Then once you get OBS back to seeing your feed, start bringing back online your other USB devices one at a time. Also isolate it to a high speed USB port (preferrably a thunderbolt USB-C port).

Try to turn off/disable all USB ports, crank back up your ATEM and let it be the sole device to use USB. ? Perhaps OBS is more demanding for the full fps and quality, and other apps are less demanding. For some reason, some perfect storm order of initializing happened today, that perhaps got the ATEM a different place in the hub? What I don't understand is that I could see the BlackMagic device in the local Camera application crystal clear (AND at one point I plugged the ATEM directly into another USB A port (though not a 5Gbps one, vs the 10 port USB hub I have gets a 5Gbps port on my laptop). I added Stream Deck about 2 weeks ago and all was fine. That hub is plugged into a 5Gbps port and most everything is simple devices like keyboards, mice, BQ SW320 monitors (for weekly screen calibration and putting new hardware icc files on the monitors). Everything was fine for days with 9 USB devices. Where it was connected was a 10 port powered USB 3.1 hub. I even plugged it straight into one of my two USB-C ports (reluctantly) to make sure it has priority and enough speed. When I unplug all USB devices and plug in the ATEM first, I can then see it in OBS now. Looks like it ended being a major USB issue. EVERYTHING worked just fine last night and then the next day it quits RIGHT before the meeting.įirst, this issue was between ATEM and OBS Studio. I ended up having to use the Sony Imaging Edge web cam option, but couldn't use my other 3 cameras or any of my fancy scenes I spent tons of time setting up. I have tons of scene's and Stream Deck multi-actions, and hot keys all set up for OBS and it failed me at the absolute worst time today for a big customer video conference. It just plain doesn't work, all I get when I choose the Black Magic ATEM is black nothing.

Yes, I went into to advanced settings for the camera and didn't see any other app that currently was using the ATEM.

Yes, I tried creating a new Scene with nothing in it but a basic Video Capture pointed at the Black Magic ATEM.

Yes, I tried launching OBS Studio as Admin.

Yes, I have uninstalled OBS Studio and re-installed the latest.Yes, I have uninstalled ATEM mini and re-installed the latest.Yes, the ATEM mini camera feed works (I can see it in the Camera app and other tools NO PROB).Yes, I have already looked at web security.
