Subject: Video Evidence 'Valueless'?

There is a very interesting article in the November issue of Advanced
Imaging magazine.  (Page 59).

The article is about a new computer software app from the British
firm Harlequin called Panoptica.  Panoptica has the ability to
generate full motion sequences on video from just a single still
frame.  It does this seamlessly, and can combine elements from
different images, both still and motion.  Basically it is the
first commercially released example of motion image processing
programs which will allow users to to in motion what has become
standard in still imaging.

  "Central to its capabilities is its ability to extract the camera
  pointing (and therefore motion) characteristics from the original
  sequence by source frame analysis alone.  Panoptica is thus
  largely driven by a reconstruction of the geometric relationships
  between the original camera, and the projection of the frame
  images on its focal plane.

  This information is used to derive a virtual, resolution-independent,
  description of the entire scene originally filmed.

  After this, a virtual camera can traverse the generated model,
  executing entirely new camera moves, at a new focal length,
  optionally different tilt........."

This means that just about any motion sequence could be generated
with this program, and if done properly would be undetectable as
an artificial sequence.
