> The problem is the video. Only the first video looks perfect.
> The second visible is not visible--it became "blocky" after the concat:

>                ./ffmpeg -f concat -i files-list.txt -c copy output.mp4

(Complete, uncut console output missing.)

If the input files are incompatible, you have to reencode / use
the concat filter.

Please do not attach output files, Carl Eugen
