I was trying to do three Chroma Key effects spread across one MLE, and 2 other MiniMEs.

MLE 1 - Standard 2-Box with the graphic used for the box pulled from MS2, with Chroma applied to keyer 3. Keyer 1 and keyer 2 contain my camera sources, with DVE applied to both.

MiniME1 - Standard Green Screen effect, Chroma applied to camera in Keyer 2.

MiniME2 - Video (skype) Box effect with the graphic used for the box pulled from MS4, and Chroma effect applied in keyer 2. I put the source (in this case skype) in Keyer 1 (DVE), so I can make adjustments.

Basically the Ross Carbonite is asking to steal Chromas from other MEs in order to respond to my request for a third chroma. Is the Ross Carbonite limited to only 2 Chroma Key effects spread across multiple MEs.

Thanks,

Ryan

Never mind, I just read in the manual there are 2 Chromas shared throughout the switcher. My bad for posting

Can you make the graphic Video + Alpha so that you can do a linear key?

Yes, I believe that would be a solution. Thank you for your response.
