Section 2— Control Panel Descriptions
The data entered into the keyframe on each delegated level is the
data in the Current Working Buffer, which is the same as the
Current Switcher State for that level. This includes the values of all
parameters at that point, interpolated on-the-path between the
two keyframes, plus any changes that may have been made on the
control panel and in the menus since stopping at that point on the
timeline.
The duration of the inserted keyframe is the difference between
the point of insertion and the position of the next keyframe. The
duration of the previous keyframe (what had been the current
keyframe) is decreased by the same amount. The current time
position remains at the point of the newly-inserted keyframe.
When the Time Cursor is positioned on a Master Timeline
keyframe, CUT deletes the keyframe from any delegated level that
has a keyframe, and deletes the duration of the Master Timeline
keyframe from all delegated levels, even those that do not have a
keyframe at that point. All subsequent keyframes are rippled
backward in time (toward Time 0) by an amount equal to the
duration on the Master Timeline of the deleted keyframe. This
decreases the overall duration of the effect by the duration of the
cut keyframe.
When the Time Cursor is not on a Master Timeline keyframe, the
CUT
button is disabled and the Cut operation is not permitted.
COPY makes a copy of the data in the Current Working Buffer, for
all delegated levels, and places it in the Clipboard Buffer. No
changes are made to the effect.
If the Time Cursor is on a keyframe on the Master Timeline when
the Copy is done, the duration of the copied keyframe is the
duration of the Master Timeline keyframe. If the current time
position is on-the-path on the Master Timeline, the keyframe
duration is the difference between the current time position and
the position of the next keyframe.
The keyframe can then be pasted into another effect (same levels)
or into another point in the same effect (same levels).
