17 - EXTERNAL TIMECODE

EXTERNAL TIMECODE OFFSET

Before we look at the functions on this page, it must be said that some of the parameters
in this page are a bit specialised and apply only to certain applications. If you need these
specialised functions, you will know what you want. However, if all you need to do is set an
offset against incoming timecode, you can ignore much of this and skip straight to
SETTING TIMECODE OFFSETS on the next page.
Sometimes, it is necessary to set an offset between the DD1500 and the external
machine. For example, your project may start at 00:00:00:00 but the visuals start at
10:00:00:00. Using SHIFT+EXT. TIME (OFFSET), you may set offsets so that the two
machines play in sync without you having to extensively modify the project's start time.
You may also set offsets for the timecode displays on the DL1500 and external
monitoring as well as setting absolute and relative times. Pressing OFFSET gives this
screen:
The fields are:
ZERO IS AT
ABS(solute)
REL(ative)
NOTE 1: You may find it useful when starting a project from scratch to always start at, say,
1 hour and use the relative time display so that the project effectively still starts at zero. In
this way, if you suddenly find you need to add cues before 00:00:00:00, you can. If you
use absolute and start at zero, you will first have to slip all cues in the project forward to
accommodate the new cues.
NOTE 2: When using bi-phase, it is necessary to set the relative start of the film against
the audio on the DD1500. This is done by locating the film to the very first frame and then
locating the DD1500 to the start of the audio and pressing RESET ZERO. Please see the
section SYSTEM - TIMECODE GENERATOR for details on this.

This sets a relative offset and allows the 00:00:00:00.0
reference time to be placed at a time other than absolute
zero. For example:
0
16
ZERO IS AT : + 08:00:00:00.0
A DD1500 project can be likened to a 24 hour reel of tape
and, using the REL(ative) setting, you can play across
'midnight'.
The soft keys F1/F2 (ABS/REL) switch between absolute
and relative time display.
ZERO (F3/F4) sets the current time as the ZERO point.
This also has the effect of automatically switching ZERO IS
AT (i.e. the REL) time display to ON. You may select
ABS(olute) or REL(ative) more conveniently using the soft
keys F1 or F2 (ABS or REL) if you wish. You will note that
as you switch the ZERO IS AT field on or off the ABS/REL
keys highlight to indicate selection.
