The auto-rotoscoping feature seems very useful if it works well. Auto-rotoscoping in After Effects can be extremely finicky and usually requires frame-by-frame touch ups. This would be very useful for people without green screens.
I just tried their software and it's... uhhh, no way this is better than AE, unless (and very possible) I'm doing something wrong, this isn't baked software. I tried playing with it, it glitched out like crazy, and then eventually chrome on my M1 MBP locked up, tried again, same deal. My degree is in digital imaging technology so I was pretty curious to try it.
Edit: I just spent the last 25 minutes persisting with it, I'd say their auto tools are actually worse than AE. I guess it's a consumer product, but even then... seems like you'd be spending a lot of time for little reward, for example, it's not clear to me how I might refine this mask: https://share.getcloudapp.com/rRujBABR
Edit 2: I'm gonna be a little more generous and say I think the mask itself is pretty good, it can deal with some pretty complicated situations well, but the tooling is very remedial.
