This is actual IMAX film 🎞️ #oppenheimer #imax #imaxexplained #film

Watching imax on its actual film is breathe taking

[Rizky-Gumilar]

Nolan truly is the pioneer of IMAX for commercial blockbuster films. After the success of The Dark Knight many other directors started to use IMAX for their movies

[sebastianluu]

This is by far the coolest thing i've seen all day

[MrDjambronk]

I didn't know that audio can be printed on film!

[jasper]

Bit of trivia: The Star Wars/Empire films shown were most likely from trailers and not release prints because they were spherical and not anamorphic to be shown before spherical movies. Possibly for the 1997 re-releases since they have digital soundtracks along the edge.

shorts really give me some cool trivia once in a while

I love how IMAX frames are so large, they decided to build the filmstock to be run sideways rather than vertically to reduce its width. You can see from the way the perforations are across the top and bottom of the frame rather than down the sides.

[luckykennedy]

Those Star Wars prints are most definitely from the 97 special edition. You can tell because on the left there's this barcode looking thing which from what I've heard was used for the 5.1 mixes.

[Jomster]

Geesh louise, I never knew IMAX film rolls were THAT big.

This is freaking awesome. My local theater will be playing Joker 2 on IMAX 70MM and im so ready for the preorder tickets. Cant wait!!

[Artfulscience]

Can’t wait for BMD’s new 17k Ursa with a massive IMAX-like sensor

[HarshuiizZz]

Interstellar Oppenheimer God level from CHRISTOPHER NOLAN

[GracedSeeker]

I always wondered how they did the sound on film, cool

[Art-is-craft]

VistaVision turns 35mm on its side like IMAX 70mm and it produces a stunning picture.

[RichardFoster]

I could be wrong, but it looked like that 35mm film had both the analog (Dolby SR?) waveforms, which you mentioned, and the Dolby Digital equivalent (between the sprocket holes on the same side).

[tyjuarez]

On the 35mm strip (which looks to be a Star Wars 1997 Special Edition trailer) you can see four different audio formats.

1. Analog Stereo - the waveform next to the picture, read optically. More light = more voltage = more sound.
2. Dolby Digital - those itty-bitty QR-code lookin' things between the perforations. They even have Dolby logos in the center!
3. SDDS - Sony's competitor to Dolby, in blue on the outsides of the strip.
4. DTS - ok, the audio itself isn't there, that's on a CD-ROM that comes with the film, but the timecode that keeps the film and CD in sync is there, those little dots and dashes right next to the picture.

[KingRCT]

On the 35mm you can indeed see the audio waves on the left, but also 2D barcodes inbetween the holes (iirc that's the Dolby Digital audio. It looks like QR codes), and the whole blue line on the far left is also a uninterrupted 2D barcode (that one for SONY I think).

[deitay]

How doesn’t this have more views!

I never realized how film could be so different

[xxafthabxx]

No one's gonna talk about the background music? 😆

[jakeiiix]

Just saw interstellar in imax, incredible
