FFmpeg has "concat" file format which is a text file containing all the
concatenated files. Create a text file (e.g. "list.txt") which contains
lines like this (without indentation):

    file 'video1.mp4'
    file 'video2.mp4'

Then use a FFmpeg command line like this:

    ffmpeg -f concat -safe 0 -i list.txt [...]

In the place of "[...]" you will have all the codec, filter and output
options. Some examples:

    -c copy ready.mp4
    -c:v libx264 -crf 24 -c:a aac -q:a 2 ready.mkv
