General

• Depending on your tracking system, a zero point is required. This marks a special location in your studio defining the start- or reference point. The design of your set (Viz Scene) and the calibration relays on this location; therefore, clearly mark it.

• Make sure you use correct units during your set design. This makes it much more easier to match your set later on.

• The Studio Manager is mainly used to configure and setup your virtual set. During production this application is not needed and should be closed. Only Tracking Hub needs to be running.

Tracking

Lenses

• Every Lensfile is unique. It is highly recommended to calibrate each lens on the mounted final camera rig. Even if you have an existing lens file available, it might not be sufficient to use this one for another lens of the same type.

Delay

• To get a precise match between real live video and the Engine rendering, the tracking data has to be delayed properly to react within the same field. This can be done for each parameter individually or, in most cases, is handled with the Overall Delay on the camera rig node.

• Adjusting the delay can be easily achived by making quick changes in camera movement to see if the tracked graphic starts before the video signal or if its stops after it. Best practice here is to start with a high delay and decrease it slowly until both layers match perfectly while paning the camera left and right. Once this fits, check the other parameters. In some cases zoom and focus need a different delay which will be added / substracted from the overall delay by adjusting the specific delay of these parameters seperately.

Chroma Keying

Make sure your lighting conditions are the best ones you can achieve. Optimal chroma keying results depend strongly on the good quality of both cyc and homogeneous light.
