One of the most important aspects of using a Video Input in immersive video production is understanding where it exists in space (specifically relative to your tracking system). The simplest setup would include a stationary video input, though MixCast also supports moving cameras which are referred to as ‘Tracked’ as you need to attach a tracked object to the video input to keep its placement in sync.
Though MixCast allows you to manually enter the position and rotation of a video input, the primary method to determine your Video Input’s alignment is to run through MixCast’s Controller Calibration process with that device. You’ll need a VR system connected to the machine, and should recalibrate alignment whenever your Tracking System’s base alignment has changed (such as performing Room Setup).
Note: If you’re using a supported device, MixCast might also be able to use the camera’s IMU sensors to increase your alignment accuracy.
