If you need to create MP4 files, you can use mp4UI. If you just want to play the MP4 file, you'll need the MP4 codec from http//www.free-codecs.com/

how to make videos run on VCD from digital camera that its file extension is (avi) without problems or wrongs.
that means converting from one extension to other with keeping sound and movie as same when recorded.

Can I store two different video types in the same file? I mean like one encoded with h264 and another with h263. I want them to be stored in the same file to do some experiment.
