This operator will run a tracker from previous keyframe to current frame for all selected markers. Current markers positions are considering initial position guess which could be updated by a tracker for better match. Useful in cases when feature disappears from the frame and then appears again. Usage in this case is the following: - When feature point re-appeared on frame, manully place marker on it. - Use Refine Markers operation (which is in Track panel) to allow tracker to find a better match. Depending on direction of tracking use either Forwards or Backwards refining. It's easy: if trackign happens forwards, use Refine Frowards, otherwise use Refine Backwards :)
