Due to a driver issue it is currently not possible to use the “Buffered Input” setting with video devices from Blackmagic Design. We are working with Blackmagic Design to resolve the issue. Video devices from AJA (on INTEL or Apple silicon) are not affected.
When using a video device from Blackmagic Design under macOS Catalina (10.15.7) on Intel-based Macs, you MUST run Just Out and Just Control on separate machines. Otherwise audio dropouts will occur while generating the Poster Frames or while working on the Finder level.
Blackmagic Desktop Video Setup: Please do not give your BMD device which is used for playout a name using the text field “Label” under Product Notes. Doing so will prevent just:out from starting properly or crash it during start up.
Using an Apple silicon-based Mac for the machine running Just Out, the AJA driver version 16.2.x or higher is recommended.
The HDMI output of the Mac can NOT be used for the broadcast output signal. Please ensure that one of the dedicated video devices listed below is used.
