    I first noticed it when I got an insta-migraine 30 minutes into a bootleg of the perfect storm - there's a barely perceptible flicker from the 24fps of film going to 30fps of video; it's not enough to be noticeable, but it causes me all sorts of problems and aftereffects (like if i walk around in the moonlight afterwards, the brightness level "pulsates" for a good 15 minutes). i imagine this will be a lot more severe, but still, the existing problems have already turned me off to videotaped bootlegs.

I pick them up to see if the movie has actual plot (you know, the thing that matters everywhere except in porn). Since most of the garbage coming out of Hollywood lately doesn't pass even this lowest of the lowest criteria, I get to save some money that would otherwise be spent on completely unsatisfactory experience (money back guarantee anyone? in movies???). The good movies still get my buck (theatre & DVD), but the bad ones get zilch.

      Considering the ratio between former and latter, yes I belive this cams are hurting their bottom line. What I also know is that they can try everything short of taping peoples eyes, the end result will probably still be the same, just the reviews will be harder to come by (in sense that I will then have to find a critic whose taste is very similiar to mine) compared to be my own critic.

    To combat camcorder piracy Cinea and Sarnoff will develop methods of encoding films with artifacts that are invisible to the human eye, but play havoc with the electronics of a camcorder.

    I suppose that given the natural latency of the human eye, this could work. When I pick up a TV screen in my old-style video camera, the picture has bands of light and dark in to, presumably due to the scan rate of the camera matching the scan rate of the television.

    In the movies, when you see a scene with a television in it, why are there no such artifacts? Is it due to shooting with film, camera speed, ?? I would think that adding some sort of latency in a video camera to emulate that of the human eye would render such protection schemes useless.

      I would think that adding some sort of latency in a video camera to emulate that of the human eye would render such protection schemes useless.

      That would be true only if the protection scheme relied solely on varying the projection flicker. My impression from the blurb was that Sarnhoff was going to target strengths of video cameras (greater light range sensitivity) and turn that into a liability. For example, many CCDs can see infrared wavelengths (train a consumer video camera at a IR remote and you can see the diode flashing.) If you wanted to screw with the recording, just overlay the projection with a high-wattage IR pulse, preferably in a shifting moire pattern to really mess up the viewer.

      However, if you're dedicated enough, all of these protection schemes can be nullified - with a progressive frame camera, shifting refresh rates can be ignored, with the appropriate filters extraneous IR/UV interference can be screened out. And, of course, none of these protection schemes can defend against a projectioninst collaborating with a pirate to telecine a print directly to video, bypassing the need to skulk in dark corners with a handycam...

      I work at a Video/Film Post House. There are two ways to achive this effect.

      Monitor Playback on Set.

      Footage must be converted to correct frame rate of shooting medium AND the playback machine on set must be synchronized with the camera. Standard video framerate is 29.97. Film is 24. Some "24" video is actually 23.976 fps. This conversion is done much like PAL (25fps) to NTSC (29.97fps) and causes motion artifacts on objects that move quickly. Software now allows for pixel tracking instead of frame blending for framerate conversion. Pixel tracking can create all-new in-between frames that are artifact free.

      Digital Creation (Monitor Burn-in)
      When the video is not available at time of shooting its inserted later on. Many times the interaction between the TV screen and actor would be too dififcult to coordinate on set. In this case, a green screen is inserted where the picture would be. Usually four dots are placed in the corners of the green to allow the computer to track the picture and adjust perspective of the "TV" footage. The inserted footage must be color corrected, slightly blurred,
      scan moire and reflections added and finally, add grain if the scene is shot on film.

    As for the cameras, I didn't know the restriction at my first screening, and I had my digicam with me. I put it in my jacket pocket and held my jacket in my hand when I held my arms out for wanding. They didn't notice a thing. I didn't use it at all, but it was pretty silly how easy it would be to get a camera in.
