my purpose is very simple in theory but I can't find any soft to do it properly.
I have two video files of the same movie. Both are incorrect at different places.
For the sake of simplicity suppose that the first file as a bug at the end and that the second file has a bug at the beginning; so to have a complete fixed movie, I just have to merge the beginning of the first file with the end of the second file.
Both files are mp4 files with a very good quality H264 encoding, so I don't want to reencode them.
The problem is that it seems that H264 encoding induces I, P, B frames in a more complicated way than H263. Thus to cut and join on a specific frame in rather hard and when I try with AviCut it doesn't work.
Bandicut claims to do it, but I was not able to check this with the evaluation version, as with this version it is not possible to cut and join without reencoding....
I would be happy to purchase BandiCut but only if it works.
Does anybody knows if it really works ?
Thanks for any answer
