Blackmagic 4k Extreme - external Key Blacklevel

Hi all,

we use the the Blackmagic 4K Extreme with Fill & Key (HD1080i50) output.
But we have some problems with the blacklevel of the key output.
Did someone know this problem and has a solution?

If we try the "Blackmagic Live Key"-App, it looks good. But not with Ventuz4 :(

Yes there is indeed a Problem with the Blacklevels and the Internal Keying especially with driver version 10.8.4.

The Problem is known to Blackmagic, and they admitted its their issue.
So its more a Driver related problem than a Ventuz Problem.

I am sorry
