That will fit nicely in my 32gb micro sdxc the size of a fingernail.
Actually it won’t. A movie on a 4k blu ray is around 80gb without additional compression. And Oppenheimer is shot on 70mm which is more like 8k resolution. Still would fit on a micro SD of course
It’s way bigger than that. Usually cinemas receive movies in multiple terabyte hard drives. Thats because they are using JPEG2000 standard (it varies, but it is close to lossless) and a movie can take up anywhere from 500GB to 2TB (highly dependent on resolution, it can go above 2TB). https://en.wikipedia.org/wiki/JPEG_2000?wprov=sfla1
Some things to keep in mind about the theater experience.
- Only a handful of theaters do film IMAX anymore. A lot of IMAX locations are just 4k DCP (Digital Cinema Package)
- Most theaters in the world are digital projectors with a max resolution of 1998x1080 or 2048x858
Part of the reason these factors still exist is cost. A poorly maintained film projector with a lousy film print can ruin a movie going experience. Hollywood would sometimes release so very shitty prints. The digital projectors are much easier to maintain so the experience is often more ideal for the average movie goer.
Having said that, if a theater takes good care of their film projectors and they have a well made and well kept print, the experience can be amazing.
If you can see the film print in the opening week. Christopher Nolan makes his movies in an analog way. So it is a film process all the way though except for VFX. This is one of the only opportunities to see film that was not digitally modified. Only one place in the world can make these imax 70mm film prints and they are all basically hand made.

2k digital projection is typically used in smaller theaters where the screen size is not large enough for anyone to actually see a difference.

I didn’t realize imax was still film. I figured it went digital with everything else.
70mm film to be exact
There’s only a handful of IMAX theatres in the world that can play this format. Most of them are digital.
600 lbs ~ 272 kg
If I pay to see a movie in an IMAX theater, this is the film being loaded? Is this normal for IMAX?
No. This is called “15/70 Imax”. There are very very few theaters that have this. The “Imax” you’ll find at the local mall is totally different.
This obsession with the length and weight of the film is such a bizarre marketing strategy.
Yeah, we all know girth is what matters.
I assumed even an IMAX film would be digital now.
Imax film is some of the highest resolution formats we have it’s like 16k resolution, and using that for a projector gets ya some really good quality.
Quality so good they can come back to it 20 years from now when blu-ray is an outdated format to make a higher-quality home release, like what’s been done with VHS to DVD or DVD to BD
Kinda already is
I’m sure I’m wrong, but it’s hard to imagine this being better quality than what we can do digitally these days.
You are in fact wrong lol. Actual film has a resolution equivalent of something like 18K.
Wasn’t normal 35mm film about the equivalent of somewhere between 4k and 8k depending on the film stock?
Plus, the projector optics will always limit the sharpness of the picture. No lense is ideal, and even ideal lenses would have fundamental limitations due to diffraction.
Something like that.
As far as lens optics, we’re really splitting hairs here. 70mm through a quality lens in an imax theater is going to look absolutely fantastic and stunning. Digital is just more convenient and at some point it will catch up and surpass film.
My point was more like that even IMAX film doesn’t quite get to 18k equivalent, more like 12 to 16k. Honestly, anything above 4k (for normal widescreen content) even on big screens is barely noticeable if noticeable at all. THX recommends that the screen should cover 40° of your FOV; IMAX is what, 70°, so 8k for it is already good enough. Extra resolution is not useful if human eye can’t tell the difference; it just gets to the meaningless bragging rights territory like 192 kHz audio and DAC-s with 140 dB+ S/N ratio. Contrast, black levels, shadow details, color accuracy are IMO more important than raw resolution at which modern 8k cameras are good enough and 16k digital cameras will be more than plenty.
Resolution and color reproduction is still unmatched. Plus there are a lot of things happening in the analog domain that our eyes notice as beautiful.
Same thing is true for analog vs digital music production btw
I can’t speak for video, but for audio production that isn’t true. Audio signals can be perfectly reproduced, up to some frequency determined by the sample rate and up to some noise floor determined by the bit depth, digitally. Set that frequency well beyond that of human hearings and set that noise floor beyond what tape can do or what other factors determine, and you get perfect reproduction.
