Shogun Live lets you link a calibrated SDI or Vicon Vue video reference camera to a rigid tracking object. This enables the video camera to be tracked, providing real-time 3D overlay in Shogun Live while the camera is moving and enabling the animation to be captured to the MCP.

To link a calibrated video camera and a rigid tracking object:

Create the object (normally a tracking crown or set of markers attached to the camera) in the usual way:
1. In the 3D View, select the relevant markers.
2. In the Tracking panel, in the Prop field, enter a name for the object and click Create.
3. If you want to use the object tracker (see Understand object tracking in Shogun Live), in the Tracking panel, on the Properties tab, ensure the new object is selected and in its Properties, ensure Track with ObjectTracker is selected.
In either the Workspace view pane or the System tree, Ctrl-click to select a calibrated video camera.
In the Tracking panel, on the Setup tab under Video Camera Tracking, click Link Camera.

The button text changes to display identifying information for the linked camera and the bone for the prop moves to the video camera's optical center, aligned with the video camera's coordinate system.

You can now move the camera while maintaining the 3D overlay, and you can see the camera moving in the 3D View and Cameras view.

To detach a video camera and rigid tracking object:

At the top of the Tracking panel, select the prop that you want to unlink from the video camera.
Under Video Camera Tracking, click Unlink.

The prop and camera are unlinked, and no longer move together. The prop origin remains at the video camera's optical center, and the video camera remains in its last position.

If you recalibrate the linked video camera, for example, following a zoom lens or tracking crown location change, the linked prop is also automatically updated so that the correct calibrated nodal point is maintained.

After you have captured a scene with linked video cameras, you can load the MCP into Shogun Post. The linked video cameras display the same animation in Post, with a key per frame for translation and rotation.
