Ultrastudio 4K Mini works in Resolve, not in After Effects

Hi all,

new Mac Studio M3, and I have a bit of trouble setting it all up. My Ultrastudio 4K Mini works in Resolve, but it does not appear in After Effects or Premiere. In Audio Hardware, I can select the Ultrastudio for output, but for video preview, the Ultrastudio does not show up in Mercury Transmit. I've done all the usual uninstall-reinstall stuff.
BMD Desktop Video version 14.5, but downgrading does not help
After Effects, Premiere versions 2025, but downgrading does not help.

What am I missing?

Tx,
Wim

Hi,

I am having the same Problem on the same machine (M3 Ultra). I reinstellen several times and it just does not show up in Adobe Apps. Davinci is working fine and in the Desktop Video settings everything behaves normal. It seems to be an issue related to the installation for Adobe Produkts ?!

Happy to hear about some kind of fix

Hi Stefan and others,

I finally found a solution: there needs to be a file called 'DeckLinkTransmit.bundle' in /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore/ Once the file is there, the decklink device shows up in Adobe apps. The file is buried deep in the Desktop Video Installer and somehow it does not get copied to the right location. Here's the file: https://we.tl/t-s3k6UJ96OL.

Did you toggle the external display with the forward slash key on the numeric keyboard?
