I would like to merge them into full.mp4

I tried to use:

Answer 1

I did that with avidemux (gtk tool). It is available as a package under most linuxes, also for Windows and Mac. I simply opened the first file. Then I added the next ones in order. Finally, I saved the concatenated video using audio and video copy and format mp4.

It worked great !
