Addendum for people who’re interested 1) IMAX had 3 projectors which could do 15/70 - GT, SR (Single Rotor) and MPX (Multiplex). SR was cheaper in two discrete units for 3D, and one was fine for 2D. The TCL Chinese Theatre used a single SR unit for the 70mm presentations for Oppenheimer and Dune. Not GT. MPX was a cheaper version made in 2000s for South Asian countries and multiplex retrofits 2) The real reason why IMAX Digital is 1.90 is because Texas Instruments doesn’t make a DLP projector chip of a higher resolution or a different ratio, and 1.90 is the max as per the DCI standard. 3) IMAX Laser also has 3 variants - Dual Laser, Commercial Laser and XT - Dual Laser is able to do 1.43 due to a special anamorphic lens which desqueezes a 1.43 image from a 1.90 DLP readout - CoLa is the one BFI uses, custom designed by IMAX without a prism and two lens outputs for 3D, both L and R images are projected simultaneously in a vertically stacked manner - XT is basically again a cheaper but newer laser projector which has a single lens output and alternates each frame for 3D XT can have 12ch or 6ch sound depending on what contract the theatre takes up.

IMAX 1570 is still the gold standard.

The XT laser was another single RGB laser projector (newly installed at IMAX Blackpool) introduced in 2021 and was based on Barco's SP4K-40 projector, not sure which one the single COLA laser is based on which uses a dual head for 3D, the GT Grand Theatre is based on the 6P Barco DP4K-60L RGB laser projector. I prefer using a single head and the dual XT system could be done as a dual projector system and used in the same way as the GT to have one projector dedicated for the left eye and one projector dedicated for the right eye, as well as doubling brightness it allows doubling of the frame rate.

Amazing video Kim, so informative.

You missed the ones no one knows: imax SR, imax HD and imax XT Another weird thing is that you chose traumpalast photo to demo 1.43

another great video! keep it up! Kind regards Keith

The domes can play movies, force awakens was shown in a few of them

And there is 3rd generation IMAX with Laser project called IMAX XT, which uses 5.1 audio. The 1st IMAX XT was built in Shanghai, China, 2021.

La Geode is an omnimax in Paris due to reopen soon after closing for refurbishment in 2018 - I think they’ve kept the dome, it would be amazing to see a tour!

Thanks for the informative video! Loving the visuals provided in this one Bored_tech All the best with your future content, Rayhaan (IMAX Vanguard)

Hello Mr. Bored Tech, thank you for making and sharing this video. That's a great video! First of all, I would like add some information about IMAX sound formats and IMAX with Laser technology. According to Giant Screen Cinema Association about IMAX audio mixes, there are three types of IMAX sound formats: 1. IMAX 5.0 (IMAX Digital Xenon, 1.90:1 Aspect Ratio), please note that some IMAX Single Laser Theaters are limited to IMAX 5.0. 2. IMAX 6.0 (IMAX 15/70 mm Film, 1.43:1 Aspect Ratio), please note that IMAX 15/70 mm Film Theaters can play IMAX 5.0 mix version (separate audio track, 15/70mm audio version) too, depending on the sound mix of movie. 3. IMAX 12.0 (IMAX Laser), please note that some IMAX Digital Xenon Theaters are installed with 12-channel sound system plus sub-bass system and capable of playing IMAX 12.0 content. And of course, those three types of IMAX sound formats do not have dedicated LFE channel in the mix formats. There are also three generation of IMAX with Laser Projectors: 1. First Generation, IMAX GT Laser Projection System (4K Dual Laser Projectors, 1.43:1 Aspect Ratio, each projectors has single-lens); 2. Second Generation, IMAX Commercial Laser (CoLa) Projection System (4K Single Laser Projector, 1.90:1 Aspect Ratio, CoLa Projector has dual-lens); 3. Third Generation, IMAX XT Laser Projection System (4K Single Laser Projector, 1.90:1 Aspect Ratio, XT Laser Projector has single-lens). Thank you very much!

Great video, thanks. Can't hear that tech stuff about IMAX often enough 😅

Thank you for making the video!

Whats up with the mixture of subs? I see typical 4×12" Eminence subs, yet directly below them I see what appears to be 18"s ... Any thoughts? Also, showing the small ceiling flown clusters, it appeared as if they were Danley Synergy designs.

Cinesphere is actually fitted with a regular screen rather than a dome, it's also the first permanent commercial IMAX theatre there is! Great vid as always

Thank you my friend.

its a shame BFI didnt get the dual laser when upgraded after taking the waterloo site control back from odeon, i suspect cost was an issue. as BFI IMAX has better seating options than EMPIRE Leicester sq dual-laser-IMAX(which only has 3 usable rows)

Thanks!

Great T shirt!

Try contacting the Planetarium in Copenhagen, they have an IMAX Dome screen, and they have been showing OmnIMAX/IMAX Doma since 1989 so maybe they also have the old 35mm sound playback machine.

It would be very awesome to see a imaxdome backstage tour

My life was forever changed when I experienced Adrenaline Rush in the Omnimax in Vancouver as a child. It blew my mind!!

what about xt laser?

Love the Cineworld IMAX leicester the sound is soo powerful you could fee the thumper in your chest in Dune 2

Would you consider doing a cinema review of Manchester Printworks?

Can someone confirm what type of IMAX is at the regal transit IMAX in williamsville NY ?

IMAX 1570 film format: IMAX 65 millimeters horizontal negative (1570 horizontal print) 70.41 × 52.63 millimeters frame 11,734 × 8,771 = 102,918,914 digital equivalent pixels resolution

Btw I know Mr. Ford and been in the booth two times, before and after works

Ask them what is the crossover (hz) for IMAX 12.0 bass management
