    Important note : you don't shoot 70mm, no films are shot with it, only 65mm.
    70mm is reserved for film projectors, all cameras use 65mm film, with an aspect ratio of 2,26:1, which is then converted (and slighty crop on the sides) to 2,2:1 on a bit smaller frame size to 70mm print.
    IMAX is also 65mm, but with an horizontal pull down, (much like Vistavision or Technirama), resulting in an absolutely enormous 15 perf 1,43:1 negative frame.
    (which is basically medium format size, just between 6x6 and 6x7)
    Only a handful of IMAX 15 perf projectors still remain in the world, and project it to its native format.

      Except in Russia, where camera negatives and intermediates are also 70 mm. Also, the Fox Grandeur process used for a couple of years from about 1929 was also all 70 mm, but the frame size and perforations were quite different to the Todd-so standard.

    In my country like in the rest of the world 35 mm films were the standard, as a filmmamker I have a crush with the old school film technique and since the first time I saw The hateful eight movie in the "glorious" 70mm my dream is shoot some day in this format, I know the huge price and technicals limitations that I will find but I hope achieve it.
    Pd: The Oppenheimer film put this topic in trends recently again.

    I saw the doors back in 1991 where val Kilmer plays rock legend jim Morrison. It looked amazing in 70mm. It was a 35mm film blown up to 70mm it was awesome seeing how big that screen was. I would love to see more movies in 70mm.

      There definitely aren't enough movies released in 70mm anymore, but it's a real treat when one does get released.

      One reason why 70mm blowups from 35mm negatives exist is to take advantage of the 6-channel magnetic soundtracks on 70mm which were usually much higher quality that what 35mm could offer. Ofcourse it all became moot when digital arrived and nowadays we even have object based audio. However, in the early nineties when The Doors was released, getting THAT soundtrack onto 70mm would have been a no-brainer.

    This was a great video, very accurate! I will say that 70mm blowups are also fantastic because 70mm film can be a lot brighter than 35mm film, as there is more light hitting the wider aperture plate and film area! Still can be a lot brighter than a lot of digital projectors when they have the correct arc lamp! Best of luck with the videos.

    • @CallumVandenberg

      Thanks! Glad you enjoyed the video. That's an interesting fact about 70mm being a brighter image.

    My favorite 70mm format is 65/15, otherwise known as IMAX. The negative is HUGE! I bought a frame (or cell) of Interstellar, and it dwarfs my 35mm still negs. Amazing.

      I work as a projectionist in a cinema and we used to have a strip of IMAX film. But we switched to digital years ago and some @ssh*le threw it away! Still get pissed when i think about it.

    So you are saying these original 70mm films are down sampled to 4k for Blu-ray releases

    • @CallumVandenberg
      @CallumVandenberg  20 днів тому

      Only in theory, as film does not have an actual resolution.

    They should scan old 70 mm movies in 4K & 8K. So is available on the streaming service, for example Netflix & UA-cam movies.

    • @BlaBla-jj6sh
      @BlaBla-jj6sh 5 місяців тому

      That already happens. Lawrence of Arabia and 2001: A Space Odyssey for instance both were scanned in 8K and released on UHD Bluray in 4K. Patiently waiting for the underrated Ryan's Daughter and Grand Prix to get the same treatment. Ice Station Zebra and especially It's A Mad Mad Mad Mad World would also be great candidates.

    The only 70 mm analog film i see was with Imax 3D of jean jacques Annaud movie wings of courage, i also see Michael Jackson Captain EO the same way in the mid 90s it was top notch and only avaible a Disneyland or Parc du Futuroscope, today it's very rare in Europe and almost disapeared in France, in the past we have some huge screen in Paris , now there was only two theatre that show Oppenheimer in true 70mm as a limited roadshow.

    • @CallumVandenberg

      That's very surprising considering how popular the cinema is in France.

      @@CallumVandenberg production of movied goes full digital now , it's rare for French director to have the budget to shoot in analog format, Éclair analog lab was close , it's now a cinémathèque kind of movie museum, they probably goes in London for chemicly process the ECN-2 negative , in US and Canada they still have lab and budget to keep analog film alive.

    Wait a minute, 35mm film had 4 channel soundtracks begging with the robe.

    • @CallumVandenberg
      @CallumVandenberg  Рік тому

      True, CinemaScope productions used 4 channels of sound. However, only a few theatres could use the four channels. The majority of 35mm film productions continued to use 1 mono channel.

    You're so good it's a shame you don't have a lot of subs, but I'm sure it's just a question of time.

  • @smartrain1
    @smartrain1 Рік тому

    Sorry but I had to stop at 1.00. You made a huge error relating to the sound track/ picture area positioning. 70mm is well known not just for the picture quality but the 6 track magnetic sound (pre digital days). In post digital days the TODD-AO form remained, even though the mag tracks were replaced with a DTS time code.

      Thanks. Ya, I wish I could say it was how we pronounced it around these parts. But the reality is that I completely mispronounced it and didn't catch it until after uploading. Oh, well!
