#Name:Edit Video i1 v1
#Description:Using the source video recordings created the completed edited version
#Usage:Enter a directory where temporary files can be written, and the finished video can be saved. Edit the 'SOURCE' and 'TYPE' variables to have correct details. Add in commands for extracting video segments. Run the script.
#Notes:Tested on Debian 10. There is technically double conversion, but the first conversion should be visually lossless so it doesn't really matter. This script was made for my own use so it's not very user friendly, and doesn't do error checking. I'm sharing it as an example. You'll almost certainly want to edit it before using it.
