I concat media files using -f concat command but there are always problem
during the switch between stream 1 and 2.

There are artifact, it is very strange, if some part do not move in the new
video it keep the old last image and blend it with the new one.


The command i use :

ffmpeg.exe -f concat -i clips.list -codec:v copy -acodec none -movflags
faststart -y out.mp4


I use 2.8.2, but i try with different version down to 2.5.2 and artifact are
still here.


-          Every media are from the same codec h264.

-          Stream are short, between 10 and 30 seconds.
