Camera

In the Camera section, special camera behavior settings which are used for virtual studio setups, can be set. Viz IO is used as the studio configuration and calibration tool for enabling connectivity and control between all required studio devices such as cameras, routers, VTRs, video servers, audio mixers and other studio equipment.

Note: Viz Tracking Hub and Studio Manager are the successors of VizIO. VizIO will be deprecated soon, please consider of upgrading your virtual studio installation to Tracking Hub. To enable Tracking Hub, set the flag use_trackinghub to 1, section CAMERA.
