Guide For A Seamless Change-Over
Occasionally, when running a DTS movie with dual projectors, you may come across situations when the picture
and sound are not changing in unison during a change over. This is due to the fact that as soon as the first frame
of action reaches the picture aperture on the incoming projector, the DTS digital sound will change over to that
reel. DTS digital sound changes independent of the projector’s dowser position. Change over anomalies are
most evident on movies that have very tight editing / scene change tolerances from one reel’s end to the next
reel’s start.
Since every brand of projector has variances (speed, for example), you may come across occasions when, during
a change-over, the picture and sound are not changing at the same time. When this occurs, do the steps below.
Sound changes before picture
When threading the incoming projector, roll down the film to a greater number of feet. If you normally thread to
“8", try threading to “9" or “10”. Keep adjusting the roll down setting until the picture changes with the sound.
Also, try hesitating a second before
starting the incoming
projector on the first cue.
Picture changes before sound
When threading the incoming projector, roll down the film to a lesser number of feet. If you normally thread to
“8", try threading to “7” or “6". Keep adjusting the roll down setting until the picture changes with the sound.
Be sure to hesitate opening the dowser on the incoming projector (on the second cue) until the last word on the
outgoing reel is heard on screen.
Determining roll-down
Adjusting the roll down setting is a judgment call. Base it on the time delay of picture vs. sound. One second of
delay equates to 24 frames, or 1
. 5 feet.
