Hi All
I have a 4K camera input and I'm outputting at 720.
I want to create several virtual inputs and zoom into these inputs creating a vitual input which is 720 pixels high.
How does the 0-5 zoom levels in the position panel represent a percentage of zoom in? Are there any figures to zoom at 1080 and 720?
Any help appreciated.

Your best option is to create a 4K image that has a number of 720 & 1080 sized targets and experiment with zoom/crop/placement to work out the numbers. That way there's no guessing.

With a UHD source and a 1920 project, max zoom is 2.
A UHD source and 1280, zoom is 3.
3840 / 1920 = 2
3840 / 1280 = 3
A very useful feature of vMix.
