I am trying to track / stabilize vertical video and not getting a good result

Currently Lock and Load and SliceX / TrackX / DriveX do not work correctly with footage from a iPhone shot in vertical mode.  In order to use it with these products you will have to take the video footage into a standard horizontal project, place it so it has black on both sides then export as a 16:9 clip.  When you bring that clip in you can then use the above products on it.
