Well Done :)

Very well done with your project @WyattBlue :) A simple addition for your users not familiar with ffmpeg would be to add a 'volume booster' / 'volume reducer' in more user friendly verbage. Native ffmpeg works as follows with your code:
auto-editor file.mp4 --extras "-af volume=3"
Where a numeric value of less than '1' (ergo -0.5) would reduce the volume by 1/2, and a value of greater than 1 increases the volume. I often use '3' or '4' to raise the volume of recorded guests in audio / video. Most users would likely be unfamiliar with -dB usage. Either way, your script is quite fantastic and I applaud your efforts! :)
