@Leigh_C Some users testing the ATEM Mini system have found it to be successful with Mac OS using adjusted settings. Please see the comments on this thread for details.
@ruthiae In some cases (as referenced by GoTo users on this thread) the right ATEM settings can achieve broadcast quality on Mac OS. I'm afraid this isn't a set up we directly support right now, but you may find value in the Community discussion around the integration techniques.
AshC You said "It should be in the Audio section of GoToMeeting's desktop settings, though I'm not 100% about Mac yet. The version is 10.15."
Are you talking about GoToMeeting or GoToWebinar?
We are disusing GoToWebinar here, though every time I run a GoToWebinar, the software is labeled on the Mac in the menu to the left of the File menu as GoToMeeting. Ironically, you have to click on "Quit GoToMeeting" in order to quit a GoToWebinar. That's odd.
We made it with obs. It was possible to put the 1080p into a 720p video and we started the virtual cam in obs. That worked very well and we were able to choose the obs camera as webcam.
But the bigger problem was: everytime someone logged into the webinar with a smartphone, the upload of the video went down to 300-1000kbps. Without any smartphone in a session it was around 1800-2500 so the video was a lot cleaner and better without any smartphone in the session.
Our costumer is user of the plus product and is paying 500€ in a month. So i think for that amount of money it should be possible to get a good videoquality. 2500kbps in 720p would be enough when it would be stable. But there is anything that makes trouble when a smartphone is logged into the webinar 😞
Edit.: Mac didnt work for us. Video was cropped (GoTo thought it is a 4:3 format) and the video was mirrored.. But it was possible to choose the Atem as a webcam in 1080p60
Just a workaround that I use.
I have an original Blackmagic Design Web Presenter that solves it for me. I take the audio and video from my ATEM (usually as a single SDI or HDMI feed, though this device can accept audio via XLR and RCA as well) and send it to the Gen 1 Web Presenter. The Web Presenter downsamples to 1280x720, connects as a webcam, and works well. The downsampled full-frame video will usually look superior to higher resolution videos in GTW and will decrease bandwidth requirements. Frequently, the 720p version will outperform the 1080p version on legibility of busy or text-heavy slides.
These first-generation devices have been discontinued, but you can still find them on eBay and other sites for about $150 (on this date).
