I love this idea. I stumbled upon a Gist[0] from vivekhaldar[1] some time ago and it really helped out when I had to create a screen recording for a colleague. Definitely not as polished as Recut, though.
I'd like to be able to use komposition, which offered a bunch more nice features for screencast editing... https://github.com/owickstrom/komposition ...but it's bitrotted and isn't maintained any more.
My first stab at something before Recut was a Node script that did a similar sort of thing, just based on silence though, using ffmpeg's silencedetect to find silent parts and generating a cut list. And then as soon as it worked, I was like "well that's cool but I really want it to be interactive" and then... well it turned out that making a UI video editor was way harder than that script haha, but eventually Recut came to exist.
