DVE Key Combiner
Combine two channels from the same 2D or 3D DVE keyer to make independent keys that can be layered or intersected.
The key combiner allows two independent DVE channels to operate in the same 2D or 3D DVE keyer. These channels can have different video sources and can be moved, cropped, and sized independently of each other. As both channel exist in the same keyer they cannot be transitioned independently and are both transitioned on-air or off-air together.
Combined keys allow you to control how the channels interact with each other. You can control which channel is on top of the other or, in 3D, you can intersect the channels.

Keep the following in mind:
Keep the following in mind when working with the key combiner:
- The key combiner uses both the video and alpha channels of the key. The channel that is on top is routed to the alpha and the channel that is on the bottom is routed to the video. These correspond to the Key Video and Key Alpha outputs.
