  1. Video camera? It's a movie projector. by NixieBunny · · Score: 5, Informative

    There is a difference between movies and videos, and between projectors and cameras. Subtle, but it's there.

    1. Re:Video camera? It's a movie projector. by Bing+Tsher+E · · Score: 4, Informative

      A Kodak Brownie is a regular 8mm camera. Not Super 8. Super 8 uses a film cassette, whereas regular 8mm used 16mm film with a sprocket on both sides. You turned the reel over to shoot the second side, then at the processor they split the film in half. For inexplicable reasons, Super 8 and Regular 8 film had different sprocket hole sizes, so they are incompatible formats.

      Because Regular 8 film was regular 16mm stock and rolled on an open generic film reel, you can probably still get it. Super 8? Probably not.

  2. It's the film handling.... by meekg · · Score: 4, Informative

    The important part is the film handler. Unlike a camera, which can run the film more or less continuously and use a fast shutter speed, a projector has to stop the film for most of the frame's duration, and then quickly accelerate it out of the way while only blocking the light for a very short duration, or else the movie would "smear". Of course it flickers, since this is Lego, but it doesn't smear, and that's quite a feat.
