Question / Help Red and blue vertical stripes in recorded video (but not in obs)

[ratatat]

Hi,

I am recording video from 4 HDMI sources using a magewell video capture card. When I look at the videos on the screen in obs they seem fine, but my recording has vertical red-ish and blue-ish stripes. Is this something in the recording settings maybe?
