Kitchen of the Roman villa at Borg

This panorama has been created from a video clip by the program Microsoft ICE. In the second part of this clip a walking woman is visible but in the panorama this woman is not visible anymore! On the basis of which properties of the video clip ICE the woman has omitted in the panorama photo, is not yet clear to me. Since this video clip was not recorded to create a panorama from it, the video frames are shifted vertically. Video clip at http://www.flickr.com/photos/janbruijns/
