We use ffmpeg to concat a slate (mp4) to the end of a video file (mp4) and most of the time it works great but occasionally, like 20% of the time, the slate will have a video glitch 1 to 2 seconds into it. It appears to go black for one frame, though the source slate does not have this issue. Often if we add a frame to the precompressed file (first file) before compressing and concatenating then it resolves the issue.
Here us ab example command: ffmpeg -f concat -safe 0 -i <(printf "file $PWD/video.mp4\nfile $PWD/slate.mp4") -an -codec copy -y ./output.mp4 Most of the time it works.
