Bob, this can be confusing at first. The manual explains it a little bit but actually pushing the buttons helps see it through. (Page 84, see 'Next Transition' section.)
With the ATEM Sofware Control, the Upstream keyers will transition on and off using the 'CUT' or 'AUTO' buttons (hence the 'Next Transition' section where the key buttons are.)
Let's say Input 1 is a person on camera, or a playback deck. Make that live on the Program bus.
Let's say Camera 2 is your chroma key person. In the Palettes under Upstream Key 1, choose the Chroma tab, select Camera 2 as the Fill Source and adjust your key settings.
On the Preview bus, select the input you want as the 'background' for the chroma key, such as a still loaded in Media Player 1. You will see this on the Preview.
Now go to the 'Next Transition' section and select 'KEY 1'. You will now see your Chroma Key person on top of the background from Media Player 1.
Now if you press 'CUT' or 'AUTO', the switcher will transition to exactly what you see on the Preview. You will also notice that the 'ON AIR' switch above 'KEY 1' is red, meaning the key is on. Now you can cut back and forth.
Now transition back to Input 1. Let's turn off the 'BKGD' button in the 'Next Transition' section. You will see that KEY 1 is now keying on top of Input 1, not the Background from the Preview bus. Now if you press 'CUT' or 'AUTO', it will bring your key on top of Input 1.
You can also have other keyers coming on at the same time. Let's say Upstream Key 2 has a Lower Third loaded. Then with 'KEY 1' and 'KEY 2' buttons selected, both keyers will come on when you press 'CUT' or 'AUTO'.
(If using the Television Studio HD, you only have 1 Upstream keyer. But you can have a Downstream keyer come on at the same time by pressing the 'Tie' button.)
To make this easier, you can program Macro buttons to set up your keyers for you in one fail swoop.
I hope this helps. Let me know if you need further clarification.
