to be fair if you don't know about screen studio why are you looking at an oss alternative?

I don't know about screen studio, but if I were looking for a way to edit screen recordings I wouldn't be searching for an "open source alternative", I would be searching for "open source software"

Defining your project as an open source alternative to another program is a mistake I think

Fuck me for being interested in projects posted on HN, I guess.
