changeover cue

The second mark, known as the changeover cue, is placed about 1 second before the end.

Seven seconds later the end of the leader and start of program material on the new reel should just reach the gate of the projector when the changeover cue is seen.

Film prints could be prepped by a projectionist with automatic changeover cues, which were small metallic appliqués which could be applied to a print at the first cue mark.

After another ten and a half feet (3.2 m) of film is shown (seven seconds at 24 frames/sec), the changeover cue should appear, which signals the projectionist to actually make the changeover.

Conventional release prints, which are made from timed internegatives, usually contain black motor and changeover cue marks as the printing internegatives are "punched" and "inked" for this specific purpose.

If the print is to be shown on a two-projector system, ensuring that the leaders and tails of each reel are spliced to the picture footage correctly and that the visual changeover cues are present.

A cue mark, also known as a cue dot, a changeover cue or simply a cue is a visual indicator used with motion picture film prints, usually placed on the right-hand upper corner of a frame of the film.

EKs, being made from the composited camera negatives, which are never "punched" nor "inked", have white motor and changeover cue marks as these marks are punched (or are scribed) directly on the prints, by hand, in the lab.

The second mark (changeover cue) would alert the projectionist that the changeover was imminent, and one full second after the mark he would trigger a solenoid that would open the incoming projector and another solenoid that would close the outgoing projector.
