class unreal.AjaCustomTimeStep(outer=None, name='None')

Bases: unreal.GenlockedCustomTimeStep

Control the Engine TimeStep via the AJA card. When the signal is lost in the editor (not in PIE), the CustomTimeStep will try to re-synchronize every second.

C++ Source:

  • Plugin: AjaMedia

  • Module: AjaMedia

  • File: AjaCustomTimeStep.h

Editor Properties: (see get_editor_property/set_editor_property)

  • enable_overrun_detection (bool): [Read-Write] Enable mechanism to detect Engine loop overrunning the source

  • media_configuration (MediaIOConfiguration): [Read-Write] The device, port and video settings that correspond to where the Genlock signal will be coming from

  • timecode_format (MediaIOTimecodeFormat): [Read-Write] The type of Timecode to read from SDI stream.

  • use_reference_in (bool): [Read-Write] If true, the Engine will wait for a signal coming in from the Reference In pin. It will also configure the card Genlock mode and configure the selected Media Port as an output.

  • wait_for_frame_to_be_ready (bool): [Read-Write] If true, the Engine will wait for the frame to be read. This will introduce random latency (the time it takes to read a frame). Use this option when you want to synchronize the engine with the incoming frame and discard the buffered frames. note: If false, there is no guarantee that the incoming frame will be ready since it takes some time to read a frame. note: This will not work as intended with interlaced transport because both fields are processed at the same time.
