Looking for a handy screen recording software for presenting a website

Hi, I'm trying to create various small clips of a website through screen capture. The question is if there's any recommended software, and maybe a feature that automatically slow scrolls instead of doing it myself? I don't have a steady hand, so it wouldn't look great when I drag it down the page myself. There's a few extensions that take full page screenshots which I usually use, and video screen recording extensions but the don't work well. ( Or atleast for my intended purpose ) I wanna be as prepared as possible, as it will be presented on an expo
