The article implies that an intermittent mechanism is not used in a camera for some reason to do with the shutter. This is wrong, of course - in a typical camera the film still must be stationary during exposure. The only exception would be in a camera that uses a rotating prism - typically only a very high speed camera. I'm too tired to edit now, but will check back. --JSR

Definition[edit]

"The intermittent mechanism or intermittent movement is the device by which film is regularly advanced and then held in place for a brief duration of time in a movie camera or movie projector."

Methods used[edit]

There's a section in parenthesis that makes little sense to me and breaks up the flow of the text:

"the standard for regular motion in North America is 1/48 of a second, which corresponds to 180 degrees, but shutters with 200 degrees were popular back when the then-available color negative film had an ASA of 50; today's color negative film is available with an ASA of 500"

It seems to only apply to North America, is unsourced and vague on dates and definitions. I'll move it to the end of the section and let someone who understands these things better either expand or remove it — Preceding unsigned comment added by 212.139.13.2 (talk) 12:27, 1 October 2021 (UTC)[reply]
