Nitris V7.6 QFE3
 
Background is someone standing outside holding a blank frame.  The inside of the frame is black with 4 tracking points evenly place near each corner.  The clip that goes inside the frame is a container with 4 shots dissolving into one another.  I got this to work with one track where the person holding the frame is moving a bit left and right.  The problem I am having is the next shot I need to track.  The person holding the frame rotates it 90 degrees in the middle of the shot.  The tracker keeps stopping once the rotation begins.  I added a CC to the background to add contrast and managed to finish the track with some stops and starts, however, in the final composite, once the frame gets rotated, the image being composited starts warping and does not spin with the track.  Any help is greatly appreciated.
 
TIA
