Hi,

I'm using the Intensity Pro 4K under DirectShow. Unfortunately, I can't select the desired video format 2160p29.97 from within the PropertySheet (CLSID_DecklinkVideoCaptureProperties), because it is missing here. Is there a special reason of why you left some formats out? By the way, the DecklinkCapture sample is affected as well.

Software + SDK version is 10.5.1

Thanks,
Rene

Hi Rene,

Generally, the recommended interface to the capture cards is the DeckLink API.

A DirectShow interface is available, but provides a subset of the functionality available from the complete DeckLink API.

Please note that the older, user-space DirectShow filters (DeckLink Video Capture) are deprecated in favour of the WDM filters (Blackmagic WDM Capture).

The WDM filters added support for 4K modes in Desktop Video 10.5+.

Hope that helps,

Hello Nicholas,

I don't really know why I overlooked the WDM filter, but it does the business.

Thank you very much!
