I’m currently testing latency in a Quadro RTX4000, Quadro Sync, AJA Corvid 44, and Blackmagic DeckLink 8K Pro environment.
I have sync signals on all Quadro, Corvid, and DeckLink, but the difference between the frames shown on the display and the frames of the video output from SDI is not constant.
When I observe it, the delay can be 1-2 frames larger.
What is the solution to keep the delay constant?
I have the same phenomenon with both DeckLink and Corvid. If anything, Corvid is more stable.
