Good! The cat command do the work! Good to know for MTS files by Panasonic. Thanks!
For the other questions about Multicam, are you in the right way?
Over time I have repeatedly tried to create a script that would take the various media + external audio collected in a folder, do audio/video synchronization, and then delete the internal audio tracks and replace them with the external one. I thought it could be done with ffmpeg and its feature. Unfortunately, I do not have the capability and have always failed. One could also introduce, in such a script, the concatenation of the files.
1- collect the files into one folder (video files+internal audio; external audio).
2- Synchronize the files with the external audio track (your choice of timecode or waveform).
3- Duplicate and break the external audio track so that there are coincidental chunks with the various files.
4- Associate the audio clips with the relevant files.
5- Delete the internal audio tracks leaving only the external one.
6- Concatenate the files for each camera/scene with which they were recorded (also leaving blanks if they are not strictly consecutive).
I guess it would be a real program rather than a simple script.
@igorbeg I didnt work on the other parts for the moment. I wil retry monday. I think i will have a more time.
Yes, i think a script is not the right term in this case.
