here is the sample avi that i have been working to fix the artifacts
its PAL 720:576

i have used many filters in vdub and no luck; could be fixed with avisynth?

thanks

That is more like an impressionist painting than a video clip. Very blocky.

Full PAL frame size of 720x576 and very low bitrate @ ~484 kbps. But even then this has more artifacts than can be expected of a clip with such specs. Lot of movement, so the artifacts are really prominent. Also little or no color. Not good.

I wouldn't try and reencode this one and make a bad thing worse. If the purpose is only for playback, I would play around with the 'Postprocessing' settings in ffdshow.

This is what I got with SPP Deblocking, Processing strength=256:

Left side unprocessed: Right side processed

You may further play around with the settings and settle upon what your eyes deem fit. Hope its just this clip which you need to fix and not a full length video.

thanks for the help; unfortinatelly the video is like 4 min long

i tried a 2d cleaner filter in vdub, that helped but not alot; still the image is blocky

You think if i lower a resolution it might help?

can i use vdub instead of ffdshow or ffdshow is the best solution?

i'll play with it more

thanks

What exactly is your intention? Do you want to fix this video and archive it? Or do you simply want to watch it without getting a migraine headache with the blockiness?

If the former, understand that you have to re-encode the video and that will make it lose quality even more. Not recommended.

If the latter, do what I said with ffdshow. Make sure you set ffdshow to decode your video.

And why are you comparing ffdshow to VirtualDub? I hope you know that they are different animals altogether! :eek: If not, then please do some reading up.

VirtualDub - http://en.wikipedia.org/wiki/Virtualdub
ffdshow - http://en.wikipedia.org/wiki/Ffdshow

And if you are going to *recreate* the AVI again, then yes, a lower resolution, better cropping, higher bitrate - everything will help. If you are talking about re-encoding, then forget it.

unskinnyboy; thanks for your help

i just want to fix the video little bit better for viewing; but i dont intend to re-encode it, as you said it would be hell to do it

thanks
