OPPENHEIMER 70MM IMAX film print assembly at Science Museum, London.

[@eggydrums]

You are doing God’s work, friend. I’m glad that directors like Nolan have helped kept traditional film alive. I sense that Oppenheimer will help push this further into the mainstream.

[@boredtech]

Thanks a lot, I'm glad it was interesting for so many people. I'm hoping that Nolan will get his OSCARS finally.

[@thischannelisdeleted]

@@boredtechPLEASE keep it alive! PLEASE make it come back to mainstream! It is my dream to shoot a movie in 35mm.

[@maha-madpedo-gayphukumber1533]

It's super quality work. But I dont why they don't wear gloves while handling such sensitive imax film. They are handling with bare hands without gloves while joining the reels . But some time they are wearing gloves as it shown in this video. But first guy dint.

The unfortunate thing is that many filmmakers want to use film. The studios don’t allow it though.

this is so cool, thanks for the video! i’ll be watching oppenheimer next week and it’ll be my first time watching in imax, much less 70mm, which is so exciting

[@boredtech]

You are most welcome! I'm sure that's going to be epic experience. By the way, I was so busy editing this video so I didn't book my tickets yet, not sure when I'm going to see it now 😂😂😂

[@ClarkTeddles]

This video was absolutely brilliant. Thank you for making such a wonderful and in depth video on this process. Was brilliantly filmed and edited, great job! Have a great day. Can’t wait to see this film in 1570

[@ClarkTeddles]

@@NotMe-bk9oifirstly, I greatly appreciate that you said IMO. Imax dual laser certainly does look pretty darn brilliant. That’s very interesting that the sharpness was better in another cinema, perhaps it’s something to do with the kind of screen they are using? So much can go wrong with these screenings that it’s quite hard to tell these days.

[@marshallwebber9682]

As a former projectionist (35mm) I REALLY approve this video!

[@boredtech]

Than's a lot! Appreciate your feedback very much!

[@bilespitter]

same, gave me big nostalgia despite only ever working on 35mm

[@WhoFlungPoo2024]

Phenomenal and beautiful editing on your production. I'm a former 35-mm IATSE union projectionist in the U.S. I come from the days of carbon-arc lamps and 15-minute reels. I left the business around 1983, when automation and platters were introduced and closed out my career in automated booths. Comparing this to what I've experienced, it's the difference between the Model T to an Airbus A380. I especially liked the zig-zag splicing technique to increase the contact surface. Pure genius thinking. I will be seeing "Oppenheimer" in 3 days but I believe our local IMAX house does not run print and, I assume, is digital IMAX. With projection what it is these days, I have a hard time imagining other than a highly-skilled technician putting together this amount of film and especially given the expense and the pristine treatment is must receive. Kudos to you and my booth brother in Kensington!

[@tommyknchan]

it's a very detailed explanation of joining the 70mm IMAX print! salute to the projectionist professionals!

[@alextgordon]

10:40 I love that there's a very mechanical limit to how long a director can make a film

[@jfbeam]

Until they need to move the arms out. ;-) They can always do it the old school way, with multiple platters.

[@shApYT]

That's why we have intermissions. There is so much more to the Oppenheimer story. It could have been 4 hours.

[@mumiemonstret]

As an old 35mm projectionist, and also as a fan visiting London in a couple of weeks mainly to experience my first 15/70 Imax screening, I was super happy to have this insight in the booth! And I am also happy to learn that the length of Nolan's movies has finally reached its physical limit! 😄

[@rsr789]

I'm going to go see it in the only IMAX 70mm theater in Florida that's playing the film. Tickets are selling out faster than a Pu-239 chain reaction.

To me Leonberg and Prague are the same distance, so I chose Prague for the 15/70 experience

Wow! I wish I had access to see 70mm imax! I’m going to drive an hour and a half to a theater tomorrow to see Oppenheimer in Ultrascreen Dlx which Iv never been to before instead of going to a plain old crappy theater here.

[@josiahsimmons9866]

I appreciate that the reel was blurred. Even if the scene on it was inconsequential, we're still getting absolutely no spoilers. Sadly, my city barely has a 35mm theater (alongside some digital imax) So no 70mm or 70/15perf for me 😭

[@Khanstant]

[@trulsdirio]

Even tho I will only be able to see the regular 5 perf 70mm print, I am still really excited to see large format film being continued and hopefully having even more of a resurgence in the future! The theatre I will see it in is called Lichtburg (light castle) in Essen, Germany. It has a huge capacity seating over 1200 people and looks more like an opera house than a cinema with its 1930s styling and a huge balcony. It also has an actual stage and the biggest rolling screen in the whole of Europe. The stage originally was used for the orchestra back when silent films were still the norm. It was partially destroyed in WW2 and restored to its original appearance in the following years.

[@josuastangl7140]

That sounds awesome! I live in lower Bavaria and will be driving 3h to Prague, to see it in the only IMAX 70mm theater in the EU

Fascinating! This was a revelation for me; I had no idea just how complex this process is. I'm looking forward to seeing "Oppenheimer" next week at the Chrysler IMAX Theatre in the MIchigan Science Center in midtown Detroit.

[@BobNWFA]

@michaelrogers2080 After seeing "Oppenheimer" yesterday at the Chrysler IMAX Theatre, with a curved and distorted image, fuzzy focus, and truly horrible seating, I can verify that I will indeed be happier watching the film in the eventual Blu-Ray edition at home on my 65 inch screen with Dolby Atmos. Shame on IMAX for permitting the presentation of the film in the Chrysler venue.

[@owichmann]

I'm there on Friday

[@hartleydall167]

Incredible! Do you really need to blur all four seconds of film seen on the table?

[@PixPete]

Another excellent video! I would be really interested to know how they archive these films - do they just leave them on the platters, or remove them and pack away completely? What happens to a film when it's no longer needed? Some of these venues will do re-runs of old Nolan films so it would be really tedious to do all of the splicing and preparation work again just to run The Dark Knight or Interstellar for 1 evening?

[@strivingtobalance]

As a former projectionist, I enjoyed this tremendously. The closest 70mm is nearly three hours away, so I must settle for the lesser IMAX screenings in my area. Saddest of all, we have a 4K dome IMAX in my town and they are not showing it. Very frustrating.

[@LukeNVargas]

This video was released a week before the premiere. Don't you think that showing a frame of the movie which was not yet released all over the KZbin is a bad idea?😄 I wanted to make sure that I will not get a copyright claim from Universal Pictures.

thats what makes the projection difference.. it would be amazing to see this version.. I managed to watch it in IMAX but it was digital and not the 70mm, but I also did watch the 70mm not imax, and the combo of both would be mindblowing... the IMAX sound is what makes it, but the 70mm is definitely something your eyes should experience.

[@JAFOpty]

What I don't understand is why the reel is bigger, I know the area of each frame is larger, but shouldn't it have the same amount of frames as a 35mm movie reel? (love the vid btw!)

[@boredtech]

You are correct, 35mm film and 15/70 IMAX has same amount of frames, but… 35mm runs vertically and IMAX horizontally. 35mm frame height is 18.6mm and IMAX frame width is 70mm. It makes IMAX film reel almost four times longer than 35mm.

[@ReelFilm2016]

Great video. Fantastic even. I’m seeing the movie at the Odeon in Norwich. If I was still living in London, I’d have booked to see the 70mm presentation. You have a new subscriber.

I do not missing doing IMAX assembly... not that I ever messed it up but was always freaked out I would. There was another untrasonic weld version of doing the assembly as well using the zigzag method allowed you to later disassemble the print if needed which is why it is the preferred method these days. Granted last time I worked on IMAX was like 33 years ago!

I noticed the tapes having 'The Gadget' written on them, was this a reference to their nickname for the bomb or an imax specific term?

Exactly: Gadget was the code name for the first atomic bomb. Quite often while movie is in production they are using the code name for it too.

[@bedoublewide]

Why use a CD for the auido track? Would it not be easier to use a usb stick insteadd thus making it faster to copy audio to the HD?

Then you have to redesign whole system, test it, and make sure that it is reliable. And what is the gain, save couple of minutes once per couple of years?

[@URBONED]

I wonder if these thirty something cinemas get to keep these reels considering they’re specially made only for them or if they will have to box them back up and return to Warner Bros until they possibly play them again in the future.

With all the news articles and videos coming out about Oppenheimer and 70mm film vs. IMAX digital, nobody is covering this question: Which is better-(1) Watching the 70mm film version from a “bad seat” (which are fairly plentiful in a typical theater of this type, be it too close or off to the side), or (2) Watching the film in an IMAX digital theater from a good seat in the house, which I suspect is easier to reserve.

Going to IMAX Theatre in the Indiana State Museum, in Indianapolis. Booked three weeks in advance but was only able to get seats quite a bit to the side. It's a two hour drive. Shame that more theatres don't show IMAX but it seems to be quite an inconvenient process, plus Nolan is the only one who goes through all the trouble of doing all the editing via an analog process so 70mm seems to be a dying breed. Hopefully in the future we will be able to make things like 8k projectors more standard.

Would have been insightful to get some basic questions answered, like why does the reel need to be recombined in the first place? Is it an issue of shipping, is it that projection systems are so different between cinemas, or some other reason?

IMAX usually ship the film assembled in large silver shipping cases. Each large case can hold approx 1hr of film on a wooden board as in this video. Due to time constraints imax send some prints out early to cinemas who still have the staff who can assemble them.
