Does anyone know of an app that will let me put chapter markers in an mp4 file. I have started to rip my DVD collection to my iMacs hard drive using Handbrake, so I can easily access them all through front row, and its all going well, except obviously the chapter markers don't stay in the mp4 markers.
This is fine for most DVDs, but I have a few music DVDs, and it would be nice to be able to easily skip from song to song.
Anyone got any knowledge on how to do this?
Cheers

I'm not sure chapters are valid in a .mp4. I've done it before accidently (using metadata hootenany) and it rendered the file unplayable, and unrepairable (and i tried _everything_).

It should have just made mov files (that were playable). Can you tell me what you tried plaease?

IIRC, the QT file format (.mov), which MP4 is supposedly based on, has always supported chapter marks. Whether or not that ability was carried over to MP4, I don't know.

Well mp4 has capacity for (effectively) unlimited metadata, and chapters could certainly be considered metadata. Certain windows apps have agreed on a make-shift chapter format between themselves, and simply add the chapter list as text metadata. The real issue is that there is no "official" agreement on what metadata in a file is "chapters" vs simply a privately concocted list of arbitrary text, and so it's very unlikely that QT will treat it as chapters. I don't think this practice is even common enough yet (if ever) for the open source projects to care about it. I've certainly never seen an mp4 file with these chapters in them.
But the mov version of chapters (a text track with another track as "owner") was not transferred to mp4, that I know of.
