>>You forgot to mention that anyone wanting to actually use that trick to try and locate a difference would have to dupe 2 prints on the SAME projector and without moving the camera (on a tripod of course). <<Brad: Actually, I was thinking of telecine-transferred prints. With a good program like Media Studio, you only have to make slight x-y corrections to put the images in perfect register (which isn't hard to do). A home video camera would not fit the bill, even if you could keep it steady, because its pickup of the shutter frequency would render the elements unuseable. But if anyone wanted to locate (i.e. prove/disprove the existence of) a visual code, this method would reveal it by underscoring the dissimilarities between two prints. Wait! I can hear the questions already: "But what about bootleg movies shot with handheld cameras? Huhhhhh?!" Given that there's a code to begin with, I'm not implying that this is how the CAP people decipher the data. They already know where to look, we don't. This would show us. ------------------ Better Projection Pays!

All information and technology for CAP Code was transferred to the MPAA in 1982. You need to contact them for any specific information or a "demonstration": Motion Picture Association, 15503 Ventura Boulevard, Encino, California, 91436.------------------ John P.

Here is my input on the CAP code, based upon all those years of chemical engineering and physics classes I took for no good reason:1. The assertion was made that maybe the sound is altered to reveal the cap code. It is possible to do so as there are frequencies that are not distinguishable to the human ear, HOWEVER, microphones cannot pick these up at all! So thats a bust. 2. It is however possible to encode the image of every frame on every print. How you ask? There are frequencies of light that you cannot see, infrared being one of them, but not the only one. You can encode just about anything you want to on to a frame of film with different light frequencies that are not able to show up on the film image, but are there none the less. When you scan the image into a computer (you must use a medical or scientific type scanner, not available on the general market of course) you can view certain frequencies and see whatever it was that you put on there. The PROBLEM with this is, that even with the greatest of video cameras on the market today, and those that have been with us for years now, have very little ability to pick these frequencies up. It is possible to make this work however. Cheap copies made with poor quality camcorders will not be able to pick up these freqencies, however the good copies, made with high tech transfers just may be able to transfer the image not seen as well. This is one way that CAP could be applied, and make it real, and possibly even traceable. Then again, It could be just a really good hoax!

What a disappointment! I've been watching this thread grow and grow without ever checking it out. It burst into flames and I still didn't check it out. Finally, tonight my curiosity got the better of me. I just wasted an hour of my life reading 84 posts and learning nothing! This is like an epic film gone bad. No... a Jerry Springer episode gone bad. No... Dateline! No... Maybe I'm not an inquiring mind, but I could care less if the MPAA could play a pirated video in reverse & have it say, "Bow to Satan". As long as I get a print that's heads-out, I'm happy. Piracy's gonna happen. Period. And I say, more power to 'em. If they want to go through all that trouble and risk the rath of "Mr. Vee", so be it. I see my movies for free, so what would I want some crappy vhs copy for? This CAP code thing, be it real or not, is just something to keep honest people honest... kinda like those locks on the poster-cases!
