I have a 4K camera as an input in vMix. Resolution is 3840x2160. In the camera input I go to Settings -> Position -> Zoom. Instead of using the zoom slider, I set the zoom to 3. What resolution do I now have? 1080? 720?

Asking for 100 friends. ;)

I did a little experiment. In Photoshop I created a 4K sample image. Then I overlaid reference 1080p and 720p images.

In vMix, with zoom = 1.0 the entire 4K image is visible full screen.

When zoom = 2.0 the 1080p size portion image is visible full screen.

When zoom = 3.0 the 720p size portion image is visible full screen.
