Thanks, this is what I was able to do, thanks to SO: https://askubuntu.com/questions/977162/how-to-remove-a-few-seconds-from-mp4-file-using-ffmpeg ffmpeg -i ch3-2.mp4 -ss 00:00:00 -t 00:14:30 -acodec copy -vcodec copy test1.mp4 ffmpeg -i ch3-2.mp4 -ss 00:15:50 -t 00:17:50 -acodec copy -vcodec copy test2.mp4 then created a file: input.txt with the two lines: file 'test1.mp4' file 'test2.mp4' ffmpeg -f concat -i input.txt -map 0 -c copy output.mp4 Seems to work locally. I have submitted it to Canvas (our LMS) who will now convert and release the video (or garbled rubbish if not).
