Editing X264

Hi, what application can I use to edit a .mp4 file encoded with X264+AAC?

I want to split the video in parts.


thanks in advance

Try Avidemux if you need a GUI.

Lets you do this without the need to re-encode. MP4Box is part of the gpac package in the repository.

I just checked out gpac. Wow, there's a lot more than last time I looked at the project. The MP4Box solution would technically be much better. With Avidemux, you would be re-encoding (going down a digital generation).

No.

In smart copy mode, Avidemux will only reencode those frames which lost their reference frames (I-frames) due to a cut. If you cut at I-frame positions only, no reencoding will be done.

Thanks. That's good to know.
