3.27 Capture Pass Through Mode

enum BMDDeckLinkCapturePassthroughMode

BMDDeckLinkCapturePassthroughMode enumerates the behavior of the full-duplex output when capturing an incoming signal and playback is disabled.

• bmdDeckLinkCapturePassthroughModeDisabled

  enumerator bmdDeckLinkCapturePassthroughModeDisabled
  

  In disabled mode the video input is not displayed out the monitoring outputs, which instead display black frames or the last frame played, dependant on the configuration of the Idle Output setting (see BMDIdleVideoOutputOperation).

• bmdDeckLinkCapturePassthroughModeDirect

  enumerator bmdDeckLinkCapturePassthroughModeDirect
  

  In direct mode the monitoring video output is directly electrically connected to the video input.

• bmdDeckLinkCapturePassthroughModeCleanSwitch

  enumerator bmdDeckLinkCapturePassthroughModeCleanSwitch
  

  In clean switch mode, the captured video is played back out the monitoring outputs allowing a clean switch between monitoring and playback if the video modes are compatible. The monitoring output signal is affected by the options specified on capture and some latency is introduced between capture and monitoring.
