When used together with auto-editor will make something like https://youtu.be/ouUkyeA0Ls8?si=ddCcf7M5BU6nP77C

auto-editor command: auto-editor file.mp4 --video-codec h264 --margin 0.05s,0.05s

My understanding is auto-editor doesn't add key frames, so the output is un-seekable, so run it through ffmpeg...

ffmpeg -i file.mp4 -c:v libx264 -c:a aac file.mp4_reencoded.mp4
