Question / Help 1080p video on Logitech BRIO and C920

[theking2]

Hi!
I got two cameras hooked up to the same system. A Logitech BRIO and a Logitech Web C920 . Both are supposed to be able to do a 1080p 30FPS video.
In OBS I get that working perfectly for the BRIO but the C920 does what seems to be a 5FPS max. on 1920x1080 onlye when I cut back to 1280x720 I get some fluid (10fps?) video . Windows Camera app has no problem displaying 1080p,30fps vid. What could be the cause?

Ok, I thought I iterated through all resolution, frame rate, and format options, but I didn't.
It seems that the OBS is doing a perfect 1080p, 30FPS when I swtich the video format to MJPEG. When I switch to MJPEG I get a perfect fluid video recording.
