Let's get started with python and ffmpeg

Pick and download a video with a lot of edits. New coverage is good.
use the PySceneDetect tool (link on main page) to detect the scenes and extract them. (You need to install Python and ffmpeg) scenedetect -i goldeneye.mp4 -o output_dir detect-content -t 27 list-scenes split-video
reattach the clips in a different order with ffmpeg:
make a playlist file with the content:

   # concatenate the following clips together
   file 'goldeneye-Scene-008.mp4'
   file 'goldeneye-Scene-005.mp4'
   file 'goldeneye-Scene-018.mp4'

5. run ffmpeg ffmpeg -f concat -safe 0 -i playlist.txt -c copy output.mp4

Bonus learn some python to further automate the process
