Hopefully posting in the right place.

I'm on Mint 19.3. Have been using Kdenlive 17, but got frustrated and went to 21.04 - soooo much better.

I'm only able to use the flatpak and appimage versions on 19.3, it seems. When I write a video to render by script, it writes the .mlt file to the videos directory, but there's no .sh file to run anywhere. Am I missing something?

Many thanks for any advice.
