Black Screen *Urgent*

Hey guys,
I'm new to OBS software and I have a problem - I have hired a ATEM Mini to feed 4 cameras (2x dslrs, drone and cinema grade video camera) and audio via rca to 1/8, into my mac to stream through the OBS software, but when I select the Blackmagic ATEM Mini option as a video capture device, no picture is feeding through and it's just a black screen. However if I select my webcam on my mac the picture from that pops up immediately. We plugged in a monitor to the ATEM Mini and could see each picture from the cameras so we know there isn't a problem with the device. For some reason the software isn't getting the picture when selected. How can I fix this? Thank you!

I have the same problem. No solution yet. I am adding the ATEM Mini video as a Video Capture Device and "Blackmagic Design" appears under the Device properties. I click OK and get a black screen. I can see the ATEM mini outputs (3 cameras) on the preview screen on another monitor, so I think that the ATEM Mini is working OK. I am using the ATEM Mini in Program mode. This was just working a day before. I can't figure out what I may have done to generate this BSOD!

I was able to resolve this error (at least for now) by installing the latest ATEM Mini firmware update, v8.4. OBS now shows the video stream from the ATEM Mini as expected.

I'm encountering the same issue. I set up my ATEM Mini with a fresh install of OBS, and everything was just fine. Able to see video preview and use the ATEM software control software to switch between sources. While configuring audio settings in OBS the video signal coming from the ATEM mini just stopped and I have a black screen no matter what I do.

ATEM Software Control software version 8.4
OBS version 25.0.8 (64-bit)
Windows 10 OS build 19041.450 (version 2004)

I will try to uninstall/reinstall OBS but I'm not sure if that will fix the issue.

Same problem here! Installed latest software. Worked yesterday and today doesn't work. Worked last week, but the week before that it didn't. It is hit or miss with ATEM Mini and OBS. The ATEM Mini works fine with all other software. It just doesn't work properly in OBS. There's a bug in OBS I believe.

Same thing with my setup...
Here is what I have checked:
  1. already looked at camera security (I even tried turning on and back off)
  2. the ATEM mini camera feed works (I can see it in the Camera app and other tools NO PROB)
  3. I have uninstalled ATEM mini and re-installed the latest
  4. I have uninstalled OBS Studio and re-installed the latest
  5. I ran a fresh Windows Update
  6. I tried launching OBS Studio as Admin (and ATEM)
  7. I tried creating a new Scene with nothing in it but a basic Video Capture pointed at the Black Magic ATEM
  8. I went into to advanced settings for the camera and didn't see any other app that currently was using the ATEM
  9. rebooted a couple of times unplugging, replugging
  10. Tried different USB ports (but like I said, I can use the ATEM web camera in any other tool, just not OBS)
  11. Heck, I even completely removed StreamDeck and OBS Web Hooks
I have too much time into scenes and stream deck multi-actions to use something else. Any ideas? Greatly appreciate it

First, this issue was between ATEM and OBS Studio...
Looks like it ended being a major USB issue. When I unplug all USB devices and plug in the ATEM first, I can then see it in OBS now. I even plugged it straight into one of my two USB-C ports (reluctantly) to make sure it has priority and enough speed. Where it was connected was a 10 port powered USB 3.1 hub. Everything was fine for days with 9 USB devices. 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). I added Stream Deck about 2 weeks ago and all was fine. 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). It was only OBS that couldn't use it.

?? Perhaps OBS is more demanding for the full fps and quality, and other apps are less demanding.
No clue, but my issue was a USB issue.

If you suspect a USB issue. Try to turn off/disable all USB ports, crank back up your ATEM and let it be the sole device to use USB. Also isolate it to a high speed USB port (preferrably a thunderbolt USB-C port). Then once you get OBS back to seeing your feed, start bringing back online your other USB devices one at a time.

other solutions that didn't work for me, but might for you (good troubleshooting info, is to see if you can see your webcam in another app or not before beginning):
  1. restart OBS after making sure all video capture sources are set to deactivate if not in use
  2. uninstall/reinstall the latest OBS and ATEM software (and stream deck and obs webhooks if you use those)
  3. run windows update and reboot if found any
  4. in your graphic settings (in Display Settings), make sure it is on Classic app and then browse for the OBS executable and set graphic specifications to "power saving"
  5. try removing all OBS scenes (back them up) and creating a single simple scene with a video capture source for the ATEM
  6. see if any other app is using the ATEM web camera (go to Settings | Privacy | Camera and see if any listed app says "currently in use" if so, kill the app)
  7. if you suspect #6 is lying and another app is actually using the webcam, use the free utility from Microsoft called "Process Explorer Search". First go to device manager and go to properties on your webcam, then Details, and choose the property "Physical Device Object name" and copy the value (this is the physical device object name for your ATEM). Switch back to the Process Explorer Search, and do a Find on a paste of the object name. It is possible that a local app has the webcam and even Microsoft's camera settings don't list it.
  8. Try another USB port/cable
  9. worst case, try what I did and turn off all USB ports, plug your ATEM into a high speed port all by itself, then check OBS to see if it is now happy with your ATEM feed, then bring the rest of your USB devices up one at a time.

I hope this helps someone else, because I did NOT see this solution any where else.

Any definitive solves to this issue yet? I have 2 black magics running through OBS Windows 10, 1 of them the cameras are working fine, the other is just getting blank screens. Yesterday, all were fine. Any help would be greatly appreciated!

Found out my issue was after updating Windows PC the decklink mini recorder firmware had reverted back to SDI when I am using HDMI. Switched & fixed. Its the stupid things sometimes!

I found a different solution that worked for me but it is not clear what exactly the problem is, it appears to be an OBS software bug.
I go to the property of the video capture device with 'Blackmagic design' selected as input device. All parameters seems ok and with Rsolution/FPS Type 'Device Default' and yet everything is black. How do I fix it? I click on the 'Defaults' button on the bottom left. What it's strange is that no parameters get changed everything remains the same and yet it starts working and the video from the AETM emini Pro starts showing up on the OBS. I got crazy on this but it seems to be the issue.

Has anyone come up with a solution to this problem??? Works one day, doesn't the next. I know it is a setting because a friend of mind figured it out but OF COURSE, I didn't write it down, thinking it wouldn't happen again. I have searched and I have contacted ATEM support (no response after a week). If anyone knows the answer, please reach out. Thanks a million!

This may not have anything to do with your issues, but when the source shows up blank in OBS I click on it and reset the size. It usually works. Right click on the source-scroll down to transform-choose fit to screen. Good luck!

To get the ATEM working properly and consistently I use the ATEM Software Control Application.
  1. Click the cog in the lower left corner to get to the setup screen. (This is not the same as "Preferences" in the app menus).
  2. Set the video standard to something that is sensible with regards to your input devices and cameras, as well as your intended output.

As silly as it makes me seem, this was my issue.

I thought I wasn't getting any signal out of the composite input.

Backstory: Months ago, I had installed and added the Blackmagic Intensity Pro 4K to a scene in OBS, I had named it 'Intensity' and named the scene 'Digitizing'. It had always worked perfectly. I digitized tapes for folks, captured sources from it during streaming, etc etc etc. Life was good.
I had forgotten about this 'scene' for months, and when I finally started OBS up again and went to create a new scene for digitizing, I didn't think about it and created a new Blackmagic Device, named differently (I think I named it 'Intensity Pro 4K' this time). This just got me a black screen and no sound regardless of what video or audio options I chose.

So at this point, freaking out, I thought my composite input (through the breakout cable) was shot. But I hooked up an HDMI monitor to the HDMI output from the Intensity, and the RCA input showed right up on the HDMI monitor output in all its glory...but it STILL wasn't showing up in OBS!

Side note, at this point I discovered that Blackmagic's 'Media Express' program DID see the feed and get the audio. Although this is a potential workaround for digitizing, it exports video files uncompressed and they grow freaking huge. A 45 minute video I recorded was more than 300GB. Too much, for gods sake. Back to figuring out OBS.

Turns out, I was giving myself nights of stress for nothing...when I finally was just clicking around out of some form of desperation, I went back to my old scenes, and when I clicked on one of them, 'Digitizing', the video and audio came right up. I was shocked, but it makes sense with how OBS organizes their input devices...I guess. I guess you don't want the same feed going to multiple sources for conflict reasons? Maybe...?

So basically, to any who haven't checked yet...CHECK if you previously added it already as a different name in a different scene.

Rant over.
