I personally find it at least daunting, for not using strong language here. But I know at least two totally blind people and one nearly blind person that use it with success.

@menelion Not very accessible. You can navigate the UI, but it's a bit hard to set it up and rely on that setup going forward. I know that some folks managed to make it work though! It's definitely worth a try, but be prepared to explore and hack!

For basic screen recording it took me under 10 minutes to figure out how to set it up and assign a hotkey to toggle screen recording. There's some object nav required in the hotkey assignments page, but I guess I'm just used to it. You only need to add your PC screen as a source and then start recording. System audio and microphone audio are handled automatically and there are checkboxes and hotkeys to toggle them. I'm going to use it for work going forward, so let me know if you run into problems and I might be able to help. I haven't done much with it, but I learned a lot just by looking through the UI.

on Windows it's pretty usable. Sorta depends on what you want to do but I've been using it for years to stream and record screencasts. Not sure about mac/linux

I find it to be very accessible on Windows, obviously things like aligning visual sources on screen is a thing that is most likely not going to work reliable any time soon except with AI help anyway, you'd need sighted help for that, but everything else works just fine. Mac is a totally different story though, I just know one person who's happy with it on Mac with VoiceOver, everyone else who I know didn't manage to get it going reliably.

@ToniBarth It's getting better on Mac, but there are still some things that are kind of annoying to do which can be attributed to QT Accessibility being sub par compared to Windows or Linux even though it's improved somewhat. The biggest issue with it on Mac is pop up menus, like the one you get when you go to add a source or opening the context menu for one can only be navigated with the VO trackpad commander. If you try to arrow through it or use the VO keys it kicks you out, so unless you have a macbook or an external trackpad it's nearly impossible to set up. Also, the record button has to be pressed with space or enter, because doing a vo-space will mark it as checked but not actually start recording which I guess is some accessibility press not being interpreted properly by the app. If you keep that in mind it's pretty comparable to the Windows version and I successfully used it to make screen recordings.
