Help : How to remove grains from old video clip ?

[DonSeenu]

Anybody can help me about how to remove grains from video, and make clean frames ?

With a denoiser. AviSynth, Virtual Dub, and many NLEs have them available in varying degrees of quality.

Please give me more details about 'Denoiser'.

I don't know. The word 'denoiser' is pretty self-explanatory. They remove noise, film grain, sometimes small amounts of dirt and other crud in your film. I use AviSynth and here's a page on some (only some) of the denoisers available if you use AviSynth:

Maybe if you provided a short ten-seconds from your source (DVD?) you will receive more informed advice on how to treat it.

And if you do a Google search on 'denoiser' you'll find much more information about them, for both audio and video.

manono also mentioned VirtualDub, and that might be a good place to start. A bit simpler to use, though not as efficient as AVISynth.
