MPEG-4 editor ?

[MaeWanto]

Does anybody know available tools to edit MP4 files ?
Thanx.

what do you mean with "edit"?

I presume the things everybody wants and nobody delivers: split & join.

Grab the latest MP4Box (http://www.aziendeassociate.it/cd/gpac/dev/MP4Box.7z) devbuild by Celtic Druid, released a few hours ago. It should include new (experimental, and thus maybe a bit buggy) functionalities for joining and splitting MP4 files.
Further details on how they work here (https://sourceforge.net/tracker/index.php?func=detail&aid=1172028&group_id=84101&atid=571741).

Thanks a lot Virus !

split and join should also work with quicktimepro and uleads videostudio8 with the mpeg-4 plugin (i never tested the later one)

also beaware that mp4box split and join option hasnt been tested at all, so it might be very buggy

[Doom9]

can quicktime even handle AVC in MP4? After all, the AVC supporting QuickTime 7 is not finished yet.

[bond]

no qt6 doesnt support avc (also not avc in mov as created by qt7) at all of course

i now tested mp4box' splitting/concatenating option and there seem to be indeed a bunch of issues

splitting works fine on most samples but not on all, concatenating(appending) leads to a wrong framerate to be used on all samples i tried so its not useable till now

edit: typos (thx algern0n ;P )
