Question / Help Elgato Cam Link from BlackMagic image squashed

[brightscreen]

Hello!
I'm using a BM Atem to an Elgato Cam Link to feed my OBS on a MacBook Pro. I have excellent results when I use the Cam Link with inputs from computers running PowerPoint presentations and even through HDMI splitters but the BM Atem image (1080 60i) is coming out squashed vertically. Any ideas? I have gone back and forth with Elgato and since it isn't happening with their "Game Capture" utility they say it is an OBS artifact.
Best,
Roland

...and what happens if you turn off "use preset" and choose another available resolution? I'm guessing it's doing this because you're trying to view a 1080i signal as if it was 720p and it's getting confused.
