ATEM Plus multi camera virtual set

I ve come across a software called "Atem Plus" on youtube, Anybody use this software ? I am trying to connect with ATEM 4M/E but fail to connect.
Is there any other way to produce a similar effect on a new ATEM, maybe using Macros on Atem ?

The problem will be that your ATEM 4M/E has the advanced chroma key but that software is trying to use the classic API.

I have added the advanced chroma key to my PowerShell scripting solution but have not been able to test it (no access to a TVS 4K pro or 4 M/E unit).

You can do it with macros, it will just be slow to set up. Once you set up one macro for one camera, you would be able to export it and then make copies for the other camera shots and import back into the switcher.

Thanks, lets see if i can be done
