Blackmagic Forum

I have been using Blackmagic UltraStudio Mini for webinars and video conferencing. It is connected to iMac through thunderbolt cable.

Problem is that almost daily, I cannot find the video source in any of the applications that should see it: QuickTime/Google Meet/Zoom/... When I detach the thunderbolt cable wait for 15 seconds or so and plug it back, computer again recognizes the video source.

I have purchased total of three identical UltraStudio Mini recorders and have been using these with a handful of different computers. All behave the same: one cannot rely on recorder being available without restarting it.

Is there are way to avoid this or should I switch to different brand?

What Mac / Version of OSX are you using? And do you have the latest version of the Desktop Video utility installed? As I have a few UltraStudio Mini's and they work fine for me with Skype. For Zoom you need to unsign the app if you are on the latest version.

My BM Mini Recorder doesn't show up in Skype as a possible source. My ATEM mini however does. The mini-recorder works with zoom (after I unsigned the app). But for some reason Skype won't see it. Anyone have luck getting Skype to see the mini recorder. I'm using the latest versions of Desktop Video and Skype on a MacMini. Thanks.

Gave up with Blackmagic UltraStudio Mini Recorder, it was just too unreliable.

Replaced it with a $17 HDMI-USB converter (generic one listed as "Audio Video Capture Cards HDMI to USB HDMI Video Capture, Full HD 1080p USB 2.0 Record via DSLR Camcorder Action Cam, Facebook Portal TV Recorder, Live Broadcasting" on Amazon under brand "Kedok"). Have not used it for long yet, but this far seems to be working well.
