Beginning today the film aficionados of Los Angeles will finally be able to watch movies in one of the most storied theaters in the country without sacrificing seeing it in the best format possible. The TCL Chinese Theater, originally Graumann’s Chinese Theater, has been retrofitted to house one of the largest IMAX screens in the country. With state of the art digital IMAX projection, added stadium style seating and a custom built sound system, TCL Chinese Theater is now a destination worth fighting through tourists and costumed panhandlers to see.
To accommodate the new oversized screen in the historic landmark, the company dug out the floor of the cinema and went down through the original orchestra pit and basement. Luckily the floor and seats had been modified before the Chinese became a historic landmark, allowing it to be dug out and retrofitted. The theater is reopening this weekend with one of the films it had given a red-carpet premiere in 1939, the IMAX remastered, 3D upgrade of The Wizard of Oz. We talked to Brian Bonnick, the Chief Technology Officer at IMAX, about the companies push to lead digital projection, the upgrades they’ve done to the TCL Chinese and how servers are replacing projectionists.
NERDIST:Â IMAX shifted gears toward being a leader in digital projection about six to eight years ago. What steps are you taking to insure that you’re leading the way?
Brian: I think that a lot of what that is⦠really comes from the filmmakers. Theyâre the best customer and the best critic. Theyâre the ones that get what makes a good experience or what doesnât make a good experience and the thing we always look at nowadays, or whatâs everybody talking about, is that they talk about prices, prices are important, or they talk about resolution and resolution is important but by themselves, they are just two variables. I think we try to take the more organic approach and say: what are all the things that work together to make a better experience in the theatrical environment and can we tackle each and every one of them. My analogy would be a car. We both go out and buy a car but I go and change the exhaust, change the pistons and I change the timing. Any one of them by themselves give me a little more horsepower but if I start doing them all, I start getting a better car and a better experience. Itâs that analogy weâre trying to do. So weâre in there everyday, weâre looking at things saying: what can we make work better than what it does now.
There are some things on our list where we donât know how to do it yet but maybe it two years time we can because technology can change. Our laser system is a good example: we designed a component and I couldnât find anybody in the world to build it to the tolerances that we needed, so we had to say, hereâs the design we can implement down the road and weâll implement this design in a slightly more costly and complicated manner. I can still get from A to B, just not in the cool way I initially thought I could. So itâs those things like that weâre constantly looking at that you have to focus on and consider. That contrast is so important to the filmmaker and if you look at whatâs happening in the industry right now, in my personal opinion, is that people out there are pushing a whole bunch of new things for the sake for generating revenue, which is fine, people need to do that, but more is not necessarily better in all these different areasâso how many speakers in a room is the right number?
NERDIST: You said that the sound in this particular theater is acoustically tuned to maximize the efficiency of the space and this is a theater thatâs known for having amazing acousticsâthey’ve had full orchestras – then you have systems like ATMOS which are getting built into some IMAX theaters and you see some changes in these super theaters. Whatâs the benefit to being able to approach it the way you did here, versus having a chain say, well we want to be able to add this feature and this feature because itâs a part of what weâre building as a chain versus the IMAX approach?
Brian:Â A chain can do whatever they want and the way I look at it is: if somebody else is doing something that has merit, I donât have to be the guy who thought it up, I think itâs a good idea to implement. So, for example, we pick the loud speaker. Our laser system will come out or our next generation sound system will come out, and we will have some additional loud speakersâtwo on the sides and weâll have ceiling ones too. The one on the sides, funny enough, are a value to us because with a large volume venue like this, because of this technology we use in our loud speakers, proportionally point source technology, we can create phantom image. The other loud speakers you see in the wall thereâthe sheer size of them, theyâre not full range, they donât have dynamic range. You can only get so much out of something like that. (4:20 ?? right off the bass), so what if you get tons of it, youâve lost something else. Now, the benefit of having many like that, is that they will mix the track so that they can create a sound from a particular point. Thatâs a real positive thing but we can do the same thing but we do it a different way, by using phantom imaging, and that goes back to how you design the loud speakers. So our belief is that you want to reproduce sounds the way it was recorded, which means that you need to have full dynamic range, which means that every loud speaker through that room has to be a full range loud speaker. It canât go from 100 per side and count on just your sub bass to fill in, itâs got to go down quite low so then your sub bass will cover the really low range.
NERDIST: Projection in the exhibition industry was very stagnant for a very long time. It was like this is how you do it, you were showed by the union guy and you were an operator. But digital has created, for lack of a better term, a bit of a land rush. You are doing an amazing job of being just ahead, right now ,and a lot of people are then mimicking your processes. Whatâs your commitment to the theaters about upgrading as you find a better way?
Brian:Â We do it all the time now. We sign contracts with the clients for a multiple period of years and we support that while they break through that. Now, that doesnât mean weâll come in and put in completely brand new set of loud speakers when the next generation comes out, for free. On the other hand, is the example with our tuning system. It has gone through multiple alterations and enhancements as we develop new algorithms and those automatically put it in the systems, so weâre constantly upgrading clientsâ systems. The big thing that we have done is, when we first started doing digital, we had this network operation set up so we were collecting data. We were collecting it more like everybody else: Does the system have a fault? Iâll get a [notice] sent to me saying it wonât boot or something like that, but Iâm also going to find that out in 20 minutes when I get a call from the client. Weâve completely flipped that around saying, weâre one in eight who collect data. We donât even know why weâre collecting, we jokingly said that we were monitoring the CPU temperatureâwe do, we can tell you the temperature of the system everyday since it was installedâbut what I canât tell you today is why Iâm doing that and I may never be able to. On the other hand, the example I use for measuring current of the fans, I didnât know why I was doing that either, but suddenly we were able to, on a preventive basis, looking at why things failedâis there a trendâand then suddenly you realize, âWhoa, Iâm collecting a piece of data and I know how to use that.â Not every piece will be done that way.
The other side of that is preserving the quality of the presentation and before you know it, you can put in a system and tune it. Then again, other people are coming up with new sound systems, but not one of them is talking about how to tune them. So, I can give you a billion dollar set of loud speakers in your home but if I don’t tune them properly, they sound like what your car sounds like and in a car you can have one car that sounds awesome and the other, not so good. Having been in the business, you know you go into one theater and it sounds great, an acoustical system, but others don’t have specs like you do. We adhere to these specs. So one, the room has to be treated before equipment even comes in, and when we tune the room, the others come in, for example, theyâll take the microphone and swing it, and theyâll walk down that center aisle and theyâll take readings and theyâll use an equalizer, that has a 31 band equalizer for each channel. Great. If youâve ever looked at the frequency response, they are so much over the spot that youâll have 31 graphic equalizer or maybe some parametric bands, if theyâre lucky, maybe four or five. Our system collects tens of thousands of data points from over 20 locations within the theater so now weâre dealing with mobile analysis to get rid of those, âI sit here and I canât hear the bass and I move here and suddenly I get the node and hear the bass louder.â We try to minimize that as much as possible. But more importantly, Iâve got over 800 points that I can adjustments to slightly. So, I can take that response curve and now Iâm not only say that I can pick the 31 worst peaks and valleys and fix those and say, Iâm done, I have 800 places to play with and weâre actually increasing them even further and then weâre using algorithms that put substantially more intelligence into this tuning system. At the end of the tuning process, we still do the proverbial âgolden ears will listen to it and make sure that what weâve done is under a computer software is accurate,â we donât totally rely just on push a button and itâs all good. You always have to go and listen that youâve done everything right. The other things we worry about are matching loud speakers. Your ear is extremely susceptible to noting differences in frequencies. So, if Iâve got 64 loud speakers throughout this room and I play a tone from one to the next to the nextâthat same toneâand see if you can see if the volume and the frequency is identical of each. The answer is no, they wont be, because what happens there is that youâre coloring the experience. What weâre trying to create is a pure experience and not color it.
We even tried testing the shape of speakers and the funny thing was, when we tried that, some liked it and some didnât like that but what we realized is that itâs not reality. Reality is that low frequency sound coming into your body. So, lets go and design some bass speakers that go lower in frequency than anything thatâs ever been used in the industry because thatâs how you reproduce a natural low end sound like a rocket ship taking off. Thatâs how you hear, you hear through your body not through your ears. Weâre really trying to take a very purist approach to it.
More is not necessarily better and you have to be careful, especially with special effectsâstuff on the ceiling and things beaming aroundâthatâs cool, but for the greater part of stuff, 3D is a good analogy: Remember when it first came out, every shot had that 2 by 4 and when you watch it now, you go watch an IMAX film, one of our documentaries, they bring objects from behind, from infinity, literally, up to right in front of your face; thatâs partially because we give you this massive field of view. We draw a line from the tip of your nose to the four corners because 3D can only sit on those corners, so if that screen is very narrow and far away, youâve got a very narrow 3D viewing range whereas if it were wide, youâve got a much broader one, you can bring things that much more realistically out of the screen. When you bring things out of the screen, you create anomalies, you create a ghosting problem. So whatâs everybody doing now is push images out of the plane of the screen to behind so when you take of your 3D glasses, it doesnât actually look 3D. It works for the general population but it doesnât necessarily reproduce content, not everything sits at the plane of the screen or behind it, things do come forward of that convergence point. Those are philosophical things. There isnât a right or a wrong, thereâs a way we look at things we thing weâre trying to reproduceâvisual experiences and audible experiencesâthe way they occur in nature, the way they should be. Then there are other ways you can do it and again, I donât think you can go so far as to say that thereâs a right or wrong because I donât think there is, there are just different experiences. Weâre trying to reproduce reality to the point where if youâve never been skydiving, perhaps our theater is as close as youâll get to experiencing that guy jumping out of that plane and feeling a little sick in your stomach, and I think thatâs cool.
NERDIST: You get so much data from this system that itâs kind of incredible, you could really use that data to do everything from how to build  out that theater for maximum acoustics in the theater or you could use it to just tweak your own systems⦠where else do you see that data going for IMAX, do you see being able to use that and move into other ventures?
Brian:Â Like other market opportunities? Oh yeah. If you take a look at our image enhancement technology, there are opportunities to use that, in my opinion, in a whole bunch of fields such as restoration. The byproduct of our digital mastering technologies is that it removes data that you donât want. Youâve taken your file thatâs this big and youâll make it this big. So, you no longer have to compress it and therefore, there are opportunities to use that in standard broadcast. You run your content through this thing and not only are you enhancing it but youâre making it smaller. And when you jam it down the pipe to your home, itâs not being compressed as much and youâre not having the same compression artifacts, and therefore, you get a more pristine image. So there are all sorts of things of that nature that you can do. A lot of stuff we want do, or what Iâd like to do, you can do post, I want to do it real time. Thereâs an image enhancer and right now, what we do is, if you can compare it to any other system, put a brand new lamp in your projector and you get the DCI spec of 14 foot-lamberts, what happens is that that lamp degrades and that 14 goes down to 10, it goes down to 9, and for some operators itâs money, 8, 7, 6, so let it go. Which is an oxymoronâwhy is everybody pushing more brightness when nobody takes advantage of whatâs available today? In our system, they canât do that, weâre 60% brighter with 22 foot-lamberts to start with and our system is designed, with that camera, to monitor whatâs coming off the screen. So if the screen gain gets reduced because of dirt in the theater, if it goes from 2-4 to 2-1 and youâre not getting as much to your eyesâour system knows that because itâs not seeing much, itâll adjust. As your screen degrades, our system takes that into account. Nobody else does that. So weâre guaranteeing to you 22 foot-lamberts for the life of the lamp and when that lamp finally hits that point of no return, and it just canât meet that number, we get an alert and weâll phone the client up and say look, you need to change that lamp. And if they donât, Iâll make a decision, I may actually choose to send somebody out to change the lamp, deal with the financials at a later date and ensure that our brand reputation isnât tarnished because people are now watching something that doesnât represent the quality experience that you get in IMAX.
As soon as we start letting stuff degrade, we lose that differentiation so thatâs why weâve invested so much money on how we monitor sound. Some theaters turn down sound and the questionâs well, why? Youâll get the odd irate customer, thatâs going to happen, that’s fine, just make sure you turn it back up. If thereâs a problem, is it the soundtrack? Is it something in our theater? Do we have something not working in our theater? We want to know about that. You don’t want clients walking out and that’s why at the end of every single IMAX movie, the credits come by and thereâs a statement that says that if thereâs anything that you didnât like about this, call this number or send an email here and we will respond. Itâs the little things. What weâre trying to do is make sure that every single show is as good as the next and every theater is as good as the nextâwhere the acoustical treatments are critical. I donât want you going into an IMAX theater and say that this one is way better than that other one or that it sounded way better. It shouldnât. Thereâs always some anomaly some variation but we donât want very much of that because theyâre all representing the IMAX experience.
And you can get that IMAX experience at the upgraded TCL Chinese Theater in Hollywood starting today for the Wizard of Oz IMAX 3D.
