Workprint

Frame captured from a digital editing workprint. The timecode on the left begins with a userbit designating the lab roll and the code on the right is a Keykode.

A workprint is a rough version of a motion picture or television program, used by the film editors during the editing process. Such copies generally contain original recorded sound that will later be re-dubbed, stock footage as placeholders for missing shots or special effects, and animation tests for in-production animated shots or sequences.
