The VideoLAN Forums

I've got some Quicktime videos with an audio track in AAC and a video track in MPEG-4.

Is there any way to convert the file to an .mp4 file without transcoding the audio and video tracks themselves? In other words, take what's in the Quicktime container and slap it in an .mp4 container without actually recompressing it.

This is on VLC 0.8.6a, Mac OS X 10.4.8 on a Dual 2.0Ghz G5 with 3.5 gigs RAM.

I'm trying to get the video onto my iPod, hence the question!

Thanks,
Richard

If you have Quicktime Pro you just have to "Export as MPEG-4" and select "Passthrough" for both Audio and Video codec.

I think you should be able to open the file, select Stream/Save. Choose the output file and an encapsulation, which would be mp4 in this case. Leave the audio and video codec options alone.

From a command line, it should look something like this:
From some quick tests, if the encapsulation doesn't support the audio/video codecs, then the unsupported stream is not included ... but then again, theses were some quick tests and not thorough at all
