Remove part of video only using command line (probably FFMPEG)
I have a 4 hour long .mp4 file and when I upload it to Youtube the entire audio track gets muted because of 30 seconds of some song between 01:21:47 and 01:22:24, how can I remove JUST this part of the video, or even better - just THIS part of the audio from the video?

If you are sure it's just that portion of the audio, then you can just mute it:
ffmpeg -i input.mp4 -af volume=0:enable='between(t,01:21:47,01:22:24)' -c:v copy output.mp4
Depending on your shell, you may have to escape the colons in the timecodes, or maybe switch to seconds representation (01:21:47 = 4907, 01:22:24 = 4944).

Hey thanks but here's what I came up with ffmpeg -i 88595331.mp4 -af volume=0:enable='between(t,4907,4944)' -c:v copy 88595331_v2.mp4 and the error i.imgur.com/aUogYcQ.png

Instead of doing this right now, first I suggest uploading just a trimmed portion and testing:ffmpeg -ss 01:21:47 -t 38 input.mp4 test.mp4

You can do this with an FFmpeg filtergraph.
Try something along these lines:
ffmpeg -i input.mp4 -filter_complex '[0:v] trim=end=01:21:47 [v1], [0:a] atrim=end=01:21:47 [a1], [0:v] trim=start=01:22:24 [v2], [0:a] atrim=start=01:22:24 [a2], [v1][a1][v2][a2] concat=n=2:v=1:a=1 [v][a]' -map '[v]' -map '[a]' output.mp4
This particular filtergraph slices the input into four pieces: the initial video segment, the initial audio segment, the final video segment, and the final audio segment. Then it concatenates the video and audio segments together.
See https://ffmpeg.org/ffmpeg-filters.html for more details on filtering.

Try something along these lines:
ffmpeg -i input.mp4 -filter_complex '[0:v] trim=end=01:21:47 [v1], [0:a] atrim=end=01:21:47 [a1], [0:v] trim=start=01:22:24 [v2], [0:a] atrim=start=01:22:24 [a2], [v1][a1][v2][a2] concat=n=2:v=1:a=1 [v][a]' -map '[v]' -map '[a]' output.mp4
This particular filtergraph slices the input into four pieces: the initial video segment, the initial audio segment, the final video segment, and the final audio segment. Then it concatenates the video and audio segments together.

Apart from the merits of re-encoding 4 hours of video just to mute a 30 second audio segment, this won't give the desired result because the concat filter requires all segments to have starting timestamps be0. But the trim filters don't reset timestamps, sov2anda2will have non-zero timestamps and the concat filter won't behave predictably.
