I've been making YT videos about the Raspberry Pi but have had no way to edit them on the pi. Are there any nice Raspberry Pi-compatible video editing apps?
apt search video editor and then
apt install <PackageName> for a package you like. However all of those weren't built for raspberrypi, so they'll lag and not fully functional. I've actually written a simple one that doesn't lag as much, but it isn't descent as well... RPI is just too weak to handle a good one.
Open shot video editor
It is a very good video editor, but I recommend editing 480p videos.
You might want to try Kdenlive, but running on anything worse than a Pi4 with 4gb of RAM will be incredibly slow. If your looking to do more complicated video editing you need to use a different, more powerful computer as the Raspberry Pi just doesn't have the capability for that sort of thing.
