Nuendo not starting witk Blackmagic intensity 4k

We are trying to get Nuendo running with the Blackmagic intensity Pro 4k PCI/E-card.

When we start Nuendo it freezes on the loading screen where it says on the bottom “Video Devices” (in german it is “Video-Geräte”, so i guess the english version is video devices).

We tried several different computers and tried with Nuendo 7,8 and 10. Sometimes it works after a PC-restart and Nuendo launches, but most times it freezes.

The Intensity 4k card on itself works with other programs like the blackmagic video editor.

We changed our systems back to the “old” HD intensity card and it works like a charm, so the problem seems to be Nuendo in combination with the Intensity 4k.

Is there a known issue with Nuendo and the Blackmagic Intensity 4k or any hints on how to solve this?

We are running on Windows 10 with the newest Nuendo Updates and Blackmagic drivers.

Unfortunately Nuendo cannot output 4k video although it will load into a project. A long standing bug, even in v13.
You have to convert it to 1080p HD or 720p.

I also use Intensity 4K on a Nuendo 11 video slave using VST system link. Very snappy but alas not 4k capable.

Thank you so much for you reply!!

As you say, 4k files will import but when I set the intensity card to 4k I get an image that fills about 2/3rds of the screen on playback

This is unbelievable, and really disappointing! Hoping this will be fixed soon.

This is how the 4k playback looks out of Nuendo 13 Dropbox

and this ia s 4k file out of Davinci resolve Dropbox

You mean specifically through a Blackmagic device?

I just output a 3840x1600 (2.4:1) and a 3840x2160 from Resolve (source was 1920:800, also 2.4:1) as DNxHR and it both imports and displays on screen. When I set to full screen on my 21:9 3440x1440 monitor I get some borders on all sides using the first file, which I guess is a bit odd since I would expect the image to fill at least vertically… and when I display the 2160p version on my 16:10 monitor at fullscreen I again get some borders, but not much.

Bottom line is that the image is centered in both scenarios and fills nearly all of the screen. This is all coming out of a Radeon VII, not a dedicated playback device.

So what resolutions are you using and what codec / container?

I’m using the Blackmagic DeckLink Mini Monitor 4K.
The video file is an H264 mp4 and an H264 mov. The resolution is 3840 x 2160.
My monitor says it’s receiving 3840 x 2160 but the image size is reduced.
The same files fill the screen perfectly when playing out via the same DeckLink 4k card when using Blackmagic Davinci Resolve and Blackmagic Media Express
