the phosphors on a monitor designed for 60+Hz are designed to degrade quickly, at 24Hz they'll be off ~1/2 of the time
Remember that when film plays back the projector shows you the same image for most of the 1/24 of the time before switching to the next frame
- sokoloff 6y agoRandom trivia: many of the old film cinema projectors are running with a flicker rate of 48Hz (showing each frame twice) or 72Hz (showing each frame three times). https://en.wikipedia.org/wiki/Movie_projector#Shutter https://en.wikipedia.org/wiki/Movie_projector#Shutter
- kalleboo 6y agoFilm projectors also actually show the same frame 2-3 times in a row to reduce percepted flicker (effectively giving you 48 or 72 Hz)
- jayd16 6y agoPAL TVs ran at 25hz. They most likely could find a monitor that would have looked fine. Its hard to say what they actually did just from what you see in the film. Filming monitors and TVs was and is a very common thing. You can probably get away with filming a 30 fps monitor if your shutter speed is tight enough and you're ok with a few pulldown frames sneaking in. >Remember that when film plays back the projector shows you the same image for most of the 1/24 of the time before switching to the next frame Is this true? Isn't it 50/50 or so? Take a look at a rotary disk shutter. Film is pretty delicate and you can't pull it through that fast.
- Taniwha 6y agoTVs use different, slower, phospors than computer monitors, they also scan alternate (50 or 60Hz) fields within a frame to help with the illusion
