Lock Shield

To “lock” Shield to a reference input, we recommend one of the following options:

Fixed Framerate

!This option should be used only, if the GPU is locked to an external house sync,
like with an NVIDIA Quadro SYNC II card.

Enable the option “Use Fixed Frame Rate” and define the frame rate within “Fixed Frame Rate”.

!Make sure that the “Fixed Frame Rate” is equal to the external house sync from the GPU.

Custom TimeStep

This option used an SDI input to “lock” Shield.

*The SDI input can´t be used for any other purposes.
If there is a need to use the same signal within the engine, the signal needs to be splitted to another input connector.

!Make sure that the “Fixed Frame Rate” from above is disabled.

!Make sure that none used SDI output has enabled the “Wait for Sync Event” from below settings.

Before a “Custom TimeStep” can be selected, it needs to be created:

Create a custom TimeStep

Within the content browser a “Blueprint Class” needs to be created.

search for the TimeStep class and select the type matching the SDI capture card.

Select the connected input and configurate this class.

Now this TimeStep class can be used as custom TimeStep provider.

Within the genlock view, the sync can be “reinitialized” and it`s possible to monitor these.
Window -> Developer Tools -> Genlock

Use the SDI output to lock Shield

!Make sure that the “Fixed Frame Rate” from above is disabled.

!Make sure that none custom TimeStep is defined from above settings.

Select ONE used SDI output from the Shield Settings and open these settings.

Enable the checkbox “Wait for Sync Event”

!Make sure that this SDI output card used an external reference and check if the output is locked to it.
