Camtasia works really nicely for doing floating head videos and it has options for dealing with green screens and video touch ups.

That also means it works fine for doing product review videos or vlogging. Basically video coming in from a single source.

It's not comparable to something like after effects but if you just wanted to record something with a video camera then Camtasia will work no problem for both the recording and the editing of that video.

All of its animations, transitions, zoom, panning and pop up tooltips can be applied to that film recording just like you could with a screencast recording.

You can even combine both that film recording with your screen recording as different tracks. It really is a versatile product for all things related to creating videos.

I'm not affiliated with Camtasia either, and I would switch to an OS solution immediately if something existed that was comparable but the only tool that I know of that is remotely close is Screenflow and it's MacOS only + paid, so it's basically just a direct competitor to Camtasia (Camtasia runs on MacOS too, and its project files are compatible with both Windows and MacOS).
