3D SDI output on DeckLink 8K Pro

PostThu Mar 05, 2020 11:15 am

Following the TestPattern sample, we detect that none of the display modes supports 3d by checking the flag: m_displayMode->GetFlags() & bmdDisplayModeSupports3D.

First question:
Does the DeckLink 8K Pro support SDI 3D output ?

Second question:
If 3D is supported, how do we activate it on a particular video mode ?
From the DeviceConfiguration sample I tried setting it as default video output mode flag:
iVideoOutputModeFlags | bmdVideoOutputDualStream3D);
But all video modes report the bmdDisplayModeSupports3D as false.

Thanks in advance for your time and support.

Hi Bernard,

Yes 3D output is supported by DeckLink 8K Pro, you can check video mode support with either:
  • IDeckLinkOutput::DoesSupportVideoMode, with supported video mode flag bmdSupportedVideoModeDualStream3D
  • With DeviceList SDK sample
Ensure that you have enabled a profile which 3D is support (dual-link or quad-link modes)

To activate, you need to call IDeckLinkOutput::EnableVideoOutput with output video flags including bmdVideoOutputDualStream3D. You will need to schedule video frames that implement IDeckLinkVideoFrame3DExtensions. Refer to the SignalGenerator/TestPattern SDK sample for example how to create a class that implements IDeckLinkVideoFrame and IDeckLinkVideoFrame3DExtensions.
