IMAX Develops Movie Transfer Technology

kazama writes: "Toronto-based IMAX said that it had developed a new process called DMR (for "digital remastering") to digitally convert conventional 35mm films to the IMAX format without significant loss of detail. 'Our customers have been saying to us for years, "We want to see Star Wars on IMAX, we want to see The Matrix on IMAX." and DMR is the technology which is the enabler,' Co-CEO Bradley Wechsler told Reuters. 'That's going to be an increasingly important part of the company's performance.'" So what movies would you want to see on IMAX?

    This is confusing to me...a long time ago, I watched Jurrasic Park on an IMAX screen, and was disappointed - the image was not IMAX size (didn't fill the whole screen)nor aspect ratio. The only benefit was the better sound system.

    But recently, I went to the local mega theater to see SpiderMan, and was suprised to learn they were showing it on the IMAX screen. I expected the same thing, but it wasn't - it was a full sized IMAX image, and the image quality seemed fine to me.

    So if this technology in the article is some new innovation, how are they doing it right now, and what are the disadvantages of the current approach?

      (* That was my sense on it. I think that the digital transfer must be to improve the resolution somehow....? *)

      You can use digital techniques on some analog images to sharpen the image a bit. However, it would also likely sharpen the film grains, which you don't want.

      Thus, they probably have another technique which cleans up the film grain by comparing it to subsequent and/or prior frames.

      For example, if there is a dot at point X in frame 120, but that same dot is *not* in point X in frame 119 and frame 121, then it is taken out or reduced in magnitude. In most movie images the scene does not change significantly from frame to frame. Thus, you can take advantage of this duplication to figure out what is likely film noise.

      (If the background around the example dot in 119 and 121 is different, then perhaps you leave it alone because it may signify movement there. Graininess is harder for the eye to notice around movement anyhow.)

    If a feature length film was shown on an IMAX screen, the studios and IMAX were probably looking the other way.

    IMAX and the Hollywood studios don't want some hack to display regular film onto an IMAX sized screen. Its going to look bad, period. Even if you go to a multiplex that has a "very large screen" (General Cinema's Green Monster Screen in Boston, MA comes to mind) movies look like crap on it. Jittery and grainy.

    However, IMAX and the Hollywood studios are waking up to the fact of revenue potential from full feature length films being shown on IMAX sized screens. Of course this must be done according to IMAX's brand level of quality. IMAX DMR represents the initiative to do get this done. The first feature length hollywood film to be shown with this technology will be Apollo 13. So if you think you have seen a movie with this technology and it wasn't Apollo 13 pre-screen and you were a member of the public when you saw it, then you are deluding yourself.

    Disney's Beauty and the Beast represented an earlier "beta" generation of this technology. So if you saw that you get some idea.

    Would it make economic sense to convert The Matrix? How many people would pay $10 to see it again on a really big screen? Maybe first run movies would be a better bet.

    I, for one, would love to see The Matrix on an IMAX screen. I think it would be a great experience.

    That's why you go to a theater you know. For the experience. Otherwise, DVD and VHS would've killed them a long time ago. Why bother paying high ticket prices and overcharged on underbuttered popcorn and $7 drinks? Because there's something magical about being in a huge auditorium, in a room filled with strangers, going on imaginary adventures with people who never existed.

    I would kill to see a marathon of Star Wars (Ep. 1,2,4,5, & 6) on IMAX (and of course do it again once Ep. 3 is finished). It would be a wonderful experience. The sights, the sounds, I think there would be absolutely nothing like it.

    But there's a lot to think about here.

    Firstly you have the screen itself. Last year, when Beauty and the Beast made more bundles of cash by making a "Special IMAX Edition" there had to be a change. And I'm not talking resolution, I'm talking frame-wise.

    IMAX screens are 1.33:1 (television) aspect ratios. Most films are 1.85:1, and most of the classics are 2.35:1

    So when they blow up films to fit this huge screen, not only are they losing resolution, they're losing part of the image all over again. It's called Pan & Scan, or Hack 'N Slash, depending on your viewpoint.

    I could go on the huge tirade about how P&S is awful, how its destroying cinema as we know it, how it scares away Joe Blow from the infamous "black bars" and "why can't I see the rest of the picture" bullshit that myself and others have dealt with for years (ie, those in defense of widescreen).

    The point is that The Matrix was not filmed in "Open Matte." Open Matte is where the black bars are put there intentionally, so the film can be shown in theaters properly. So when the home video comes around, you don't even have to worry about loss of picture, because the 1.33:1 frame actually shows more than what you originally saw in the theater (the great Run Lola Run was done this way). In those cases IMAX reproduction would rely solely on the resolution, with nothing else to worry about.

    However, most of the films that are "classics" are in 2.35:1 "Superscope" meaning that when you pan and scan, you lose up to 33% of the film. For example, you have Star Wars, Raiders of the Lost Arc (all of the Indiana Jones films for that matter), Lawrence of Arabia, Pulp Fiction, etc etc. The list can go on.

    So when you think about IMAX reproduction of films, the frame is more important than the resolution. If you pan and scan a classic, you don't get the classic, you get what an editor "chose" to see at a particular point. And this to me is paramount.

They were struck in 1999, for some reason, and shown at the El Capitan (a one-screen Hollywood movie palace owned by Disney). They looked gorgeous, although they did reveal the limits of the source material. (Fun factoids: the scenes with live actors inside the computer were filmed in 70mm black and white, then blown up to cel size for rotoscoping/effects work, and re-shot on an animation stand. The computer animation was rendered on an IBM System 360 mainframe with custom software by Abel Systems.)

    OT:
    Before the screening there was a little round-table discussion and Q/A session with Steven Lisburger (writer/director), Bruce Boxleitner (who played Alan/Tron), Cindy Morgan (who played Lora/Yori), and one of the Abel systems people who made all those computer animated sequences possible - I think it was Tim McGovern. The director mentioned that he always thought of TRON as "the Bill Gates story" - i.e. the plucky young programmer breaking the shackles of centralized control (IBM). He said a lot of other stuff I didn't care about - I always hated the actual plot and acting of the film - but at least the Abel Systems guy got to talk a bit about doing CGI in 1982.

Poor Ansel Adams- if he had been alive now he could just use his $35 disposable camera and get those huge blowups with startling detail

The only advantage I see to this is the marketing ploy- Genuine IMAX Film SIZE!. You don't gain detail, you don't gain ANYTHING that isn't already on the film. And since you are starting off on a small format to begin with, its not going to get better.
    Now don't get me wrong, you can improve some work with digital sharpening and whatnot- going to a larger format helps there.

If you blow up the camera negative to 70mm and stay at 70mm throughout the print-making process, the result will look (marginally) better than a release print made from 35mm intermediates.

  27. Bring back 5-perf 70mm instead by Apotsy · · Score: 3, Informative
    Here is what I had to say when this subject came up on Metafilter:

    IMAX is the wrong aspect ratio for most movies.

    The proportions are almost like TV (about 1.4:1), whereas most movies made in the last 50 years are much wider than that (some are more than twice as wide). Nearly all movies seen in theatres in the last 20-30 years are one of two aspect ratios -- 1.85:1 or 2.35:1. Fitting those wider frames into an IMAX frame presents exactly the same problem that showing them on TV does. You have to fit a rectangle into a square, rougly speaking. That means either letterbox or pan-and-scan.

    However, Apollo 13 will probably transfer to IMAX fairly well, because it was shot in Super 35, which even though it usually is used to produce a 2.35:1 widescreen image, actually has a negative area that is much more squarish (again, about 1.4:1). So I would imagine that the IMAX transfer will make use of that extra image area. For more info on Super-35 see here, about 3/4ths the way down the page.

    Still, many of the movies people mentioned in this article were shot in widescreen processes other than Super-35, and would have to either be severely cropped, or letterboxed within the IMAX frame, in order to be shown from IMAX projectors.

    The right thing to do would be to bring back 5-perforation 70mm, which has a nice wide aspect ratio of 2.20:1. During the years from about 1976-1996, most major studio releases had at least some 5-perf 70mm prints struck. Chances are, if you went to the movies in a major US city during that time, you saw a number of films in 70mm six-track, perhaps without even knowing it. (The process was killed off by digital sound in the mid-to-late 1990s.) Everyone saying "I want to see Star Wars!" should realize that it has already been released in 70mm -- back in 1977.

    Of course, 5-perf 70mm existed long before the years I just listed, but it was mainly used for films that were actually shot in 65mm. The time period I'm referring to is merely when 35mm->70mm optical blow-ups were popular. This new IMAX process sounds like a bit of a throwback to those days, but at the expense of correct aspect ratios. And the blow-up is now done digitally rather than optically.

    Not only is IMAX the wrong aspect ratio for a lot of movies, it's also incompatible standard feature films in many other ways. 35mm feature films these days are shot with lots of tight close-ups and quick cuts, and if you look at the IMAX Filmmaker's Manual, they very clearly suggest that you not do things like that, because they are very jarring on the IMAX screen!

    Due to the above problems, I think people are likely to be disappointed with this in the long run. IMAX is probably pushing this idea because they are hoping this will boost their stock price.
