@e8johan ah, I didn't quite understand the script thing in Kdenlife, I thought it somehow can import some scripts, but now that you mention it yes! That's a great idea!
@e8johan thanks to your thoughts while researching I stumbled uppon https://thediveo-e.blogspot.com/2016/06/kdenlive-adding-meta-data-and-cover-art.html which mentions that when setting up notifications for rendering finished, you can make kdenlive to run a script and you can pass it the path to the rendered file!
