Yes, OBSdoes have chroma key filter effects that allow you to use green screens to either remove or replace your background. I do quite a few animations using HTML/CSS/Javascript and up until now I have either used an old version of Shotcut (20.07.11) to record them, or OBS. I have been using OBS for some time now to complement Shotcut.
