‌Preparation for Two-Dimensional Tracking

We’re ready to begin tracking the actual performance footage. Open the final calibration scene file. Open the 3-D panel . For each camera, select the camera in the select-by-name dropdown list. Then hit Blast and answer yes to store the field of view data as well. Then, hit Reset twice, answering yes to remove keys from the field of view track also. The result of this little dance is to take the solved camera paths (as modified by the script), and make them the initial position and orientation for each camera, with no animation (since they aren’t actually moving).

Next, replace the shot for each camera with LeftFaceSeq and RightFaceSeq.

Again, these shots have been cropped based on the light flashes, which would normally be removed completely. Set the End Frame for each shot to its maximum possible. If necessary, use an animated ROI on the Imaging Preprocessor panel so that you can keep both shots in RAM simultaneously. Hit Control-A and delete to delete all the old trackers. Set each Lens to Known to lock the field of view, and set the solving mode of each camera to Disabled, since the cameras are fixed at their calibrated locations.

We need a placeholder object to hold all the individual trackers. Create a moving object, Object01, for Camera01, then a moving object, Object02, for Camera02. On the Solving Panel, set Object01 and Object02 to the Individual mocap solving mode, and set the synchronization mode right below that.
