DaVinci Resolve has pretty unfortunate restrictions on what graphics card drivers you can use on Linux

Does anyone know of some modern blender tutorials aimed specifically at video editing?

if possible, including capturing footage form the screen (screen casts).

This us a great addon I discovered recently, but nevertheless they have an introductory video about the Blender editor: https://github.com/GDQuest/blender-power-sequencer/blob/1.5....

I'm showing my bias but my good friend Andrew runs Blender Guru on YouTube. Admittedly he covers everything from beginner to advanced so I don't know where your skill level sits, but Andrew has a lot of content.

I had totally forgotten about Blender since I never really understood 3D animation. But great idea. Thanks for both suggestions.
