The RELICT HOMINOID INQUIRY 2:41-80 (2013) Research Article ANALYSIS INTEGRITY OF THE PATTERSON-GIMLIN FILM IMAGE Bill Munns1*, Jeff Meldrum2 1Blue Jay, CA 92317 2Department of Biological Sciences, Idaho State University, 921 S. 8th Ave, Pocatello, ID 83209 ABSTRACT. The Patterson-Gimlin Film (PGF), which depicts a walking figure suggestive of a cryptid hominoid species known as sasquatch (or Bigfoot), has been studied and debated since its filming in 1967. One issue not analyzed conclusively is the suspicion that the film itself has been somehow tampered with or otherwise edited to hide data that may point to a hoax. The integrity and quality of the film image have also been challenged and characterized as unreliable. A comprehensive study of these issues of contention has determined that the film was not altered or otherwise tampered with for deceptive intent, and that the image quality is sufficient for factual analysis of the nature of the subject as depicted.

What is commonly referred A third type of cut is an overlap cut, so one to as “splicing” is physically joining two piece of film overlaps the previous piece, and separate pieces of film so they will run provides a surface for gluing the two pieces continuously through a projector or laboratory together, or hot splicing them. printer. “Editing” is the general practice of A fourth option is a diagonal cut, but this is making physical cuts in a film, to separate the uncommon for segments with pictures because desired footage from unwanted footage (called the cut goes through the picture of both “outtakes”), and then assembling the desired segments being joined and may show on footage in a chosen sequence, by a given projection and viewing. The diagonal cut is splicing technique. One may splice without actually intended to cut audio magnetic film or editing, as in the example of using 50‘ tape stock1 because a true horizontal cut tends magazine loads of film, and once they are to produce an audible “pop” at the edit, while processed, the lab may splice several such 50‘ a diagonal cut does not.
