M4 Max Studio and Premier Pro with UltraStudio HD Mini

Hi. Has anyone had any issues with Premiere Pro 2025 not seeing the video connection in premiere's video output prefs to the UltraStudio HD Mini?

This is on a brand new M4 Max Studio - 16 core cpu 40 core Gpu 48gb Ram / 1Tb SSD running 15.4.1. System Report sees the HD Mini.

DaVinci Resolve sees the HD Mini video and audio fine but all Premiere sees is the audio connection - not the video. Therefore unable to preview an output through the HD mini to an external monitor.

My work around is HDMI out of a GRaid drive to 1920x1080 monitor.

I've updated to the latest Desktop Video app / tried re-installing etc. Also did a firmware update on the HD mini. Checked all the extensions and security prefs in apple system settings.

Photo Booth sees the HD Mini - not tried OBS yet but presume it will.

I'm guessing that it's an issue with Adobe's software but interested to see if anyone else has a similar issue. Ran fine on an iMac 2017 on Ventura.

Update: Adobe have said that the DeckLinkTransmit.bundle needs to be in /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore but it isn't and I no longer have an older backup from the previous system to pull it off.

Apparently I’m missing the transmit.bundle file which should be installed into the media core folder in the library. But it’s not being installed properly and I don’t have anywhere else to pull it from?

Solved. Rolled back premiere to 24.0. Reinstalled 14.5 desktop video. Then updated to premiere pro 2025.

Hi-

I'm having the same issue. Did you figure out how to resolve it?

He did. Also posted the solution 2 hrs before you posted this question. Did you try the solution?

Yes. I did the same thing and that did the trick. However, I noticed that the BlackMagic Design Sequence presets have disappeared in the 2025 version of Premiere Pro. They were there in the 2024 version. Any idea about how I can get these back?

I dug it out of the installer package and put it manually in the /Library/Application Support/Adobe/Common/Plug-ins/7.0/MediaCore folder. It's here, if you or anyone needs it. https://we.tl/t-s3k6UJ96OL

Is it a bug in the Desktop Video installer? I think it is
