I think there is a problem in vMix with Blackmagic card.
Both in vMix 22 and 23

I am using PC-1 Blackmagic card as an input to vMix
And sending vMix out to Blackmagic card as an external device.
All in 1080 50i

PC-2 SDI in Blackmagic card

The problem is, outputting blackmagic input thru vMix external SDI output
Makes the video a bit soft,
And it is 1 video line lower than it should be.

Compered to blackmagic media express pass thru
Of the same input and output.

On more interesting fact,
The NDI output of the SDI source input from vMix
(Additional NDI Outputs)
Is perfectly fine!

the NDI of the Main output is also soft..
