The Future of Digital Cinema 244

Posted by michael from the sticky-floors dept.
An anonymous reader writes "The New York Times recently had an interesting article on the future of digital cinema. The article talks mainly about the Digital Cinema Initiatives consortium (formed last year by a group of seven major studios) and its work towards establishing a set of standards for theatrical digital projection. DigitalCinemaMag also had an article back in February about the consortium's efforts which included a few more technical details."

      The Attack of the Clones was produced with a digital camera and then tranferred to film. There is no reason why the 35mm version would look any better. If it looks worse on film it is probably because of the technology used for the tranfer.

      To make the comparison fair you would have to view it side by side with a fresh 35mm print of a film shot with standard equipment. My bet is that it would look inferior.

      I saw the digital version in Santa Clara and couldn't tell the difference between film. There may be some difference to a trained eye but to most of us it's like the difference between 2.8 GHZ and 3 GHZ Pentiums.

      Theft is a bigger issue which may be why the studios are trying to get to a level where you have to have the hardware to get an image that blows away whatever a pirate would use to show the movie. Several years ago, Silicon Light [siliconlight.com] developed a display technique that appeared quite promising. It was a high speed optical switch that appeared to be easily scaleable from the 1080 lines they originally demonstrated. Even at 1080 lines, the contrast ratio was 3000:1. Unfortunately, Silicon Light sold the display technology to Sony who has done zip with it in the intervening 3 years.

      Keep in mind that a higher framerate equates into larger files and more processing required which then equates into higher costs. You have to transfer a larger file, have more space to hold it, and have more processing oomph at the theatres to decode it. Hopefully whatever standard they come up with allows them to have variable framerates (as you would expect them to have variable resolutions and compression ratios, ala DVD). So Mr. Lucas can release his stuff at 60fps at 8192x2048 using lossless compression while some indie can do theirs at 24fps at 720x480.
      • Compression Rates are completely different that FRAME SIZE. DVD has a frame size of 720x480. Although The dvd spec allows for a couple others 1/2 D1, Mpeg 1 (Compression Type change), All major studio DVD are at the SAME FRAME SIZE 720x480. You may be referring to the variable bit rate encoding MPEG II.

        OK, you've piqued my curiosity. Just how much storage?

        Let's start with a two-hour film shot at 60fps with 2048 lines of vertical resolution, 48bpp color, and a 2.35:1 aspect ratio.

        If we round off the screen resolution to 4800x2048, that's 9.375Mpixels, 56.25MB/frame, 3.3GB/second, or about 23TB for a two-hour film, uncompressed. I don't know much about video compression, but it sounds intuitive to me that you could get 5:1 compression and still get an OK picture, which works out to about 4.6TB. Let's round that up to 5TB for a good back-of-the-envelope guess.

        By the time movies start coming out in a format like this (someone still has to build the cameras and the post-production infrastructure), a single hard drive should be able to hold that much, but that still sticks you with mailing physical media to the theaters. I'll leave it to someone else to do the math as to whether multicast distribution over a private network would be feasible.

        I think in the meantime, we should follow Roger Ebert's recommendation for improving the viewer experience. Switch to 35mm film at 48fps. The projector mods are much less expensive than digital projectors,and they're backwards-compatible with conventional film. In its current incarnation, digital is a boon to the studios at the expense of the theaters.

        (Side note: Showscan, 70mm film at 60fps IIRC, was the coolest thing I've ever seen projected anywhere.)

          Video compression is done largely by storing only what is different for each frame compared to the previous one. And obviously, the more frames per second you have, the more identical to each other they will look.

          So I suspect even a frame rate doubling will not have more than a 5-10% effect on file size. Just a laymans opinion, but still.

          And with the same disclaimer, I'm pretty sure you can get much better than 5:1 compression.
        • I think that the popular video codecs would be more efficient at compressing video with a higher frame rate, because they store mostly the difference between two consecutive frames, and not the frames themselves. In a higher-fps video stream, there ought to be less difference between consecutive frames -- that's the whole point, so it seems to make sense that doubling the frame rate would increase file size by a factor slightly less than 2.

      One possibility that's really only feasible with digital projection is the possibility of having a film change its framerate on-the-fly to accomodate what's going on on the screen. For example, a movie might run at only 24 fps for a slow dramatic scene. Then, when the action starts, it could ramp up to 60fps for extra-smooth explosions and ramp back down to 24 fps afterward.

      Once digital projection is a reality, all sorts of new possibilities in filmmaking open up...

    • I've talked to a few cinematographers and they all believe 24 fps is an important component of the "film look", along with grain and other artifacts of film technology. There are effects houses that say they can make digital video look like film.

    Here's a bit of info on Finding Nemo [boxoff.com], which on the other hand was a digital gem. No noticeable pixilation, and vivid colour.

    From others' comments about AOTC YMMV but I don't know why. Does anyone know why different people seeing this saw such a disparity in picture quality?
    • I had the same experience. I saw AOTC DLP and was not impressed. I saw it again later at 2nd-run theater and the non-digital projection actually seemed better.

      I went to see Nemo the first weekend it came out. I happened to get a DLP showing (didn't hunt for it like I did with AOTC) and it was really good (far better than star wars). I saw Nemo again the next weekend with another group, this time regular projection. I have to say the digital projection was sharper and had better color.

      • Now I want to go see it a 3rd time, back to DLP to see if it really was that much better, or if I'm imagining it.

        I believe you accidently stumbled across the real reason for the switch: People will see movies numerous times to see if the quality is better in the digital version or the film version. If everybody who currently sees movies sees everything twice, well... I'm no math whiz, but that seems like a lot of money to me.

      The biggest technical hurdle with high resolution digital movie cameras is moving all that data from the CCD to the disks. According to one friend who is working on such a camera, they are using several independant PCI busses feeding large arrays of disks.

      When you think about it, it's remarkable how much bandwidth analog film has - you can store the equivalent of 10s of megapixels in full color in 1/250th of a second and be ready to shoot the next frame as quickly as you can move the film, compared to the 4 or 5 seconds my 4 megapixel camera takes to store an image.

    I saw Episode II in DLP at Odeon, Leicester Square and at first glance it looked good - there was none of the dirt, scratches or jumping associated with a badly looked after and badly presented 35mm print. But I soon realised that it looked somehow dull - it had none of filmic qualities that bring a life to a print which come from 35mm. It was impressive for an emerging standard, but the quality wasn't quite as good as a well presented 35mm print and there's no way that even touches 70mm prints.

    Another point is the digital cinema takes away the skill that comes with projecting a film - go read the forums over at Film Tech [film-tech.com] and see the care and pride those guys take over the film presentations at the cinemas they work. Those guys know how to present a film properly.

    What matters is not image quality in a test laboratory, but image quality in the local gigaplex. I believe biggest factor determining image quality in current theatres using traditional film is not the technology, but whether or not management gives a damn about picture quality.

    For example, take dirty film. There is no reason why film should get scratched or dirty if it is being handled competently. In at least perfectly ordinary local theatre (Showcase Cinemas in Randolph--no, I have NO connection with them except as a satisfied customer) prints run for weeks and weeks and still look absolutely pristine. In other venues, I've literally never seen a showing where the film was clean and unscratched.

    So far, I have managed to go to two DLP screenings in the Boston area. In one case ("Ocean's Eleven" at the Randolph Showcase) it looked pretty much the same as 35 mm. Some ways better, some ways worse. Beautifully steady and flicker-free (better) but I had to sit a little further back to avoid seeing visible pixel structure (worse), and it seemed to me the blacks were greyish. Really, about a wash.

    The other time... ("Fantasia 2000" at the General Cinema in Burlington)... well, what can I say? The gear was out of commission and they were showing 35mm film in the house that had been designated as showing digital.

    Given that the equipment in both venues was probably almost brand-new and hardly used, 50% success in just having the equipment function is not a very good track record.

    When operated IN REAL LIFE under the same management as current theatres, using projectionists trained the same amount... how is digital cinema going to hold up? No, the picture will never look scratched, bits being bits, but the media can still get scratched... will there be dropouts? skips? Poorly maintained analog produces a poor picture, but poorly maintained digital can't give you a show at all.

    Currently, digital films are loaded off of multiple DVD's onto big, fast disk arrays. How will those fare? Are the disks hot-swappable and will all the theatres have a good supply of spares to swap in if they fail?

    Not only does digital projection equipment cost five or ten times what conventional projectors cost, but conventional projectors have service lives that are extremely long--many, many decades. Somehow I doubt this will be true of digital projectors.

    Do you really think theatres are going to be anxious to put in projection equipment that is an order of magnitude more expensive, just in order to get a picture that is ROUGHLY the same quality as they get from 35mm? And far, far lower than the quality available from 70mm, common just a few years ago but almost extinct now (the current generation may never have a chance to really _see_ "Lawrence of Arabia" or "2001, A Space Odyssey").

    The move to digital cinema is obviously beneficial to studios and distributors, but I'm darned if I see what it does for theatres or theatregoers.

    • Your comments are dead-on correct. I worked at a cinema near you for many years (Showcase Woburn). When I started, there were full-time projectionists whose only duty was to keep the movies running smoothly.

    A 16 megapixel camera has two discrete greens for ever red and blue CCD cell yielding a sad-ass 16/4=4 megapixel image (or 2000*2000 in theory) though there are no 16 megapixel cameras really, and the best tri-layer camera for 5,000 bucks is almost 2000 across but takes 9.4 SECONDS to save a single image.

    The solution : a 100,000 dollar Thomson Viper.

    The Thomson Viper can take a 1920*1080 pixel 10 bit (log color compressed) frame every 6oth of a second and stream it out on TWO DIGITAL cables.

      As a professional photographer and visual effects guy, I have to disagree with you. This is a religious war that comes up frequently, so I'll be practical and hopefully brief.

      When comparing pixels to film, the actual pixel resolution is only part of the equation. Yes, standard color CCD arrays use an offset-overlay technique to interpolate more resolution in the final image than any of the single color channels has. The exception to this is the Foevon [foveon.com] chip, which has full color in every pixel, and the very high end systems you mention above.

      The huge, HUGE advantage of digital imaging that you have not mentioned is grain. The spatial resolution (or how much detail is actually in the picture content) is actually very poor in 35mm, especially in less-exposed areas. If I accidentally underexpose my digital image by one or two stops, I can use a level adjustment to recover a near-perfect image with very little grain, and plenty of detail in even the darkest areas. If I try that with a 35mm film scan, it will be extremely grainy, even from a very low ISO film. The reason 35mm gets by is that at full frame from a reasonable viewing distance and at a correct exposure, the softness, gamma, grain and falloff present a nice pleasing picture.

      In every day practical use, I find that a 6 megapixel standard CCD (not foevon) producing a 3k file has better detail than the average 35mm image. Downsampled to 2k and it's an extremely sharp, excellent 2k image. Right now I even have a 3 megapixel (2k) image from an older camera on a billboard just outside of town, it's about 15 feet across, looks really nice! Average viewing distance is a big factor as well.

      Most digital visual effects for 35mm and features finished to anamorphic 35 are rendered at 2k resolution. A few years ago I did most of the animation on a 35mm film spot for American Express. It was rendered at 2k and transferred to 35 and it looked gorgeous. If you have very sharp spatial resolution in your 2k image (such as computer generated imagery where every pixel is sharp and perfect) you will not gain much of an advantage going to 3k or above. The only thing that kind of resolution is useful for right now is IMAX. I dispute the idea that 35mm has 4k of useful pixels. After about 3k you won't percieve any practical difference.

      CCD technology will not be able to replace film (35mm) for at least another 5 years, if ever.

      5 years for widespread distribution is practical. "ever" is ridiculous. :)

      Remember, when talking technology, think about practical application and end results. pixels don't exist in a vacuum. (but when they're on a CRT they exist in a vacuum tube! :)

      Personally, I'd like to see variable frame-rate 2k to 3k systems for regular movies, and 4k - 5k digital systems for IMAX sized projections, using a format that can be created and previewed on desktop PCs with very fast disk arrays and hires monitors. (check out IRIDAS [iridas.com] for an excellent digital cinema and desktop hires playback system, including 3D!)

Google pulls up a mail list post [canopener.ca] with links to the original articles, here [guardian.co.uk] and here [guardian.co.uk], both very much worth reading again. The NYT article is all shine on.

    The summary is that the new technology will enable Hollywood to crush all competition, small and large. Through closed "standards" they will control who can use the projection equipment and what it plays and when. Because no local copy exists, it will all be under the control of the current big movie makers. By using a an industry body like the DVD consortium, they can make sure that no one but them has access to the secret format the projectors use and keep projection equipment so high, no one can afford to have anything but them. So, it will be there way or the highway. No mix and match and no competition except from complete independetnts who will be hobbled by a lack of equivalent quality equipment.

    It's the same old story since media was invented, patent, legislate, collude and screw everyone you can.

    1. I was one of those "grain sniffers". I was at a demo of an upcoming 11,000 lumen high res projector standing a few feet away from the screen, and I couldn't see any pixellation. The brightness and sharpness was astounding. Plus this project runs Linux, decrypting the image on the fly.

    2. Image quality depends a lot on the projectionists. I sat in the projection booth of a megaplex for a week a while ago and saw three different projectionists opening up in the morning, and while all of them cleaned the lens, film gates and transport mechanism on the projector, not one of them cleaned the glass at the front of the booth. You could see dirt and finger marks on the glass even before they struck the lamphouse. I asked one of the projectionists about it, and he was pretty contemptuous of the type of audience they got at that plex and the type of low brow action-heavy movies they showed there. I got the impression he wanted to be at some arts house, and maybe if he'd had more respect for the audience he would have worried more about their experience. On the other hand, I work with another projectionist who is meticulous about every aspect of the showing.

    I watched the show at a distance of about two screen heights, and I could make out pixels and annoying aliasing problems throughout.

    The colors were good, the picture was steady, no compression artifacts to speak of, but the resolution was clearly inferior to the 35mm projection I had seen the day before on a comparable screen. The end credits in particular were hard to read and had visible scaling artifacts.

    This is clearly unsatisfactory. Will the 'standard' for digital theater projection have significantly higher resolution than what we saw last year? Will the early adopters get burned?

    According to the Star Wars website, ep II was shot on a Sony digital movie camera with a resolution of 2.2 megapixels, which is just slightly more than regular HD. I don't even think the theater projection used had full HD resolution. The projection system seemed to have an odd pixel resolution which didn't match that of the movie, which may account for the apparent blur and pixel artifacts.

    I'm generally not a fan of the idea of all-digital theaters. Too much control from Hollywood and potential for dirty tricks - in the future, when you see a movie in the theater one day may, your friend who sees it the next day may have a wholly different experience as the picture could be continously 'tweaked' and digitally re-edited to 'reflect' the whims of mass audience and address their concerns. Ick. Revisionism abounds.

    If Star Wars ep 4 was released today, Lucas might have launched the picture with Han shooting first, the next day wimping out and deciding Greedo should be shown shooting first. Ya know?
