View Full Version : What kinds of postprocessing video filters do you use?

I have never used such filters. (I had CRT TV, and today I'll buy a 37'' 1366*768 LCD.)
Mainly I'm interested in the upscaling filters, because I playback xvid, divx files (which are relatively low resolution), and 480p and 720p content.
Of course any other filters which can improve quality are appreciated.
Thanks

The setups here are good...

I use the SeeSaw configuration (sharpen + denoise) and sometimes just SeeSaw alone if the source is clean.
You can always setup ffdshow to resize as
Resize & aspect:
Multiply by 2.000
No aspect ratio correction checked
Lanczos
Taps: 2
It will double the res and make the picture sharper

Indeed. ffdshow is excellent for these setups. Make sure high quality RGB conversion is enabled.

Thanks, I have tried it (Athlon64 3 GHz, 1GB RAM):
1. resize: it's working, and it looks good
2. seesaw: when I turn on, my PC is almost smoking ... :) So I must turn off ... :(
What kind of CPU do you have ?
I have modified the seesaw config (which is on the above link), I don't apply any denioser:
a = last
b=a
SeeSaw(a, b, NRlimit=2, NRlimit2=1, Sstr=1.4, Slimit=7, Spower=2, Sdamplo=8, SdampHi=10, Szp=10, bias=1, sootheT=30)
Just 2 small question:
- Multiply by 2.000 : is this smart enough to know the actual desktop resolution, and don't resize above that? (i have tried and it looks so...)
- "Make sure high quality RGB conversion is enabled": what does it do? Is it makes sense to use with LCD monitors/TVs ? (perhaps I have asked a stupid qustion now ... :) )
And thanks for the answers!

Most of the time, a dual-core is pretty much required to use software resize and better avisynth filtering on playback, at least with DVD-res video.

Indeed. My Poor 3500+ can't even do limitedsharpenfaster with a 2x lanczos resize at the same time for even 640x res.
Need dual core.

Well I don't use ffdshow on DVDs, I use PureVideo instead. PureVideo plays them back smoothly and the picture quality is great :cool: I have a P4 2.8GHz + 1GB DDR 2-2-2 + GF6600GT. If I use any ffdshow on DVDs (even resize or SeeSaw alone) it makes them jittery and uneasy to watch. SeeSaw works fine on divx/xvid for me because the video doesn't need to be deinterlaced, lower res than DVD and lower bitrate than DVD.
His SeeSaw setup:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\FluxSmooth.dll")
a = last
b = a.FluxSmoothT(11)
SeeSaw(a, b, NRlimit=2, NRlimit2=1, Sstr=1.4, Slimit=7, Spower=2, Sdamplo=8, SdampHi=10, Szp=10, bias=1, sootheT=30)
SPresso(limit=2, limitC=2, bias=76, biasC=76, RGmode=4, RGmodeC=4)
Or just SeeSaw:
SeeSaw(NRlimit=2, NRlimit2=1, Sstr=1.4, Slimit=7, Spower=2, Sdamplo=8, SdampHi=10, Szp=10, bias=1, sootheT=30)
I don't know about RGB conversion...so far I only playback stuff on my wide LCD.

Thanks for the answers.
I have bought an x2 4600, so I can try them maybe in the weekend.
In fffdshow where and how can I set a similar thing like in avisynth: levels(TV->PC) (I saw the levels group, but I don't know which settings refer to this. I know that I can put this line to the above script, but maybe ffdshow's version is faster.)
There are lot of material, where the levels are incorrect.

Well, I had time to try out these configs. So, for me, the Limitedsharpen faster config is playable with every content (640 xvid - 720p x264):
- overlay renderer
- full postprocessing in every decoder
- ffdshow:
- Raw output
- Resize and Aspect: 1360*x, resize always, Don't correct Aspect ratio, Lanczos: tap=2 (all other settings is default)
- Avisynth: YV12 checked, Add FFdshow Video source checked
MT("LimitedSharpenFaster(ss_x=1.0, ss_y=1.0, Smode=3, strength=250, overshoot=1",2))
What are the benefits of using wmr9 renderer instead of overlay?
I'll try wmr9 too ...
The seesaw config (without denoising) doesn't play well at all without resizing on the 720p x264 content (CPU X2 4600) ...
