In actual fact my video's are not MP4 (generally speaking). I have video from several different brands of 'still' cameras, which include AVI and MOV : i have not looked further into the specific codecs they use.

I started by doing a search for "rotate video lossless" on google, and apart from MJPEG, I found nothing concrete. A lot of people (forum posts here and there) claimed "no", but then quite a few claimed "yes" for MP4. Additionally I came across a single thread that talked about rotating quicktime without re-encoding, but different posters seemed to have varying success with that.

So I checked out the home pages for the tools mentioned, and the claim is made pretty clearly there as well (lossless MP4 rotation). But there was nothing on how the process is implemented, either on the home pages or in forums.
