Couldn't you make a film camera that was silent by rotating an array of lenses?

So instead of moving to the next frame, "stopping" the film for the exposure time, and then moving to the next frame. Instead move the film continuously and have a rotating array of lenses that follows the light to each frame without needing to stop the film on every time? Thereby making the camera near silent.

This is how some high-speed film cameras worked, using prisms or mirrors. You probably still need a shutter though

vad:
Even the slightest speed mismatch, jitter, film movement in a direction perpendicular to the plane of prism rotation, or lack of film flatness during motion would degrade image quality. Resolving all these mechanical issues is possible, but it would entail enormous complexity and cost, making it impractical for the mass consumer market.

I meant for like the film industry not for the consumer market. Since many people complain how imax cameras are so loud it's impossible to record any audio on set, seeing as those cameras are very expensive already it would seem logical to use something like this if it made them more silent.

vad:
Well, IMAX is focused on achieving the highest possible image quality. It's likely unfeasible to achieve the same level of quality using a continuously moving film without making the camera excessively large, heavy, expensive, or unreliable.
