Ask HN: Screen recording software with real-time zooming?

I would use OBS with some added plugin [0] to allow zooming on your cursor with a hotkey.

What do you mean by real-time? Do you want your screen to zoom while you are recording? Or do you mean that you want the zooming to happen automatically?

I want to ideally press a hotkey and have the recording zoom into the area of the screen I'm interacting with the mouse, then hotkey to zoom back out to see the full application.

Often these tools live somewhere under Accessibility settings - at least for macOS that is.

Have you tried Windows Magnifier?

Good suggestion, unfortunately that zooms the entire screen including the recording software so it's not exactly usable for the types of recordings I want to do. Ideally I want to zoom in on just part of the active window.
