Hey, so I'm setting up with OBS for the first time and I've got a video feed coming from a Canon XH-A1 sending full 1920x1080 signal via firewire to my iMac. But for some reason, no matter what settings I seem to try in OBS, the image is showing up as a squished 4:3. It also looks that way on the fb stream from OBS. Appreciate any help you can give!
