This video was actually shot several years ago. This location has since removed its' 15/70 equipment and is 4k laser only.

​@@jasonwhytemedia Thanks for the depressing update for this theater 😞

Sure, put this in every little theatre in Smalltown Village, not that it is any kind of major investment :D

@@SiljCBcnr I is a large investment and would not make much sense to put it in small towns for villages. But in Cities and large Markets and especially in older movie theaters that had a film projector at one. It would be a good investment to add a single film projector to the theater for directors who prefer actual film over digital such as Christopher Nolan.

@Max Pell Well said, but digital projection is only one of many nails in modern theaters coffin. Assigned seating and absolutely insane food prices are not helping anything. No one wants to pay $15 for a bucket of popcorn when they can get a whole bag for a few bucks, sit on their sofa and even pause the movie if needed. For theaters film provides a classic and unique experience and hopefully the ticket sales to the film showing of Oppenheimer are enough to turn some heads and see there is money in showing actual film. In my opinion and I am pretty knowledgeable in these things, there is no reason theaters who use to have film projectors can't have one screen with a film projector and use it to show classic movies and also new releases. As you said, digital will eventually be the demise of theaters as we know them unless the wake up and back track, and I don't see that happening. They still think digital is the way forward and no one can tell the difference.

Wow, thanks!

Hi, thanks for your question! Good observation on the methodical checking. I’m retired now but spent 45 years in a career of operating and repairing electro / mechanical equipment. The most common failure in this environment is human error. Most mechanical and analog equipment will tell you of pending problems. The most consistent reliable equipment in this projection booth is the 35mm reel to reel sound track and the 1570 projector. Maintaining a good service routine, familiar feel and sound familiarity is essential. As technology advances, the ability of operators to control consistent performance will diminish. At the time of this video we had comprehensive spare parts on hand, now the equipment in this video is ether gone or no longer used. This theatre is now 4K laser with very few parts on hand.

@@HughDenbigh May I ask a technical question. I worked as a 35 and 70mm projectionist in Israel. I always laced the 35mm film that the upper reel rotated clockwise direction and the emulsion side (matt) was laced toward the gate. I'm retired for 12 years. Now I watch all videos on KZfaq and see that all American projectionists lacing the film while the upper reel turning anticlockwise. Maybe you can explain to me why is that. Your video is the best one showing the threading film in the IMAX projector. Thank you.

@@HughDenbigh The old 1570 is more reliable than the new 4K laser unit?

The Boston Museum of Science has a similar setup.

That’s going back!👍

You'd have a lot of unused space for that. Ultra Panavision 70 is really wide at 2.76:1, while IMAX is usually around 1.3:1 (close to 4:3). Plus you'd either need a new print to fit the horizontal projector IMAX uses, or get a vertical 70mm projector in there with the appropriate lens.

@@counterfit5 what does 70mm imax means? Are imax films projectedbin a film projector instead of a digital projector?

Thank you for having a look and I’m happy you liked it!

Content like this is why KZfaq beats sat tv, cable, streaming, etc.

I hope this isn’t a stupid question, but do you need some kind of studies or degree to handle something like this? It looks like a lot of technical knowledge.

Hi, The brain lights or take off unit lights are indicators to the operator that the sensors mounted in the film gap of the take off unit are working. As you say red is indicating the drivers are slowing the patter and the green indicates a speed up, all very sensitive and quickly controlling the demand of film feed to the projector.

I aggree, but film countdown leaders arent really so important.

Yes, it's true. 4k laser IMAX only. The projector and some film prints are still there but mostly for display purposes from the outer window for museum guests.

It's a massive downgrade in resolution. IMAX film is roughly 12K-16K, you're going from that to 4K.

Digital projection is coming very close to film. Cooling for 1570 is water for the lamps including air for the housing, Digital projectors tend to use heat exchangers.

These days with home entertainment going digital all people have to do now is type in the name of the movie that they want to watch then push play on their remote.

"Disk"? That' some round thingy us old people used back in the day, right? ;)

@@josephbennett3482 😂😂 yeah now it’s streaming movies.

Facts! Prepare yourself for the typical generic "okay Boomer" response from a younger person, because they know what you said is true 😅

​@@trendmassacre8423 yea FCK the younger generations who have no say in whether or not movies are shown in film or not

What will be the cost of IMAX 70mm formats theatres in India or atleast can you give me few answers about setup of IMAX formats theatres in which ways is good

As someone who worked im broadcast video since its birth we would always say "one day film is go in by way of the dodo bird" it is hugely costly compared to video and now you can edit a feature length movie on your laptop and project it on a laser projector. Film still has its charm, but I bet most can't tell me why. Video cameras have reached the quality of film as far as dynamic range and resolution but its not that...

The dual 4K Laser projectors are a near duplicate in terms of image fit to the 1570 GT ... The smaller image of the digital 2K was a temporary solution to provide 3D until the 4K Laser was ready.

@@HughDenbigh Lemme guess: the Digital projectors are BARCO's?

Yes to a degree, along with a flat glass called a film flattener in the optic path before the projection lens. This glass is also used to remove any debris in the picture buy a quick vertical movement, up or down, controlled by the operator (opposite than film horizontal direction)

What will be cost of IMAX 70mm theatres in India or atleast tell me how much cost requires for setting up IMAX 70 mm theatres in India ?

Hi, 1570 film doesn’t contain any sound information. The 35 mm film is soundtrack played on what is called a dubber that has been largely phased out. In this video it is primarily being used as soundtrack for previews. All sound for IMAX 1570 is synced through frame count passed to and synced to sound equipment.

Those were Palms

@@counterfit5 Ahh, right

Magnetic

These are the only PTRs used, the colour changes over time from a light green when new to a dark burgundy from absorbing the photo guard on the film.

It is called a dubber, originally used for recording audio using 35mm magnetic coated film stock. By changing the head to playback, we used it for 48 min feature (documentary) sound tracks and trailer sound tracks.

The red beam that reads the analog audio track is below the aperture window for the picture, so the audio portion runs about 24 frames ahead of the actual image it accompanies. However the readers that decode the digital audio info are located on the top of the projector before the film image passes through the aperture window.

There is no sound information on a 1570 print, picture only. The sound is synced by following frame count. The film is loaded with the start frame sitting at the picture gate. Every frame of the film is counted, from start frame to projector stop. This count is interfaced to both the sound source and the projector control system by a mechanical spinning optical wheel housed in the projector. This mechanically tied wheel converts the count to a pulse. The sound source follows this electrical pulse creating a time code.

@@HughDenbigh Ahh, that makes sense! Thanks for explaining :)

If you look at 07:00 to 07:20 you will see I’m winding the film on the take up platter. Once the film is finished, it is ready to play again as the leader is in the centre of the platter where the film plays out.

The platter will stop spooling it out, lol

Lucky to have both still in my city

How to setup a IMAX 70mm theatres in India ? Do you know anything about this I mean basics information

Because it’s better resolution and colour when printed onto 15/70 film.

I don’t think this is true

Palm pilots are long gone, this was filmed 7 years ago.. at that time they were filling in for dysfunctional interface.

Yeah but it’s not as good as 15/70mm IMAX so it’s not ‘way better’ at all.

Yes, if your time is occupied only as a film editor. But in the world of operating a 1570 projection booth, no. The luxury of putting gloves on and off as you juggle tasks is quickly realized, futile. After 18 years of running 12 to 13 shows per day, 364 days a year with a constant changing film lineup, managing time safely and productively becomes paramount. The shipping and receiving of the film library is constant and arrives as new, needing of assembly, adding, removing trailers or repair. These tasks are often required to be done while running shows or even repairing equipment. The inside of a 1570 projection booth is not a quiet serene environment, a projectionist needs to be juggling and thinking of a hundred things at ounce and ready to jump. Remember, 1570 film runs past the projector gate at approximately 5.5 feet per second. What is important is that the splice and or repair of film damage is done correctly in terms of strength and maintaining sync. In all my years I have never and would never hear a complaint regarding a finger print or smudge on screen. The films are shown hundreds of times before scrapped, during that time a particular print could have gone through many repairs including black slugs inserted with virtually no notice on screen. At the speed of 1570, most imperfections are missed by most viewers. This is the real world of running a high volume Imax film theatre.

What will be cost of IMAX 70mm theatres to setup in india or normally how much it cost sir ?

Love it great information sir Please sir But give me few information how to step by step information to setup a 70mm IMAX theatre in country

Well, technically that's what the digital projector at the end does, even tho it's a bit more complicated as digital movies are encrypted and use DRM to limit when and how often the movie can be played. Still: Most digital footage is only what? 2k? 4k? Maybe 8k? While it is hard to compare analog media with digital ones you could say the old 70mm format is somewhat equivalent to between 16k and 40k and can be played as long and often as you want - with a technology over a hundred years old. (OK, not quite as often as you want as the film material wears down, but there is no artificial limit imposed by the creator/distributor)

The bigger the film frame, the better the image resolution will be. The bigger the screen is, the more image resolution is needed to keep the image sharp and clear.

They have 4K Duel Laser projector - they’re one of the first IMAXes in the world to get it. The projection quality is quite good and the sound is 12 channel surround sound which is better.

For waking neighbors THX should be a way better fit, don't you think? :D

Spatial sound is for headphones only. It mimics the Atmos room only.
