Show HN: Lapser Studio – Beautiful timelapse screen recordings effortlessly

This is interesting, but I've got questions.

I spend a lot of time in Screen Studio (I make videos for software companies) and this looks similar, but for time lapses specifically.

I can see the use case for digital artists. But the talking head demos are confusing because I'm assuming you can't hear what the spokesperson is saying (otherwise they'd sound like a chipmunk) - so what's the point of having them on screen during the time lapse?

I use retiming a lot to speed up screen footage but never speed up narration. Can you time lapse the screen footage while keeping the spokesperson footage 1x?
