Synchronization of the video images can be checked after the trial has been analyzed fully. For each view, the 2D representation of the skeleton in that view is compared to the 3D skeleton computed from all views. If the alignment for a given view can be improved by shifting its video sequence forward or backward in time, this frame offset is reported in the dialog. You can then choose to correct the synchronization by applying these offsets to the out-of-sync views and clearing the entire analysis.

Note: This command does not work on trials with minimal motion, such as static trials. Additionally, if there is relatively little motion of all tracked people in a particular view, that view may be detected as out of sync with the others when it is not. For example, if the person is far from a camera (small image) and moving directly towards or away from it, there may be minimal motion of the person within the video image. Another example is part of the person being stationary during the trial and the camera capturing only the stationary part. Please check for false positives like these before correcting the synchronization.
