Scott is correct. AFAIK, as it is now configured, a video taken of an image projected using a DLP Cinema projector will not have the flicker seen when using a camcorder to photograph a normal 24fps film presentation from a theatre screen. Piracy is a major concern with digital cinema, and the SMPTE DC28 Digital Cinema Committee has a large team of experts developing encryption and "watermarking" technology.The links to the MPAA, FBI and INTERPOL were in JEST!!! The specific questions being raised by Brad and others may be of help to pirates, and "inquiring minds" do NOT need to know the answers to them. Any portion of a film having CAP Code is tracable. It is not restricted to the titles or credits. The CAP Code is placed on...oops, there's that smell again...aseinfgetr slkde[a ha;sfdnrip rega/;nfk;wtw aahalja ljrhtinf okfj;ihpn fha[ramtz Excuse me, Mr. Pytlak seems to have had a slight fainting spell again. Good bye. Mr. Vee.

Paul:I'm NOT an expert on the DLP Cinema technology. But AFAIK, although the image on the TI DLP projector is refreshed 24 times per second, there is no blanking interval as might be found on a CRT display. With 24fps film projection using a 2-blade or 3-blade shutter, the flicker comes from the 48Hz or 72Hz frequency of the projector shutter not matching the frame/field rate of the camcorder. ------------------ John P.

Ok John, you've not answered the questions, but you did not dodge them this time. Instead you gave us the basic "I cannot answer these for it might help bootleggers", which is absolutely fine. Hey, it IS an answer, and it is obviously honest. I'll make one last point...just 'cause. So for the sake of this argument, we're going to say that the almighty CAP code has been placed on every single second of every single reel of the next big movie this year. Now, let's say that these codes are completely traceable, even on a 10th generation VHS dupe! Let's also go a bit further to say that the MPAA is going to catch this crook or die in the process. So, how do they expect to catch anyone when the depots randomly slap prints into unlabeled cans, stack them a mile high and THEN wander around slapping the stickers on them containing the destination theater and print number? Huh? How about that one? I think the MPAA might be taking those numbers on the print boxes a little bit for granted, as I know of three depots for sure that do NOT pay any attention to them, and I'm sure there are more.  Now, here is my question that I would actually like for John to answer. Who can I get into contact with to get a demo? Again, if this is so almighty and powerful, such a test would certainly strike fear into would be bootleggers and would be projectionists who would allow such an illegal action to take place at their theater. I stress again, no one has to say "how" on any aspect, just provide the print numbers and theaters the print came from. Note: these will be first run original prints and not hand me down prints for the test. I'm sure I can easily get 10 anonymous Film-Techers to assist with the demo. It will be done fairly.

Brad:If a feature has CAP Code, precise print tracking is part of the package, and is mandated for labs, shippers, and exchanges. Special handling and tracking is involved. You can try contacting the MPAA to arrange a "test". But they will be very suspicious of why "inquiring minds want to know". Decoding the videos does cost money too, so it is not something done on a whim or for curiosity. Again, I know CAP Code has been successfully used to investigate and prosecute film piracy for 18 years. Distributors wouldn't pay for it unless it worked. IMHO, that's the best "proof" that CAP Code is effective. ------------------ John P.

I get that all the time from Technicolor. "No problem, just swap the cans."Why do I get the feeling Mr. Vee is really Mr. Jack "V"alenti? I'll bet he's got John tied to a chair right now. This whole thread is turning into some kind of internet dodge ball with Mr. Pytlak as the captain. No one who claims to have any actual knowledge is providing any proof or is even willing to help set up a demo in any form. Sure anyone can come here and post "I know it works", but big deal! I could come here and post that same statement and as far as anyone is concerned, people would think I actually know what I am talking about. The CAP code is a bullshit threat. I wonder how many people really believe in this Santa Claus story? (No offense to Mr. Pytlak. Outside of this thread he provides invaluable assistance to everyone here and it is much appreciated.)

Carl:Providing any specific information to "inquiring minds" risks compromising the effectiveness. It's as simple as that. As far as running a "demonstration" with the MPAA, it would be like Saddam Hussein asking Israel if he could launch a few scud missles with "dummy" warheads at them to test their defenses and better understand how to defeat them. Another analogy would be protecting your own home against burglary. Who in their right mind would tell potential burglars their address and when they will be away on vacation, along with details about their home security system? Or let a potential burglar test their security system a few times to see if they can find a way to defeat it? ------------------ John P.
