   Concatenating video with FFMPEG, a process so complex few have ever achieved it.

     @Baa Yeah it's a little bit complicated. First you have to ensure they use the same codec and that they have the same parameters. If not, you have to reconvert them using complex filters first, and it's a bit messy. Just tested it with two video files, had to do this:
     ffmpeg -i 2.mp4 -i 3.mp4 -filter_complex \ "[0✌️0] scale=320x210,setdar=16/9 [ch1]; [1✌️0] scale=320x210,setdar=16/9 [ch2]; [ch1][0🅰0][ch2][1🅰0]concat=n=2:v=1:a=1[outv][outa]" \ -map "[outv]" -map "[outa]" -r 30 concat.mp4

     @Jain@blob.cat @Baa@mk.absturztau.be Yeah if you want to do something quick and easy, it's better to use a video editor. Something like Flowblade or Kdenlive will work just fine.
     
     But if you want to create a script to automate the process, like if you are using a live stream or something, then you have to resort to ffmpeg.
