QuickTime can record a window... low computational overhead, and built-in.

Also when you move or resize the window? Or can you just set the fixed frame for screen recording to a selected window's initial frame?

Can it? File / New screen recording just gets me the same cmd+shift+5 interface.

"capture selected window" or just press space

But that’s just a screenshot. You can’t do that with video right?

[jbverschoor]

With both.. it's the same interface

You can't record _videos_ of a specific window though. You can only record a fixed region of the screen or the whole screen. "Capture selected window" only deals with screenshots, not with video.
