I have planned a Four Camera Chroma with ATEM Extreme. but this has only two media players working two chroma but the background is not switching. I have tried my best and have more than 50 videos on YOUTUBE "How to do FOUR camera chrome keying" but no one is teaching.

I have almost all my shooting gear from Blackmagic. Can you please help me with this?

I am still waiting for a reply. How to do 4 camera chroma keys?

Hello Visionaryradio!

Are you working with macros? Using a macro, you can, with a single button, change the camera input, and the chroma key settings for that camera, place the background you want to use from the pool into one of the four slots (or two if that is what you model supports), and then place that background behind your keyed camera.

Once you set this up, a single button press on the macros will do all of that in a single frame allowing you to cut cameras with different backgrounds in a single press.

The bonus is that you should be able to use your other media slot for something else, a lower third, corner bug, or even full-screen slate.

While I have not done multiple chromakeyed cameras, I have done similar uses of the macro button.

Give this a try and experiment!
