Honestly haven't found a nice video recording UI for wayland. Been using a bash alias with `wf-recorder`. This one doesn't seem to work with Hyprland (wayland) either.
obs studio is kind of overkill but works well. You can even record several windows individually and have a different layout than what you actually have on screen.
OBS is really pretty straightforward once you get your head around, and it's super flexible. I'd hesitate to even call it overkill, as for simple screen recording you only need to touch a few settings one time. and then it's two clicks for the rest of all time. (One to start recording, one to stop, I even have them keybound).
OBS is intimidating. I found it to be daunting compared to Windows gamebar (Win+G) and MacOS (CMD+Shift+5, pick a mic). The power is worth the pain if you need it. Yet I don't recommend it to normies.
Of course Wayland is usually Linux so users are often more technical anyway.
Anyone have any other recommendations?
