Author Topic: Superman Returns Mike Schindler Phenomenal Film Handler Posts: 1039 From: Oak Park, IL, USA Registered: Jun 2002 posted 06-14-2006 09:53 AM                     Am I right in thinking that there will be no 2D Imax presentations?  |  IP: Logged Tim Rectanus Film Handler Posts: 51 From: Raleigh, NC, USA Registered: Jul 2005 posted 06-14-2006 11:06 AM                        No, As I understand it there will be 2D IMAX presentations of Superman Returns but only in places that do not have 3D capability. The only reason I say that is I heard that 2D theatres are getting their prints after the 3D theatres, which is hard to believe with the short Build time we will have. But It makes sense, 3D theatres have twice the work so they get the first shipments.  |  IP: Logged Mark J.

Also, are theaters using their existing polarizer filters modified with the swivel attachment, or are they receiving new polarized filters? My real question is, what is the configuration of the 3D glasses? ^, |_, circular, ...?  |  IP: Logged Tommie Evans Expert Film Handler Posts: 116 From: Birmingham, West Midlands, UK Registered: Sep 2004 posted 06-14-2006 03:08 PM                     I am guessing the 2D to 3D conversion would either be a pain staking frame be frame process similar to rotoscoping or color-timing or partly aided by computer image interpolation. If you examine a series of frames taken from a camera moving left to right it is easy to see that one or two previous frames will be close to the left eye view and the current frame will be the right eye. i.e.: left eye = Frame X-1 Right eye = Frame X (data is easily extracted for the conversion process) This is based on the camera moving at a constant speed in a horizontal direction (most 3D is taken from two images with a horizontal offset) and the subject matter does not change. It is simple to create a software program to analyze and combine two frames of film to achieve a 3D frame. However, each frame of film will have depth, perspective, focus, motion, subject movement and colour changes. Complicated pixel interpolation may come into play filling in the missing gaps between L/R eye. and/or expanding areas of the image especially in the foreground and background. This creates two images out of one, each tilted and distorted to generate the illusion of depth when combined. Also motion tracking algorithms may look a couple of frames in advance to ensure fluid 3-D motion. A similar effect was used on the Matrix Trilogy flo-mo sequences to add frames to the sequence i.e. from 125 still camera shots 5-6 interpolated frames were added between frames to smooth the effect and or speed up/slow down the movement of the camera/action. This process works for a single image, however using pixel by pixel interpolation and pixel/motion tracking enough data can be provided to create a believable 3D image?  |  IP: Logged Brian Michael Weidemann Expert cat molester Posts: 944 From: Costa Mesa, CA United States Registered: Feb 2004 posted 06-14-2006 04:37 PM                        quote: ^, |_, circular, ...? I don't believe any IMAX systems use a circular polarization. But, to use your notation, our location has ^ and will still use ^ after the upgrade. We're scheduled to receive our print on Saturday the 24th. We have a screening for Pepsi/Power106 on Monday the 26th at, like, 8:00pm. Polar Express 3D took me a total of 21 hours to assemble, which was 60 reels total. (Granted, that's when I still took the time to properly paint the splices, which had to dry before taping ... a practice I've abandoned--due to numerous late print delivery times--in honor of a quick Sharpie on the very points of the splice, just to eliminate all time that's not used actually loading film.) This one's 90-92, with three trailers. I'm excited! I'm supposed to do this without exceeding 12-hour shifts per day? I think I may get some double-time pay out of this, if this has to be done properly.  |  IP: Logged Mike Schindler Phenomenal Film Handler Posts: 1039 From: Oak Park, IL, USA Registered: Jun 2002 posted 06-14-2006 05:28 PM                     In terms of footage, how long is an Imax reel in comparison to a 35mm reel?  |  IP: Logged Brian Michael Weidemann Expert cat molester Posts: 944 From: Costa Mesa, CA United States Registered: Feb 2004 posted 06-14-2006 06:14 PM                        3-3.5 minutes versus (as I recall) 17-20 minutes. IMAX is also 24 frames per second.  |  IP: Logged Mike Schindler Phenomenal Film Handler Posts: 1039 From: Oak Park, IL, USA Registered: Jun 2002 posted 06-14-2006 06:45 PM                     Brian, what would that translate to in terms of actual physical length?  |  IP: Logged Brian Michael Weidemann Expert cat molester Posts: 944 From: Costa Mesa, CA United States Registered: Feb 2004 posted 06-14-2006 07:01 PM                        15 sprockets per frame as opposed to 4 sprockets per frame. The mathematics are left to you. I'm sure these technical details of the format have been covered many times in more appropriate threads.  |  IP: Logged Michael Coate Phenomenal Film Handler Posts: 1904 From: Los Angeles, California Registered: Feb 2001 posted 06-15-2006 12:12 AM                     I don't want to hear a peep out of Warner Bros. about how expensive these prints were to strike. And here's the list of venues scheduled to show "Superman Returns" in IMAX (& IMAX 3-D, well, sort of).  |  IP: Logged Dick Vaughan Phenomenal Film Handler Posts: 1032 From: Bradford, West Yorkshire, UK Registered: Jul 2000 posted 06-15-2006 01:26 AM                        quote: Mike Schindler Brian, what would that translate to in terms of actual physical length 1570 24FPS runs at 337.5 feet per minute so 3 minutes = 1012.5 feet That means a 2D 150 minute feature is 50625 feet therefore Superman Returns 3d weighs in at just over 100000 feet of Mr Eastman's finest 70mm stock. Should put a smile on John P's face  |  IP: Logged Brian Michael Weidemann Expert cat molester Posts: 944 From: Costa Mesa, CA United States Registered: Feb 2004 posted 06-15-2006 03:13 AM                        And just shy of half that is going to be the finest quality blacked-out slug that money can buy!  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 06-15-2006 07:30 AM                        Indeed, Kodak's manufacturing folks have been very busy making an additional 5 million feet of 70mm print film for this production. Who said "70mm is Dead"? It's just been reborn in another format.  |  IP: Logged Paul Linfesty Phenomenal Film Handler Posts: 1383 From: Bakersfield, CA, USA Registered: Nov 1999 posted 06-15-2006 07:55 AM                     quote: Michael Coate And here's the list of venues scheduled to show "Superman Returns" in IMAX The Regal stack ad in the Fresno Bee indicates that it will play at the Edwards Theatre there in IMAX 3-D, and their website is selling tickets for SUPERMAN RETURNS: an IMAX 3-D Experience.  |  IP: Logged Mark J. Marshall Film God Posts: 3188 From: New Castle, DE, USA Registered: Aug 2002 posted 06-15-2006 08:41 AM                    I'm kind of excited about this. But for all of this work and expense on the presentation side, to not shoot the thing in 3D and/or 65mm in the first place is profoundly lame.  |  IP: Logged
