Normal (35mm) film projectors are roughly half this size. The film is half as wide, about a third of the length, and it runs about a third as fast as this.

I am not against there being digital theaters to bring down costs and to make it easier for movies to be shown but the theaters should also offer a special experience. So that should mean that film is offered as well to customers for for the big special movies. I would have prefered to have seen Dune on 35mm film than on digital. The same for Top gun. I am not talking about the cameras in terms of film but celluloid projection so the movies could still be shot on digital cameras.

Not even close. 4K still have picture issue unless the moviemaker do it right way.

@@srijangupta6404 KZfaq comment section is not the place to ask for advice like this.

@@srijangupta6404 Measure your viewing distance. Assuming you're going for 4K, that should be your screen size. Halve it for 1080p, double it for 8K. Getting the best picture quality out of a projector requires good light control. Basically, nothing at all should be shining on the screen other than the projector itself. Not only do you need to block any windows and make sure there are no other light sources in the room, the room also needs to be black to prevent light coming from the screen from reflecting back onto it.

@@KingdaToro @Adam Ahmed yes, we have hired an engineer, he suggested that we should get some dark acoustic panels, to control the ambient light, but i think that wouldn't be needed if i buy tv

Its 8k...two 4 k projectors ....but 70 mm clarity is super..

@@anoopjose6208 Ha! The source is 4k and most imax movies aren’t even shot in 4k anymore anyway. The entire imax laser system is incapable of playing back 8k media. The 2nd projector is only used to soften the image slightly so you can’t see the pixels. It’s also used for 3D which is a dead thing anyway. When Imax sold its soul to millionaires seeking to make money, the format died. There is no better quality format than 15 perf 70mm. Resolution is upwards of 12k at the print. It died due to IMAX not having anything to charge their theaters for since the film projectors were bullet proof. So make a new format that requires constant updating, charging theaters millions of dollars every few years to update, way more then the salary of projectionists and dilute the format so it’s nothing special. Then charge 2x the ticket price. It worked for a while but it’s not working anymore. Now everyone regrets getting rid of their film projectors and to top it off IMAX is making new film cameras. The battle for film is not over yet.

@@jasonst-louis7849 Strange indeed 🤣

The screen is what's called "acoustically transparent", it's full of tiny holes, too small to see from the seats, that let the sound through. You can see them if you walk right up to it. The thing that puts out the most heat by far is the actual lamp (lightbulb) for the projector, as it uses at least 5000 watts. Its heat is exhausted out through the roof, similar to a clothes dryer. The IMAX lamps are 15000 watts, and have to be water-cooled, air cooling isn't enough.

@@KingdaToro detailed and very interesting, thank you!

@@KingdaToro Imagine what IMAX could do with 35mm film if they really put their minds to it. They could probably have really exotic processes like using laser light sources for the film projectors. If IMAX, Kodak and a few other players got together they could probably do some really special things with 35mm film for large scale special theater showings.

35mm film projection is still far more impressive than any digital theater projector. And there would not be any cost difference between them.

You didn’t watch to the end did you? The 2k projectors were temporary. In 2016 they removed their film projector to make room for the huge downgrade of a 4k system (70mm film is approx 18k resolution and the difference is *very* visible at IMAX screen sizes)

IMAX theaters should really have a rotary woofer as standard equipment. Ordinary subwoofers fall off sharply below 20 Hz, rotaries are the only thing that can effectively cover the 0-20 Hz range.

​@@KingdaToro I'll paypal you 1000$ if you find me a woofer that can produce 0hz

@@julianklietz6558 As I said, a rotary woofer. It's a subwoofer that uses a rotating fan, instead of a cone, to move air. Like this: kzfaq.info/get/bejne/e51yntWq1d7eo2g.html The pitch of the fan's blades is controlled by an ordinary subwoofer voice coil, so they pitch back and forth, and push air into and out of the listening room, according to the audio signal. They're able to effortlessly cover the entire 0-20 Hz range because the fan makes more revolutions per cycle of the audio signal as the frequency drops. If you were to feed DC (0 Hz) to an ordinary subwoofer, the cone moves in or out and stays there doing nothing. If you were to feed DC to a rotary woofer, the fan's blades would pitch one way or the other and stay there, and the fan would constantly push air into or pull air out of the room. So, yes, it can indeed do 0Hz. It's all about excursion. That's the distance through which a speaker can move, and it's what limits normal subwoofers to about 20Hz. But with a rotary, the "excursion" isn't the distance the cone can move, but rather how far the fan can turn during each cycle of the audio signal. At 20 Hz it will only do about half a revolution, but at 1 Hz it'll do 13 revolutions. The effective excursion increases as the frequency decreases, which is exactly what you want in a subwoofer. And at 0 Hz, it has effectively infinite excursion.

​@@KingdaToro It can produce a 0hz tone?

@@julianklietz6558 Yes. A sound wave is just air moving back and forth at a certain frequency. A 0Hz "tone" is just air moving in one direction continuously. Of course it can do that.

You're right, it wasn't a minor upgrade, it was a major downgrade. IMAX film is roughly 12K-16K, and they're going from that to 4K.

@@KingdaToro Thank you for input. Is there better IMAX digital available?

@@SJR_Media_Group We don't yet have any digital system capable of projecting IMAX resolution, so digital IMAX does not exist yet.

@@KingdaToro OK, thank you. Hard to beat something that is near perfect. Is digital cheaper to shoot, store, and play than 1570?

@@SJR_Media_Group Yes, by far. IMAX is hard to use, the cameras are so loud that dialogue can't be recorded on set. The film is expensive, the cost of a single release print is somewhere in the five figure range, to say nothing of the film stock needed for a shoot. But the point is, when you buy an IMAX ticket, the premium you're paying is going toward all that. "IMAX Digital" is purely a scam, because the studio and theater are just pocketing it instead.

They almost did

To be fair, the quality on a phone with a 1440p OLED screen is better than the TVs most people can afford in 2022 and far better than the crappy low-budget cinemas we have here.

Someone just wrote IMAX on it with a sharpie.

lmao

there's literally no difference between 4k and 8k on it's quality.

@@miles5600 It absolutely will. It's all about the ratio of screen size and viewing distance. To see any difference, your viewing distance needs to be closer than the diagonal screen size. To see the full benefit of 8K, it needs to be half the diagonal screen size. In a proper IMAX theater, all the seats fall within this range.

@@KingdaToro 8k tv are already around and have been for a couple of years. Also you can now get Imax home cinemas

they had the downtime to make the upgrades, but they didnt. like restaurants that needs full refurbishment

Also, 4k in theaters is not the same resolution as 4k televisions

In the big cities yes. The main problem is the lack of content for the cinema that would attract people. Hollywood simply is not producing movies like they used to. The Oscars is a prime example of that were TV movies are not starting to dominate the awards.

for everyone except the patrons seeing as ticket prices are the same. (including "inflation")

The problem with 70mm IMAX was that they simply did not have that many movies to show on it so it meant it was a niche market. If the studios and IMAX and maybe other theaters had of focused on 70mm imax and standard 65mm they could have saved their industry.

0's and 1's in other words crap.

IMAX stands for maximum image, the largest screen possible with the highest resolution possible. To upgrade doesn’t necessarily mean technically a better image, open to debate, but rather a more economic mix of present technology to maintain a business into the future.

Italian

@@jasonst-louis7849 What Italian?

They are screen shakers and they cause the screen to vibrate a little to reduce the hotspot (glittering effect) on a silver screen. Without screenshakers that screen would look like a Twilight vampire.

@@andreasvogler1875 omg! this makes so much sense. we went to a cheap movie theatre once and it had this glitter effect. I was like WTF. Not only that, but the entire movie was pretty dim. Terrible experience. However, for the price, I guess you get what you pay for.

Sydney IMAX had a 1000m² screen size and it was the world's largest cinema screen. I went to it a few times and it had the most impressive screen image you could ever imagine.

Hi, I left after the 4K Laser was installed, at that time all the 1570, support equipment and film library were still in the booth but not in use. This was over six years ago, with it all just sitting and the Laser fully engaged, I would say there are many reasons 1570 will never be seen again at this theatre.

Sad. Laser still doesn't look as good as 70mm and there's a lot of 70mm footage thag won't be remastered for laser. An experience lost to time for no good reason. They already had it setup to swap between 70mm smd xenon, just keep that and show 70mm where applicable.

They wouldn’t just throw it out. Right?

@@robertforster8984 seems they get moved to the side, slow making it harder to bring back up. After years of non use too much maintenance needed to use again. Then it'll be sold off/disposed of to free up space.

Those are " screen shakers " essentially a subwoofer that emits a low frequency pulse to "shake" the screen. This is necessary in Laser projection as laser light will create a shimmering effect know as "speckle" as it reflects off the silver screen. They're mounted 4" from the screen on the scaffolding behind the screen, and there's about 84 of them! Lots of fun when voltages go haywire on one 60 feet up, sounding like a very happy cat. In this case we usually cut power to unit and wait until the following IMAX service.

@@whitcwa very interesting! How about digital movies and the way they are transported and displayed. I once, approx 8 years ago I had a behind the scenes in a movie theater nearby. Back then they used all the latest technology. So modern, they even now play movies from a USB shipped by the film studio. Is it just that easy? Is there really a USB with properly the best quality -(in terms of resolution, FPS, etc) -compared to Netflix, just in a theater? How come modern theaters don’t get robbed so often. Wouldn’t it be worth thousands if you had such USB? Orrrrt, is it not that easy after all?

@@TVARecordings They have crypto coding that locks the USB device. The projection system decodes it on the fly just in time for projection to prevent copying and theft.
