Fill Features

To understand the utility of System 5's Fill features, consider the following situation:
In a new mix, fader automation is recorded from 00:01:00:00 to 00:02:00:00
and from 00:04:00:00 to 00:05:00:00. What initial fader value is used if re-
cording or playback begins at 00:03:00:00?
Because there is no automation written at this time, it is called virgin territory. System 5
uses two methods to derive a value for the fader:
• First, it looks back from the current position to the beginning of the mix for the
last value recorded. In the example above, it would use the last fader value at
the punch-out point (00:02:00:00).
• If no valid value is found, it looks forward for the nearest valid value from the
current position to the end of the mix.
This method makes it unnecessary to do a complete initial pass just to write a setting
throughout the mix; the engineer can record moves only where they are needed.
It is sometimes desirable, though, to write nominal values in all, or selected areas of the
mix and System 5 provides utilities to accomplish this: AutoFill, Fill Start, Fill End,
Fill Region, and Fill to Punch.
14.8.1

AutoFill

AutoFill writes the value at the punch-in point back to the beginning of the mix (or
previous punch-out point) and to the end of the mix (or next punch-in point). AutoFill
can only be used during a parameter's first automation pass, which ends when the tape
stops; more than one punch in/out is permitted. If automation has already been recorded
for that parameter, AutoFill can be set to On but will have no effect. AutoFill acts in-
dependently on Absolute and Trim automation but has only one setting.
Figure 14-9 shows the results of a first automation pass recording fader movements in
two discontinuous sections. Figure 14-10 (left) shows the resulting fader values with
AutoFill Off. The dotted lines indicate virgin territory and the level derived for the
fader if the tape were located there. Figure 14-10 (right) shows the resulting fader values
with AutoFill On. The flat solid lines, marked Filled, indicate where AutoFill wrote
values. Two or more discontinuous punch sections can be used during the first pass only
if the tape is not stopped before recording the additional punch in/out sections.
