I use Movavi Screen Recorder (
https://www.movavi.com/screen-recorder/), which can generally be had for $25, because I like the way it can be configured to highlight mouse position, mouse clicks and function-key presses. I wish it could also add key-click sounds. If you're making tutorials those things are considerations.
A nifty side-feature is that it can sort-of shoot a panorama of any scrolling window, such as a web page, making a single large image with the entire contents. Handy if you want to scroll those things in Resolve.
Whatever software you use, set it for a constant frame rate. Resolve often has trouble with variable frame rate media, causing flicker and that sort of thing.
