Extract and copy chapters from one M4V to another

[gevorg]

How can I transfer chapter marks from one M4V file to another? Both have the same time length and same codec (H264, AAC stereo).

Well, maybe this was not a "newbie" question. Here is one way I figured out how to do this (if anyone interested/stumbled upon this thread).

Download MP4Box and use the following in command prompt:

mp4box "C:\Source.mp4" -dump-chap

- This will extract chapters from Source.mp4 file to a newly created Source.chap file (you can edit this file in text editor to adjust chapters)

mp4box "C:\Destination.mp4" -chap "C:\Source.chap"

- This will place chapters into your mp4 file. Test on your desired playback software/devices to confirm compatibility.

Thanks for posting your solution. Yep. mp4box can do most stuff with mp4s.
