Target is to add noize to every frame of mpeg4 video. Algo is a simply color modification for every pixel in frame for example. So the question is how to solve it using .net (C#)? The program needed to read frame frame from input file, modify it and save to output file (for every frame of videofile). Possible exists some free libraries for mpeg-4 modification?

Regards!

Unless you know how to re-compress the file your file size is going to explode - just one of many facets to your problem. – D Stanley Oct 31 '13 at 13:14

Check out [DirectShow.NET](http://directshownet.sourceforge.net/) – D Stanley Oct 31 '13 at 13:16
Yes, I need to: decompress->modify->compress. File is MPG4 encoded by ffmpeg or xvid. I think MPG4 is standard format for any codec? or not? – Alexey Kulikov Oct 31 '13 at 13:50
