Is it possible to record a stereo movie with 2 cameras behind the polarized glasses they hand out? The screen us a flat movie screen, not the dome things... Or do the glasses work for eyes but not camera lenses? | ||

Unless the camera lens or CCD doesn't do some polarization filtering of it's own it should work. You'll have ghosting and the setup will be a pain and you will have problems synchronizing the streams later on AND it's illegal of course. Christoph | ||

Do the usual handhald cameras of today do any polarization? VHSc, Hi8 or DV? If there is no warnings or signs about "No cameras" or similar, is it really illegal? Personal backup?  How come the ghosting? There is almost none when viewing it myself? Is it because an eye and a camera lens isn't quite the same? | ||

I think it should work. Anyway you cannot find any warning like "Please, don't kill anybody in the theatre!" but you usually don't do it (I think) ... :-) I think ghosting may occure only because you'll not be able to keep the cameras exacly at the correct angle in respect to the screen ... but if you're going to try ... well, I aspect you'll get something quite good. | ||

The existing camera shuld not to do any polarization becouse it will give corputed unrealistic images of light plarizating surfaces - water surfaces, glass surfaces e.t.c ... There will be another problem - the camera will not be in sync with the movie. It means that parts of the frames on each camera will be black ... This could be correctd in post procesing by using saomthing like acumulation buffer for the image re-creation ... You shuld try the equipment with PC before going to IMAX ... | ||

BTW, who wants to see an IMAX3D movie at home? They're so dull, meaningless and stupid. In the theatre you have at least the giant field of view, insanely high resolution and incredible sound, but on video? Christoph | ||

Actually, the Luxor hotel in Las Vegas, Nevada is showing an amazing IMAX 3-d film consisting of a bunch of animated shorts..including the Compter-Generated Homer Simpson-Twilight Zone spoof from one of the Halloween episodes. Maybe once the killer 3d-effect wears off, they are dull, but I left the theater wanting more... -Jeff | ||

I saw the Cyberworld 3D movie which jorwik refers to in IMAX3D at the Panasonic IMAX at Darling Harbour, Sydney and was suitably impressed that I dragged some 3D Studio Max friends along to see it a second time. We considered borrowing various handycams from various friends and discussed the logistics of filming it, but in Sydney at least it appears impossible. I don't know the same IMAX3D system is used elsewhere. The glasses are not in fact polarising glasses, but 24Hz LCD shutterglasses. that is 24Hz for each eye, the projector is projecting a 48Hz image with alternating left and right frames. The glasses are battery powered and not always charged up. don't know if its lazy staff or dodgy batteries but on my second visit i got some pretty impressive ghosting from not-quite-black lcd's i presume. The image was perfect on my first visit. The glasses use 3 infrared sensors to synchronise with the projectors. the sync pulses are provided from infrared emitters all over the theater. We had the choice of PAL (50 fields 25 full frames) or NTSC (29.97 full frames) handycams, neither of which would suitably capture movie standard 24hz projected images, also fitting the damn things into the glasses could be a problem. not to mention recombining the streams later = ) plus capturing a 3 to 4 proportioned 10 storey screen from maybe 50 meters away at the most could be interesting without multiple wide-angle lenses which would make it even easier to fit two handycams into the glasses = ) I guess it you were really devoted and had two laptops with video capture devices and scsi raid, (or one laptop with TWO video capture devices and probably two seperate raid setups, and if anyone finds one of these let me know = )]. you could attempt to take the synch from the laptops IR ports (or if you don't feel like holding up the laptops use DIY UIR style devices), or you could put the ccd's behind the glasses and combine the streams manually timed later. grab two colour ccd cameras and away you go. = ) or you could wait a few weeks / months whatever, save many $1000's of dollars and buy the friggin film on tape or dvd or whatever... i seen lots of IMAX3D vhs and dvd on ebay but i never bought any.... i have no idea how you would play them back... | ||

All the official IMAX-3D VHS and DVD's are plain flat copies. Some 3D-DVD-copies for shutterglasses are announced. See the NEWS section and this thread: http://www.stereo3d.com/discus/messages/21/669.html?995484029 Christoph |
