      what I feel like when I accidentally walk in the room

    2. Can anyone explain the why? What are all those different lengths and turns and rollers or whatever doing?

      Why does it have to go be draped all around the room and go through some dipsy doodles before and after going to the projector?

      That’s 15/70mm film
      It retains significantly more detail and resolution than standard film or even most digital formats.

      At first I thought the operator was walking in with a battle shield 🛡️ 😂

      That appears a little more complicated than my original Eumig Standard 8mm projector.

    7. are all the long stretches to dissipate heat? It seems horribly inefficient, but there has to be a reason

      Thank goodness it’s not a short film, because there wouldn’t be enough film to thread the projector!

    9. “Can’t we make the reel go from point A to point B?”

      “Well, yeah. But then, we wouldn’t need a specialist.”

    10. IMAX uses 15/70mm film—three times taller than standard 70mm—which weighs over 500 lbs per reel and runs at 5.6 feet per second, creating immense momentum and tension risks. A simple straight feed would cause film tearing, jamming, or projector damage from any minor fluctuation in speed or slack.

    11. Here’s a comment by u/Rampage_Rick from a year ago:

      >>> The main reason for all those extra rollers is to manage the slack between the storage platters and the projector. The extra loops act as a cushion.

      > For 70mm IMAX the film alone weights 500+ lbs and moves at 5.6 feet per second, so there’s a lot of momentum on those platters. If it came straight off and fed into the projector, any tiny hiccup could tear the film or damage the projector.
      >
      > Secondary to the slack, those platter racks (“Quick Turn Reel Unit”) can hold 4-5 platters, with the film spooling off of any one level and back onto any other level. Thus a few of those rollers are just to get the film alignment off and on to the correct levels.
      >
      > Thirdly, the green rollers near the back of the projector are sticky, and are meant to clean off any dust that’s on the film.
      >
      > Fun facts about the QTRU: They are operated via a Palm Pilot (or an emulated Palm Pilot on an iPad) and they use light bulbs from Mercedes

    12. Makes me realize how little I know about film. I recently said I wouldn’t go back to a theatre until I could watch in something more than 240p but if they’re still loading up old reels like this on an obsolete platform then it’s understandable why it looks as bad as it does ig.

      This is why I love Tiktok. There’s always something niche or cool that someone does and you never thought or seen it before. I learned a lot of shit there too.

      Can anyone ELI5 why real film is used and not just digital? Probably must be picture quality, but how come picture quality is so much better with film or worse digital?

    15. Well, this sure is fascinating to see, especially considering how excessively digital things are nowadays… but why is it so complicated? Doesn’t putting the film through this amount of rollers and loops and whatever cause accelerated wear and tear?

      IMAX projectionist is probably my favourite job that I have ever had.

      I love 70mm.

    17. Help me understand… Why does it have to go through so many loops and gears? Doesn’t it increase the risk of tangling or breaking? I’m sure there’s a reason and a purpose.
