Film leader

"Film leader", used generically, refers to different types manufactured for many editorial and laboratory uses.

"Painted leader" is perforated film in overall colors, usually white, black, red, blue, or green.

Head leaders are marked with visual and audio information that may be used to ensure that the correct amount of time is allowed for the machine to run up to speed and arrive at the beginning of the program or movie.

The countdown section begins with a single frame bearing the words "Picture Start."

Unlike the previous film standards, no provision is made for changeover cue marks because digital cinema files are continuous.
