ATEM Mini Extreme: multiple Upstream Keys on one source

Hi! I'm looking into buying an ATEM Mini Extreme, but I have a very specific need that I haven't seen anyone explicitly state it's capable of. Can more than one upstream key be applied to a single source?

To provide a more specific explanation, here are the inputs I'd have:
- 2x live camera feeds
- 2x overlays with live updating info/data each coming from a separate Windows PC

My desired output is for one of the camera feeds to be the "background", the other camera feed to be floating above it in picture-in-picture, and the data overlay from a Windows PC to be overlaid over both of these.
I'd want two separate output feeds, both with the same two-camera PiP view, each with its own overlay from one of the two Windows PCs.

Is this configuration (or similar) possible with the ATEM Mini Extreme? Hopefully I explained it all clearly enough

To have different overlays on your outputs at the same time you would need a 2 or 4 M/E

AT FIRST .. Atem MINI extreme , have only 2 hdmi outputs .. And U need one for multiviewer ..
And for output 2 different keys , u need more M/Es ..

My thinking if you just want fixed outputs as you describe and no need for a Multiview, it’s possible to have one HDMI output set with program and desired keys. The second HDMI would have Preview set with different keys as you describe. It’s all based on the Key settings. All fixed. But do double check my thinking with your plan.

Thanks for the replies! This is what I thought as well, based on what I've read. We have no need for a multiview, so just having one of the desired views on Program and one on Preview seems like it'd work for us.

I'm more unsure on multiple upstream keyers on the same source. Is this possible? Specifically a picture-in-picture (via DVE) with a live chroma keyed overlay over top of that.

Sometimes it's hard to visualize with text, but maybe this will work for you. You can do the same thing with all unique sources with each of the Program and Preview outputs. So on Program, you may set up a chroma key (Key 1), say camera 1 with camera 3 or media player in the background along with a DVE (Key2) sized and positioned with say camera 5 as input. (All numbers arbitrary to show they can all be different sources). then on Preview you can set up a different chroma key (Key 3) with camera 2 and background (preview bus) as camera 4. Then a different DVE (Key 4) with camera 6 as source. That's. All the keys. Is that what you are interested in?
