Special Splittscreen for live production in 16: 9 and 1: 2?

Hello everyone!

I have a task that I unfortunately can not solve adhoc, maybe someone can help me please?

I need the following set-up for a live event on a projector which displays the picture in 16: 9.
I have two sources, a PowerPoint / Keynote (source 16:9) and a recording of the speaker (source 16:9) and they should be displayed in such a splitscreen.

Here is a PowerPoint in 16: 9 and a live video in 1: 2 ??? shown in the split screen.

How can you realize something like that? Is there any "box" there by BlackMagicDesign what can it do?
Or any video card from BlackMagicDesign with which you can mix / splitt two of these SDI and / or HDMI sources?
Or any software that can do this?

Thanks for your help!

Get a 1ME or 2ME switcher. Activate the DVE and crop a 16:9 source to the 1:2 you need..

Make markers for the cameraman on his preview screen so he has a guide where he needs to keep the speaker between..

The powerpoint might be a issue to get left justified.. But depends on how the content is made..

Maybe just go a 2ME and use Supersource to fix that issue.
