- Should the Black Magic IP4K video card appear as a device in Black Magic nodes? It seems it should, but I don’t want to report a bug until I understand.
Yes, it should — the vuo.blackmagic documentation lists Intensity as one of the supported product lines.
I’d suggest creating a simple test composition that just contains a List Blackmagic Devices node. When you run the composition, is your IP4K listed in either the Input Devices or Output Devices from the node? If you go to Tools > Show Console, do you see any errors, warnings, or other messages about Blackmagic?
It is a bit surprising that Vuo detects your IP4K as a native video device. Do you by any chance have a DAL driver installed in /Library/CoreMediaIO/Plug-Ins/DAL ? If so, try moving it out of that folder, restarting your computer, and running your composition again.
- How does the attached composition need to be edited to provide video delay?
The structure of the composition looks OK based on the composition you got working with non-Blackmagic video. Presumably you’ll want to replace the Receive Live Video with Receive Blackmagic Video once we figure out the problem with your device.
