ChatGPT makes a wonderful natural language interface for ffmpeg. I like to ask for a bash script that uses ffmpeg to achieve my goal. Recent example output:

  #!/bin/bash

  # Set the input file name
  input_file="input.mp4"

  # Trim the videos
  ffmpeg -i $input_file -ss 00:01:08.5 -to 00:01:11.05 -c copy shot1.mp4
  ffmpeg -i $input_file -ss 00:01:13.3 -to 00:01:22 -c copy shot2.mp4
  ffmpeg -i $input_file -ss 00:01:24 -c copy shot3.mp4

  # Prepare the list of files to concatenate
  echo "file 'shot1.mp4'" > files.txt
  echo "file 'shot2.mp4'" >> files.txt
  echo "file 'shot3.mp4'" >> files.txt

  # Concatenate the video segments
  ffmpeg -f concat -safe 0 -i files.txt -c copy output.mp4
