Closed captioning – Adobe Premiere Pro CC v.7.xx User Manual
Page 31
Note:
Show duplicate frame markers
Premiere Pro assigns a color automatically to each master clip that has a duplicate clip. Up to ten different colors are assigned. After ten colors are
used, the tenth color is reused.
For example, say, you've used multiple cameras to shoot a sporting event. You may use different shots of the crowd all through the show. If you
use the same crowd shot more than once, then duplicate frame detection alerts you to the duplicate clip by displaying a colored stripe across it.
Duplicate frame markers are not available for still images and time remapping.
