Video capture show pixelation in some dark regions

PostMon Oct 30, 2017 9:09 pm

Hello, unfortunately I'm not a video expert so some of the terminology is foreign to me. I've surfed around the internet for a better understanding but just not getting it. I have a customer who is playing a DVD as a live capture source into the HDMI input, but the video is showing a lot of strange color effects
which looks like this:

Could someone please indicate to me what could be causing this effect? Can this be "tuned" out by adjusting the NVidia graphic card settings or the video source. Let me know if you need more detail.

My capture card is Decklink Studio 4K using the latest Desktop utility 10.9.7. The desktop utility show a clean video, but our application using the Decklink SDK show this image attached.

Please help! Thanks!
