technically I could not fault the Nvidia 440, it worked great with Madvr and LAVCUD. However despite spending two days trying to improve the the Nividia picture, I finally concluded that AMD does something special that gives their picture more punch. I hasten to add that the AMD Cat settings that I use were pretty much duplicated as far as possible on the 440 card. The one area that the 440 card was better than my AMD cards was the default brightness / contrast settings which is quite important if you intend to use Madvr since it turns off the driver settings.

Thread Starter 
Thanks for your thoughts Beamer!
Whilst I take your point about ..better the devil you know
I havent totally done this blind...if you noticed..my video card history
on my 2nd HTPC..I went from a 4650>>GT220
and havent done a thing to it..it just worked

having said that..my 4670 has done a good job
but now ...I have seen a part of MadVR(and Lav CUVID)
I want the whole...thus the need for new card
and likelyhood it will be GT430..

I was hoping in this thread to see if maybe I had missed
something in AMD land to give me pause before going down this track.

Also I need to update ..on another area..that is sound
both cards do Multi channel PCM(the GT 220 and AMD 4670)
Whilst moving to bitstreaming sound isnt in itself a huge leap
..when you combine change in chipset size
(therefore maybe change in powerusage/heat)
plus an ability to actually use the GPU processing power
to enhance the picture..it becomes worthwhile.

So while DXVA does use some of the GPU in the 4670..
with the power of the CPUs now..it is no longer
for me a real necessity(I am using MadVR without using x264 DXVA)

Lastly I dont ever use any of the enhancements within Catalyst
..except vector adaptive interlacing...and pull down detection
and I never adjust my contrast/brightness thru Catalyst
(or for that matter in Nvidia land in their setup area)
but thru my LCD panel itself in conjunction with various Test patterns.

I should say with latest setup with addition of MadVR(small part admittedly)
I have best picture I have ever had...and if there's more I want that too!
There is certainly a learning curve to get here..and lots of reading
especially here at AVS...and I have had set backs(mainly crook AMD drivers)
post #46 of 161

@devoz

Unfortunately you are wrong. You need to read Tong Chia's post more carefully. Let me explain more. Playing back 1080p24 contents with LAV Source Splitter + LAV CUVID Decoder + madVR is pretty easy with any decent NVIDIA GPU. So our main concern is playing back 1080i60 contents with these filters (there are lots of music concerts/documentaries interlaced BDs besides HDTV programs).

Test Configuration

- CPU: Pentium G840 (2.80GHz 2C/2T), Core i3-2100 (3.10GHz, 2C/4T)
- MB: ASRock H61M U3S3
- Memory: DDR3-1333 2 x 2GB
- GPU: GT 430 DDR3 1GB, GT 440 GDDR5 512MB, GTS 450 GDDR5 1GB
- HDD: WD20EARS
- Monitor: EIZO HD2452W 1080p@60Hz (with a secondary monitor connected to Intel HD Graphics when necessary to take a screenshot)
- Test clip: Verdi, La Traviata (AVC 1080i60, DTS-HD MA), Act 1, the first 2 minutes.
- LAV Source Splitter 0.29, LAV CUVID Decoder 0.80 (video mode), madVR 0.65 (the default settings, except for switching between full screen exclusive and windowed modes [exclusive is the default])

Film mode vs. Video mode; Film mode is not a correct mode

In Settings of LAV CUVID Decoder, you will see two modes for deinterlacing:

- 25p/30p (Film)
- 50p/60p (Video)

This specifies the output frame rate after deinterlacing is done on 60i. In Film mode, you will see a nice film-like effect (i.e. judders ). I am not sure how NVIDIA deinterlacer creates a 30p stream from a 60i stream, but this is not a correct mode for contents shot by video cameras (unless you prefer a film-like look whatever the source is). So select "50p/60p (Video)" (well, this is the default mode). You can see related posts by madshi and nevcairiel here at Doom9's forum.

 

 

Full screen windowed mode vs. exclusive mode; A big difference

You will see higher CPU usage and more dropped frames in the windowed mode. Exclusive mode is the way to go. Here are screenshots of GPU-Z and Task manager in each mode (on a secondary display). Pentium G840 and GT 440 GDDR5.

Windowed mode


 

Exclusive mode (A screenshot can't be taken with Snipping Tool.)


 

GT 430 DDR3 vs. GT 440 GDDR5 vs. GTS 450 GDDR5

The number of dropped frames is displayed in the screen with madVR (Ctrl+J). So which card gives the least dropped frames at interlaced BD playback? (No secondary monitor is connected in this test.)

The number of dropped frames


  G840 / exclusive 2100 / exclusive 2100 / windowed
GT 430 235 368 1834
GT 440 GDDR5 1 0 24
GTS 450 2 1 31

 

There are too many dropped frames with GT 430 to be watchable. GT 440 GDDR5 and GTS 450 are excellent in full screen exclusive mode. None of the cards is adequate in full screen windowed mode. Processor is mostly irrelevant here.

So the conclusion is clear. The minimum GPU for LAV CUVID Decoder + madVR is GT 440 GDDR5. As for processor, a decent dual-core is enough.

Edit

madVR v0.66 improved video playback smoothness greatly.

I can't understand why you have more dropped frames with i3 2100 over the Pentium

EDIT: with the GT 430*
post #48 of 161
Maybe the number of dropped frames is more temperamental. In another run with Pentium G840, I saw ~400 dropped frames. The point is GT 430 is underpowered for interlaced contents, irrespective of the processor.

Renethx..I respect you have the ability to do testing
with these various products..ie video cards etc
(as you said partly through donations via this forum)
I havent ruled out the GT440 with GDDR5.
I have however been interested in Tong Chia's test results
and his thoughts on the issues posed.

You are really talking about Tong Chia's previous results...shown earlier.

Very Importantly....with any forum it takes time for some to repond..ie they are in different time zones..and have committments like jobs, family.
We all know this...

You make some very interesting points..thru your tests
and I take them on board...but they were in response
to Tong Chia's results. Now it is only reasonable to see
what he might have to add to your tests, results and conclusions.

Anyone who reads this(and other threads) ..and has an interest in the various hardware and software..for use in a HTPC..will get much needed added value. You for one have done so!(ie added great value!!)

Lav CUVID ...MadVR and SVP are developments which can provide some
extra armoury in getting a better picture.

So if he wants to...Tong Chia will respond
to your Test results and conclusions.

"Playing back 1080p24 contents with LAV Source Splitter + LAV CUVID Decoder + madVR is pretty easy with any decent GPU"

That was a comment you made...

..in order to use Lav CUVID..you need to use a Nvidia or Cuda cored GPU..
in order to use to use the full MadVR you need to use a Cuda cored GPU...
...are these last two statements wrong?

at present I am using an AMD 4670.

Finally whilst you did say with respect to the Lav CUVID it was concerned
with 1080i 60fps material(obviously its interlaced)
Tong Chia seems to say its not necessary to use the 50p60p button..with Lav CUVID.
so we'll see why this is...
I cant comment as I have a 4670 at moment

by the way love the source you used(ie Verdi's opera La Traviata)
the music that is..
post #50 of 161
renethx,

Can you let me know what madVR settings you are using when reporting the dropped frames result a couple of posts above?

One thing I found in the course of benchmarking madVR is that it is very easy to make the GT 430 run out of steam for advanced scaling algorithms. I interacted with Mathias (madshi) to determine the frequently used settings. This is what I got for interlaced VC-1.



The steady state for GT 430 is around 73 fps at high quality setting. It is a bit close to the 60 fps mark, admittedly. However, in all the tests, I saw that the memory controller load never went above 75% (and even that was when decoding at ~ 200 fps on the GT 520). So, I am not sure that DDR3 vs. GDDR5 really matters for HTPC.
post #51 of 161

Jackmal...sorry need some explanation...but in your graph
I assume the following two things are correct..

the VPP referred to is to do with the hardware support the card is providing
in doing the job...ie decoding..or the Lav CUVID??

and is this a GT 520...the newer 64bit card with ...the supposed extended
'VP5' type of hardware decoding support(as opposed to VP2, 3 and 4)??
post #52 of 161
Thread Starter 
Okay ..Jackmal...I just read your review over at AnandTech
so VPP...refers to Video Post Processing...namely the settings available under
Catalyst and Nvidia Control centre.

and yes the GT520 is the new 64bit card...

Considering who you spoke with ..and the tests you did...
the GT 430 seems the best way to go
considering its video abilities(Lav CUVID, MadVR etc) ...along with power usage and cost in mind.

although you did indicate a more powerful card would help
with things like MadVR.

The GT430 would seem to fill the purpose pending any new hardware next year.

I think my data and Tong Chia's observation are enough. It's up to each person how to read it, of course.

I am not sure what he meant by "This is not necessary", however. Perhaps most people prefer the 50/60fps option, and he observed that GT 430 was underpowered in 50p/60p video mode.

BTW playing back interlaced VC-1 is relatively easy (very few dropped frames). I will add data on interlaced VC-1 later.

I added the details of the settings in the post. Tong Chia also observed lots of dropped frames with GT 430 + interlaced AVC BD as pointed above. You didn't mention what test clips you used in the review (did you?). (What's madVR benchmark? ) What's your real-world experience with interlaced BDs (music concerts etc.)? You saw zero or very few dropped frames?

BTW I read you message. Let's talk about it later.
post #55 of 161
The majority of my BD collection is movies at 24fps 1080p.

The GT430 is quite adequate for MadVR + LAVCUVID here.

Documentaries and music concerts are sometimes recorded using
interlaced video at 1080i 60fps.

In order to view this on modern displays, there is the additional step
of deinterlacing the content.

LAVCUVID offers 2 options
1)DXVA interop mode which uses the hardware deinterlacer in the video engine (Select 25p/30p and check the DXVA processing box)
2)Software frame doubler (if the 50p/60p option is selected) which runs the deinterlacing software on the shaders.

The 2 captures I posted are these 2 deinterlacing modes. It is
quite clear from this data and renethx's postings the GT430 struggles
with the software frame doubler.

The GT430 in DXVA Interop mode on LAVCUVID is the basic option.

If you want to experiment with the shader based deinterlacer, get something faster.

Just to clarify these options further.

These strange terms "DXVA interop mode" and "Double Framerate" were replaced by more reasonable terms "film mode" and "video mode" some time ago by madshi's suggestion.

1) 25p/30p DXVA interop mode -> 25p/30p (Film)
2) 50p/60p Software frame doubler -> 50p/60p (Video)

Quote:
I don't think so. I've never heard of "double frame rate" outside of the HTPC world. IMHO the proper solution would be to offer a switch for "video mode" vs "film mode" deinterlacing. That's how it's usually called in the CE world, IIRC. Years ago some hardware deinterlacers advertized the ability to have a "film mode" for deinterlacing, while "video mode" deinterlacing was the default. Ideally deinterlacing should always produce either 60p or 24p. From a theoretical point of view I don't really see any sense in 30p deinterlacing output. However, for movies 30p is good enough and it saves rendering performance, so in contrast to what I just said, in practical life 30p deinterlacing output does make sense in the HTPC world to save rendering power (only for movies, of course).

So again in short: I'd suggest an option named "deinterlacing mode" with the values: "film mode" and "video mode". You could also add the frame rates to the option names, to make things clearer, e.g. "film mode (25p/30p)" and "video mode (50p/60p)". Default should be "video mode", I guess, because it also works acceptably for film sources, while the film mode does not work well for true video sources.

Alternatively it might make sense to not talk about film vs video because the option will not turn on/off IVTC, anyway, nor will it in any way influence what the NVidia hardware deinterlacer does. Practically it just changes the output framerate. So you could name the option "output frame rate" and offer the options "25p/30p" vs "50p/60p". Maybe you could add the content type, like "25p/30p (film)" vs "50p/60p (video)".

Not sure what's better...

60i -> 60p is the only true deinteralcing and 60i -> 30p shouldn't be used (that's a very bad compromise and looks horrendous to me ) for *video* contents, and GT 430 is simply incapable of 60i -> 60p.

then I want the goods...
so with that in mind...instead of the GTS 450

how about the GTX550..which is newer version of 450?

Three options in this GPU ...any thoughts??

2) Software frame doubler -> 50p/60p (Video)

The terms were used to preserve context as the discussion about the right semantics only happened much later a couple of pages away

In summary 60i -> 60p is the only true deinteralcing and 60i -> 30p shouldn't be used (that's a very bad compromise and looks horrendous to me ) for *video* contents, and GT 430 is simply incapable of 60i -> 60p.

60i->30p is definitely not happening for 2 reasons
1)The image will break up into comb like pattern. (Do you see any combing on the capture I posted?)
2)MadVR is outputting at 60fps and not dropping a significant number of frames and it does not do frame interpolation.

The setting in advisory as the actual work is done by Nvidia's deinterlacer
and not LAVCUVID or MadVR.

I can understand that you have doubts the GT430 doing 60i->60p
within the context of MadVR + LAV, but I checked on TMT3 and did
not see the 77% GPU utilization, it was around 50% at the 5:54 time
index of the captures I posted.

I also see a similar 45% GPU load running MPC-HC using EVR

Tong Chia...so your saying the GT430 can do 60i > 60p
via TMT3...and MPHC using EVR as renderer
but there are doubts for MadVR + LAV CUVID???
