Workflow Overview
In this section, we build a complete virtual studio workflow using the nodegraph.
We start by adding the engine and creating the camera and tracked billboard. Then, we add the video input and output resources and configure them according to the hardware setup.
Next, we add the tracking sources for both the camera and the talent. After enabling tracking and network communication, we connect the tracking data to the engine and verify that video and tracking signals are received correctly.
We then prepare the video feed by applying lens undistortion and setting up the studio cyclorama. Based on the studio configuration, we capture a clean plate that will be used for keying. Afterward, lens distortion is applied back to the rendered outputs to match the camera image.
The keying stage is added to separate the talent from the background using the live video feed and the clean plate data. Camera position and rotation controls are exposed to allow manual alignment when needed.
To support talent tracking, position data is connected to the engine and offset controls are added for fine adjustments. This ensures correct placement of the tracked billboard and stable camera behavior.
Finally, the engine render and the keyed talent are composited together. The final result is sent through the mixing stage and routed to the program output, where monitoring is used to confirm the final composition.
