Hi Steffen,
It is expected that the frameTime returned by GetHardwareReferenceTimestamp will vary. The DeckLink Quad 2 inputs are considered independent of one another, so there will be differences in hardware cycles when IDeckLinkInputCallback::VideoInputFrameArrived callback occurs for each input.
Currently there is no way of synchronising the callbacks to capture at the same hardware time, so some additional setup and coding is required for the application to perform synchronisation (for instance, one solution could be to use timecode).
Kind Regards
