Hi everyone,

I'm trying to set up a layered input with 5 video channels (vmix call/NDI sources). My goal is to have 4 videos in an equal "Brady Bunch" 4up, with the 5th video on top of the 4up in the center as a circle, like so:

230525 OL circle layout chroma.png (55kb) downloaded 3 time(s).

The main layer of the input is a transparent color. Layer 10 (top layer) is the above PNG with black bar borders, and a green circle in the middle that I'm hoping to fill with another video source via chroma.

Outside of VMIX, I achieved this with an upstream key on an ATEM, choosing the green color as the chroma color, and the fill as a video input (sort of a "reverse green screen").

Is there a way to achieve this in VMIX? I have tried playing with the chroma setting on the PNG border linked above, and I can remove the green, but can't fill the green area with another source.

Thanks in advanced for any ideas!

Thank you so much Paco! This is working successfully, however I need to zoom the video input out in order to frame it properly within the circle. When I change the zoom level of the video (virtual input), it also changes the size of the PNG circle. Any ideas on how I could implement this with a cropped/zoomed video, and not alter the size of the white circle?

Again, thanks so much for your helpful insight!

to have the ability to move, resize the video independatly within the green circle use a basic virtual set with the circle being a UVmap
