I want to use the internal keyer of the Decklink 8K Pro to place an overlay on a live video image. Different input video formats should be supported and the input video properties (resolution, refresh rate, color coding, ...) should not be changed.
I set the output video mode based on the detected input video mode. This ensures that the resolution and refresh rate are correct. However, if the input signal has a BT.2020 color space, the color space is converted to BT.709 after keying. (If I have BT.709 at the input, the output is BT.709 as expected)
How can I control the color space on the output pin of the Decklink 8K Pro?
Here a screenshot of the DeviceStatusCSharp.exe from the Decklink SDK examples showing the difference between input and output signal:
