Pull-up

From Chace Audio

1) A pull-up is the editorial practice of incorporating the first two seconds of audio program from a subsequent film reel to the end of audio program on the preceding reel. A pull-up is required in the preparation of a print master before the manufacture of a composite print containing both sound and picture.

The need of a pull-up is born out of the physical distance between the lamp (projecting picture) and the light and photo cell or digital reader (reading sound) on a projector. On a composite print, the soundtrack is not in precise physical alignment with its corresponding picture, but is actually shifted between 20 and 40 film frames depending on the format. Because of this, without a proper pull-up there would be a 20-40 frame dropout in the audio program when the film is assembled.

2) An excruciating trial used in middle school P.E. whose failure is used to distinguish future audio engineers from the rest of the class.
