Changing the Framerate of a Virtual Production Stage using Ross SPG

Introduction:
This guide will walk you through the process of changing the framerate of a Virtual Production stage using a Ross Sync Pulse Generator (SPG). The Ross SPG is responsible for synchronizing multiple render nodes together and generating timecode in a Virtual Production environment.

Prerequisites:

Ross Dashboard software installed on your computer
Access to the Ross SPG’s network

Step 1: Configure your computer’s IP address

To access the Ross SPG, you need to set your computer’s IP address within the same range as the Ross SPG. Configure your computer’s IP address as 192.168.1.XXX, where XXX is a unique number between 1 and 254.

Step 2: Access the Ross Dashboard

Open the Ross Dashboard software on your computer. This will allow you to connect to the Ross SPG and view the current configuration settings.

Step 3: Locate the BNC clock settings

In the Ross Dashboard, you will see a list of BNC clock settings corresponding to different outputs on the SPG. The first Tri-sync output is labeled as “2,” which is routed to a distribution amplifier (DA) responsible for synchronizing the entire volume.

Step 4: Change the framerate

Select the BNC clock labeled “2” and change the framerate to your desired setting. This will update the Tri-sync output to the new framerate, effectively changing the overall framerate of the Virtual Production stage.

Step 5: Set the framerate of timecode on the SPG

In the Ross Dashboard, navigate to the timecode settings section. Locate the current timecode framerate and change it to match the new framerate you set in Step 4. This will ensure that the timecode is synchronized with the updated framerate of the Virtual Production stage.

Conclusion:
By following the steps outlined above, you can successfully change the framerate and timecode settings of a Virtual Production stage using a Ross SPG. Remember to ensure your computer’s IP address is within the same range as the Ross SPG and adjust the Tri-sync output and timecode settings accordingly to achieve the desired framerate.
