How do you get smooth Dscaler playback?

641 Views 11 Replies 8 Participants Last post by  PanamaMike
My current setup a PIII 1 GHZ

256 MB of ram

Cybermedia catpure card.

80gb hd + second 60gb hd.


It seems the picture is jumps when there is a fair amount of movement or panning of the camera. I used to run with 512 MB of ram and it seemed

to perform better. However, I've also upgraded the version of Dscaler and went to XP.


Is Dscaler a memory hog? If so, will the 512MB make a difference?


From my past experience even with 512 it wasn't perfectly smooth. Would moving to the XCapture card mentioned on the board improve performance? Speed wise?

You propably need more powerful CPU or try different deinterlacing mode. If you want to use TomsMoComp + filters even 2GHz P4 seems too slow sometimes. I think that memory is not your problem if you are not running any background programs.
The most I could get out of a Duron 1 GHz without dropping frames was GreedyHM with temporal noise filter at 720 pixel width.


Now with an XP2400+ I can use TomsMoComp, adaptive noise, and 754 pixel width. Only 256 megs of (slow PC133) RAM.
I found out recently that all DScaler binaries since December sometime have been shipped with SSE and 3DNOW support turned off for TomsMoComp, which probably has hurt performance quite a bit. I don't know if there is a new version correcting that yet or not. I'm not currently set up to be able to easily make one myself.

I use a 1.2ghz Duron and toms+gradual denoise and get no dropped frames ever. You may need to set sleepinterval=0 so that dscaler uses 100% cpu. Unfortunately this setting makes it use 100% regardless of what it needs, i.e you can use simple bob alone and it still uses 100%.
I've had good luck with tomsmocomp2 and the adaptive noise filter at 720 pixel width.I can also enable the sharpness filter but with this setup I'm not seeing it as worthwhile. 0 dfs with both filters enabled on my old Athlon Thunderbird 1ghz with 256mb at only SDR PC133 on a KT133 mb. Tomsmocomp(the original) with just 1 filter enabled drops frames on me.

Where does one get tomsmocomp2?


Thanks.
I don't have a copy of TomsMoComp2 but that one I think already has SSE support turned on if you can find it.


But for a faster version of TomsMoComp ("Classic") I posted a copy of the one that I use that was compiled with full support last fall. It should hopefully still be compatible with any DScaler 4.x release, and speed things up for the moment until another DScaler official release is posted.


Just unzip the dll into your DScaler plugins folder. Get it at:

I'm actually running at 800x600 for 4:3 TV sources. I'm primarily using

dscaler for my TIVO output.


I'm just using Greedy High Motion and the judder reduction feature. I'm

not running any background processes.


I'll try that plugin and see if that help.

I'm running a TBird 1.4gig with 256mb PC2100. I used to get 0 DFPS using either TomsMoComp at search level 11 or using a combination of Automatic Pulldown, Fallback to Video (TomsMoComp) on Bad Pulldown and JudderTerminator. I had Adaptive Noise filter set to 40 and Sharpness set to 255 for both setups.


That was with my old IOMagic PC PVR card. Now, using a FlyVideo 2000 card, I have no use for the Adaptive Noise or Sharpness filters, so I'm getting even less load (not to mention that I've recently upgraded to 512mb PC2700). I've noticed a slight difference under extra load conditions (web browsing, word processing or IMing while watching) between 256mb and 512mb ram, but I would have to recommend spending your $$ first on a FlyVideo 2000 card so as to reduce/eliminate your filter needs which will free up alot of processor power (side note: I've got both a FlyVideo and an Xcapture, and in my system, the Xcapture simply cannot compare; it picks up way too much noise, whereas the FlyVideo which uses the new Philips chip seems to reject all noise).


Good luck.

Kensai,


Does this card support Dscaler?


Does it support the 10bit video capture?


Thanks.
