IMAX cameras produce loud mechanical noise during film capture operations
Modern IMAX film cameras generate significant operational noise due to their large format and vacuum systems required to hold the film flat.
Film transport creates constant sound
An IMAX camera moves a huge amount of film through its mechanism. The enormous strip races through the device while each frame is exposed. This process requires a vacuum system that adds to the overall noise level.
Standard cycle repeats frequently
A standard cinematic film camera advances the film and repeats the exposure cycle 24 times every second. An IMAX format uses 15 perforations per frame on a 70mm projection print. The larger number of sprocket holes means more film must be moved during each shot.
