[SOLVED] VirtualDub - saving .mp4 ?

[Mr. Burns]

Hello. Is there actual some way to save edited .mp4 in VirtualDub without Full Processing mode? I tried some tips, but maybe they were too hard.

You can only save mp4 without re encoding it if you cut on special frames, the i-frames that have complete info on that chunk of video.
If you cut on anything else or add filters or do anything else you will have to re encode at least that part of the video.
So if you cut between i-frames and do your work only on that piece of the video you will only have to re encode that and can add it to the rest afterwards, as long as you don't change dimensions or quality or something.
