Why Do Theaters Project Film Reels Instead of Digitally?


I don’t really like going to the movie theater. They’re not usually playing anything I want to pay $11 for, and $4 for twenty-five cents worth of soda is an unbelievable rip-off. Many people say to me, “But you can’t get the same experience at home!” They’re right. I don’t get an amazing sound system, uncomfortable seating, 40 sick people coughing in the Winter, and idiots clapping at the credits in my living room.

But what I hate most about going to see movies in a public theater is film. It’s a horrible archaic form of media that we still hold on to for some reason. In an era where we could easily project a massive high-quality digital image onto a screen, our projectionists still have to lug around enormous film reels, feed them into the projector, and switch them over at exactly the right moment. By comparison, they could be placing one big disc into a drive and hitting “play.”

Laser discs have been around since 1978! Blu-ray discs can hold up to 128 GB of data and they’re only 4.5 inches in diameter! Why haven’t we made the switch yet?

Well, in actuality, lots of theaters have begun to convert their theaters to digital projectors, but the units often cost $100,000 each. The theater I go to on the rare occasion that my wife convinces me to has 18 screens—considered average in metro Atlanta. That would mean a $1.8 million investment to update each screen just for an average-sized theater! Multiply that by the number of AMC theaters in Atlanta, and you’ve got a fairly massive chunk of money the company would need to burn.

They don’t stand to recover their money, either. The savings from distribution of optical discs is attributed to the movie studio who would previously have to dump a significant portion of a film’s budget—on average $5 million or more—to have a bunch of reels printed up. Pouring and stamping out discs saves them a lot of money, but it doesn’t save the theaters any money at all, so there’s hardly any incentive to do so. They wouldn’t need to hire less projectionists, because usually there’s only one or two people running all the rooms anyway.

Theaters are slowly updating, though, under pressure from studios who are getting sick of printing film reels and sending them out, but they’re finding it hard to convince people to head into the theaters to see movies in “all-digital” format. After all, even the highest resolution digital image has a hard time competing with the “infinite resolution” of film.

Here’s some reasons why we should all embrace digital projection at our local movie theaters, even if it doesn’t result in a reduced ticket price.

The picture quality is ultimately better. Sure, film enthusiasts will claim that nothing beats the intense colors and clarity of film, but you’ve got to go on opening night to see it. Why? Because every time that film is run through the projector, it runs the risk of getting damaged. By the time a reel gets shipped off to the dollar theater, it’s a horrific mess of scratches, dust, and artifacts. The fact is, the longer you wait to see a movie projected from film, the worse the picture quality will be. However, a digital disc never loses its picture quality, no matter how many times it’s viewed.

The entire movie can run off of one disc. In order to accommodate thirty frames per second for a minimum of 5,400 seconds, a film reel needs to hold a lot of still images, but each image needs to be big enough that it looks flawless on a forty foot wide screen. If every frame was put on a single reel, the thing would need to be impractically large, so most movies use four or five reels which a projectionist has to switch between at the exact right moment. Ever seen the black dot that shows up in the upper right corner of a movie sometimes? The first dot is a warning; the second dot is the cue to flip the switch. Watch, and you’ll notice that the picture and sound quality are briefly interrupted when the switch is made. I find it distracting, but then I’m a nerd that pays attention to that stuff. The projectionist is doing a delicate dance of running around the room flipping the reels at the correct moment as if maintaining a bunch of plates spinning on poles. There’s such a huge amount of human error that’s possible here that it makes a lot more sense to feed a giant, half-terabyte disc into a digital projector and hit “play.”

A wider variety of movies can come to each theater. Theaters don’t usually take a chance on an artsy low-budget film because they’ve got to make money off of it somehow. If no one knows what it is because the studio didn’t have a huge ad campaign to raise public awareness, it’s less likely that someone will go see it. Therefore, if a theater gets their hands on a copy of something like Rachel Getting Married, they’ve got to put it in the smallest theater and try to run it exactly enough times to maximize profitability. They don’t usually share films even within their own chain because it’s too difficult, dangerous, and expensive to send the stack of reels around the city. But if they each had their own optical disc of the low-budget flick—at a production cost of only a few dollars each—the studio could make back their cost with just a few ticket sales. (This would also benefit low-budget films who would no longer need to set aside a significant chunk of money to produce the reels.)

If this all sounds good to you, then there’s good news! In 2007, Variety magazine predicted that half of theater screens would be using digital projection by 2013, and adoption statistics seem to be supporting these numbers. And with the number of movies being shot on digital cameras these days, these display methods make more sense than ever. I’ll be looking forward to the day when I can go see a movie three weeks into its release when it’s just me, my wife, and a few other people quietly enjoying a scratch-and-dust-free film. Too bad ticket prices will be $15 by then.

  2. It's true. This is actually a really terrible article that I wrote off the top of my head without doing any research, which is a really bad idea.

  3. No kidding. It's contradictory as well. First, film is lower quality, but then it's higher quality...but then it's lower quality because it looks bad after it has been run for a while. Even now the movies you see in digital projection houses are not on disc. And having everything digital isn't going to help independent film because the movie studios still book their product according to contracts which still charge theater owners to exhibit the film regardless of how many shows or tickets they sell yet these contracts are very specific and won't let you insert any other film you want to show just because nobody is going to the 10:00pm kids movie.

    The one or two good points here are overshadowed by the idiocy of the other misinformation. FILM is higher quality. FILM is better. You are now paying the same price (actually, you're paying more now...how do you think the movie theaters paid for these new projectors? They charge you more, that's how) for a LOWER QUALITY product. IMAX is the only true high quality format, and I don't mean these new digital IMAXes. Those suck. Better than regular because it's IMAX, but if you've ever seen a film IMAX and a digital IMAX, you can tell the difference. Well, maybe not you, but people that care about this stuff can. Film IMAX is the true future of movies, and it's a shame the movie studios and theater owners have colluded to give the viewer LESS while charging them MORE and reaping the profits of their sheer laziness and greed.

    I ran a projection booth for years. You are WAY off. It seems like the only reason you got some stuff right is just blind luck. Thankfully, it seems like nobody really paid any attention to what you had to say.

  4. Film may be a higher quality format because of its high scalability, but even analog images have a limit before they become blurry and grainy. The digital equivalence of this is pixelation. So if a theater can project an image below the level that pixels are visible, the quality is going to be identical to that of film except to the rare few that can tell the difference.

    In fact, the major difference between film and digital projection in theaters is the actual medium displaying the movie. Very few films are shot, edited, and distributed entirely on film; the vast majority are shot on film and then converted to a digital format for editing and post-production. This means that a movie projected from a film reel is still displaying an image that is fundamentally digital. The only reason you don't see pixels is because the resolution in the editing stage is so large that it reaches beyond the restrictions of accurate focus placed upon the images by the film it is distributed on.

    Shooting a movie onto film may still be a superior method, since it generally results in a better range of light and more accurate color. But once principal photography is over and those images are on a computer, there's not much point to printing it out on massive film reels. Unless you like seeing scratches, dust, and potentially awkward projector switches.

    If production companies and theaters can ultimately save money by distributing and displaying the finished product digitally, why not? It seems like the only people who will notice or care are projectionists. It's the old "analog vs. digital" argument I've been a part of in the audio recording field for more than a decade. There might be more warmth in an analog recording, but since I'm going to be non-linearly editing on a computer, it doesn't make sense for me to master a recording and distribute it on cassette tapes. Everyone's still going to want a CD, high-quality MP3, or lossless digital format.

    I still support shooting movies on film. But I don't support the expensive and archaic tradition of distributing and displaying movies on film.

  5. "So if a theater can project an image below the level that pixels are visible, the quality is going to be identical to that of film except to the rare few that can tell the difference."

    In theory, maybe, but in practice it's far from it. You have to sit farther back to get a good image from a digital presentation. The great thing about film IMAX is you can sit closer and be engulfed by the image and it's still crystal clear. The quality of digital can never be identical to that of film, but it's true that the majority of people can't tell the difference or don't care. But then again, most of them never noticed and didn't care about scratches either.

    "This means that a movie projected from a film reel is still displaying an image that is fundamentally digital."

    Incorrect. The image is still fundamentally film because that's what it was shot on. Using a digital intermediate for editing basically makes all that CGI and color correction possible, so it's an unfortunate requirement these days. However, when they're done editing on digital, they still do a side by side comparison to the original film image to make sure it's as close to identical as it can get before printing a master copy. The problem with any digital process, whether it's DI or DP, is that it's still trying it's hardest to reach the superior quality of the original filmed image. Therefore, Film is higher quality and it's also the fundamental basis from which all digital manipulation and projection try to emulate...because it's better. You even said so yourself, and your only reason for supporting digital is you're annoyed about film damage and want to eliminate projectionist jobs, apparently.

    "But once principal photography is over and those images are on a computer, there's not much point to printing it out on massive film reels."

    Yes, there is--the superior quality of film and film projection. Film is organic, so yes, it degrades over time. And the reels are not "massive." All digital is doing is trying and failing to replicate the superiority of film. It's better to preserve as many non-digital methods as possible due to their superior quality. I get it...your projectionists suck. That doesn't mean film projection sucks.

  6. "If production companies and theaters can ultimately save money by distributing and displaying the finished product digitally, why not?"

    Theaters won't be saving any money. They're going to be losing more money than before. Also, the upkeep on a film projector is way lower. Anything mechanical is cheaper and easier to fix than something that is primarily computerized. Here's another way to look at it... you ever have problems with your computer? Does it just seem to not work right sometimes for not apparent reason and you just reboot it to find out it magically fixed itself? Now picture doing that while 200 people are waiting for it to come back on. It takes at least 10 minutes to reboot the digital system, and what if there was a power outage...now someone has to fast forward everyone's movie, and they can't do all 20 at once so you're looking at longer delays. Maybe you'll luck out and that computer didn't lose its place, but maybe not. The computerization of everything has removed the human element, and it makes for a much less enjoyable experience.

    "It seems like the only people who will notice or care are projectionists."

    you mean all those people out of a job during the worst recession in recent times? yeah, no kidding.

    "There might be more warmth in an analog recording, but since I'm going to be non-linearly editing on a computer, it doesn't make sense for me to master a recording and distribute it on cassette tapes. Everyone's still going to want a CD, high-quality MP3, or lossless digital format."

    It does make sense if you want better quality. All that's happening is an attempt to replicate the original master recording, and when that recording has more detail than the format you're using to listen to it, then it fails.

    "I still support shooting movies on film. But I don't support the expensive and archaic tradition of distributing and displaying movies on film."

    Take it up with Christopher Nolan. He thinks you're wrong too.

  7. Choosing not to support the expensive and archaic tradition of distributing and displaying movies on film isn't exactly something I can be right or wrong about, and Christopher Nolan has the right to disagree with me. Basically what I am gathering is that the main reason we don't project movies digitally is because the technology isn't quite ready to do it at the level of quality that we're used to. So that answers the question, "Why do theaters project film reels instead of digitally?"

    Because I foolishly did little research into the physics of projection when I crapped out this article more than a year ago after being talked into seeing some dumb film, I appreciate learning about the difference between the quality of film vs. digitized imaging. It's good to learn new things.

    When I say the "image is fundamentally digital," what I mean is that a digital image has been placed onto film for viewing in theaters. If you could magnify one frame from the film to an infinite scale (like I erroneously claimed is possible in the article), you'd see pixels. Sharp edges, blocks, right angles on every bit of information that is creating the image, despite the fact that the images were captured on film and are being displayed by light shone through film. If the images on the film are pixelated, then the image is fundamentally digital. This means there isn't an increase in quality of the image by projecting from film, because the degradation of the original image has already occurred.

    But as I said before, I've been involved in the analog vs. digital argument for more than a decade, and I know how everyone picks a side. I happen to be in the digital camp. Anyone who has a fondness for analog recordings, even those found on 1/4" magnetic tape, are going to prefer that method of data storage over digital methods.

    The issue is subjective, and everyone's right. The format that looks/sounds the best is the one you prefer. And it looks like a lot of theaters are now showing films in DLP, so I guess this article is pretty much dead now anyway.
