Thanks for the reply! :-) My request/question is not strictly related to decklink but capturing in general; The ability to set the start tc when the first frame is captured from any capture device. The method should not be depending on incoming tc signals from external devices but rather rely on the PC clock to determine the "exact" capture time of the first frame. If it's feasable.
