How a Film Camera works in Slow Motion - The Slow Mo Guys
Merch! -
Gav shows the impressive internals of an old 16mm motion picture camera by filming it in some lovely crisp 4K slow motion at 1000fps. Lights! Camera!......... well that's it, really.

    Hi guys, what do you think about a tribute to Michelangelo Antonioni''s Zabriskie Point? Should be interesting to record the slow motion explosions of the same / similar objetcs that the he flmed in 1970. What do you think about?

    Here's an idea that will get zero views in the USA, a cricket ball on bat in slow mo. I'd also love to see a spinners ball hitting the ground and moving sideways.

    You guys should make a plane turbine slow mo video!

    You should record something with the 1000 FPS film camera and compare with the phantom

  • ZTenski

    If you're looking for video ideas, the inside of a DLP projector is pretty unreal and might make a nice cheap project, assuming you have macro lenses. It's got millions of tiny mirrors on a 2 inch surface that all move up to dozens of times per frame to make the color pixels. I'd be interested in seeing it in slow mo. There's one guy who's done it with strobe lights but I'd be curious to see it in fluid motion.

    You guys should do a video of shooting or blowing up a propane tank. I think it would be a cool yet experimental video will for example when it blows up with the propane ignite or will the gases just escape into the air

    Hi Gav, great episode with some unique detail, cheers. i was wondering if you had ever thought of doing the following slow motion... 1. a bird of prey 2. a greyhound race(take-off, mid-race, etc) 3. the sonic boom of a fighter jet breaking the sound barrier(i'm sure Dan could help arrange this one)

    I've been an analogue motion film camera technician for over 35 years now and this is by far the best explanation of how an analogue motion picture camera works. My hats off to Gav in not only his spot-on understanding of the machanics of it all but for so perfectly using his digital and optical tools and skills to capture, edit and deliver that explanation!

      I actually did shoot an outro on the film camera but the covid processing times would have delayed this video by weeks. Thinking about doing it with the high speed film camera. Shooting the whole thing on film.
