Printer’s sync

EN: Printer’s sync

Cinematografie

This is the offsetting of sound 26 frames earlier than picture, corresponding to the distance between the sound reader and the gate of the projector. To be in sync on a projector all prints are lined up in printer’s sync. Usually the lab lines up the sound and picture in printer’s sync, putting the beep on the track 26 frames earlier than the 2 in the Academy Leader. This is known as pulling up the sound. If there was some reason for you to line up the sound yourself, it is very important to label the sync mark printer’s sync so that the sound is not accidentally pulled up twice.
