Basically use one 4k camera to behave like it was 4 cameras inside Vmix? I know livestream has this function and I´m choosing between these two systems. They also use this function on the Mevo system

Add camera as input and create 4 virtual inputs and crop and zoom accordingly.. Only thing, there is no automatic way of doing this at the moment..

Think this actually should be promoted and focused on. Nice feature would be to have smooth-panning between different areas of the 4k video also and it would be a killer function. Suddenly 4k cameras is da shit in streaming ;)

If you select your camera Input as your background, you can pan/zoom or cut to a preset area of the screen. A recent "Showcase" thread has some video links that illustrates this fairly well: http://forums.vmix.com/d....aspx?g=posts&t=6773 The same functionality should engage if you make several "Virtual" copies of your original Input (which you can zoom/crop as desired) and "Merge" between them.

Insert a Blank Virtual Set, click on Setup and use your 4K input as a background. Click on Camera then right click on each of the 4 windows to set your zooming and panning. Also you could insert another Virtual Set with the same 4K input as a background and set another zooming and panning area. Also, try Merge transition with it.

If i choose 1080i as working default resolution what happens to the 4k input? It will be downscaled before or after the virtual croping?

Please, is this what you guys say is possible to do with vMix? I think so. Just watch the first three minutes. https://vimeopro.com/new...g-series/video/194050584 Thank you all very much. Rob

Seems like a core function when you see the possibilities. Check this out... Done in vmix with a static image, but I do this all the time with USB cameras. Including my Logitech Brio 4k running as 2k camera.
