Camera track and blackmagic card capture

[alverman]

Good evening,
I'm trying the camera tracking on my wd pro in 1100.
On pc I have a capture card blackmagic intensity pro which is connected via HDMI, a normal camera.
Now using the camera tracking and selecting the blackmagic wdm capture everything I see is black.
The card has the driver and finished it with other programs work. what is the problem?
Thanks for your ad use.
