Using Proclaim to send Lower Thirds to ATEM Mini

Does anyone have any experience using Proclaim with the Atom Mini Pro?

I want to be able to send lower thirds to the livestream via proclaim, but am having a tough time figuring it out.

We currently use OBS and send lower thirds there via the NDI plugin, but would like to switch to the ATEM so as to relieve our computer a little bit.

I don’t have any experience with AMP, but do this every week using a virtual display in Proclaim. I grab the display using OBS and it works great.

I don't visit the forums often, but hopefully this helps. We send 3 of the 5 outputs we have Proclaim create from our PC into our ATEM via HDMI. One of them is a 'virtual screen' for overlays that goes into the Upstream Key (USK) and sits on top of the program for most of the service. Most of the time it is simply blank/empty. Any slides the house sees that have info that we want the viewers to also see is given a different look on that virtual screen.

In Settings>Display, in the Output section (scroll past virtual screens), after clicking on the gear icon for that output, we've set the Output Transparency Color to green. In the ATEM, the USK is set to Chroma Key to make anything green on the screen transparent.

Previously, we used the Downstream Key (DSK) for the overlay, which is strictly a LUMAKEY keyer, meaning as colors get closer to black, the more transparent they are. In that case you would set the Output Transparency Color in Proclaim to black. We did this to free up the USK since the DSK cannot be cropped or resized and we wanted the little 'amen' and other things that Proclaim pops up to show in the stream whenever they are used. I mention this because your graphics may look good on the DSK, such as lyrics in all caps white text over a camera in a darker room that I see many churches use.

We found we didn't use the USK as much and the graphic styles we wanted to use looked much better using the USK.
