→Jitter: Added noet about jitter due to wear being audible while printed-in jitter is not. Clarified that jitter caused by "improper" gate tension is caused by gate tension that is too low.

Vertical unsteadiness. Common causes include | Vertical unsteadiness. Common causes include [[gate tension]] that is too low, mechanical wear of the intermittent movement, excessively oily or dirty film, or preexisting perforation damage. | ||
Jitter is often printed in - this can be especially evident on subtitled films with [[laser subtitles]], where the subtitles will appear perfectly steady on screen but the image will still move. Printed in jitter is often more of a gentle bounce than a shaking movement and is commonly caused by high speed release printing, which was especially popular in the mid 90s - 2000's to satisfy high print runs with tight turnaround times. | Jitter is often printed in - this can be especially evident on subtitled films with [[laser subtitles]], where the subtitles will appear perfectly steady on screen but the image will still move.

Jitter can be especially noticeable if frame lines are visible on screen due to overcut aperture plates or lack of masking, which will direct the audience's gaze to a jittering straight frameline. | Jitter can be especially noticeable if frame lines are visible on screen due to overcut aperture plates or lack of masking, which will direct the audience's gaze to a jittering straight frameline. | ||
Jitter caused by splices, damage, or low gate tension will cause chattering in the gate, while printed-in jitter will be silent. | |||
