Who can tell me which is the best website if I want to get some information about video processing? I appreciate you.

There is no such thing called 'best site' on video processing, given that most are excellent sites and it is up to you to educate yourself on how to 'process' your video.

Of course, you should have a look around the homepage of Digital-digest and browse through its forum to 'digest' what knowledge you find useful. Doom9 is another excellent place to have a look at. It is more frequently frequented and is updated much more regularly.
