176 KAYENNE — User Manual
Section 3 — System Operation
Inserting a Keyframe
The Insert Before and Insert After operations are used to insert new key-
frames onto the timeline of an effect. The result of the Insert operation
varies depending on whether the edit cursor is on a keyframe or between
keyframes (on the path).
An inserted keyframe has both work buffer values and a duration. The key-
frame duration is calculated by the Kayenne system (time to the next key-
frame) and is not actually contained in the keyframe data. This permits
added flexibility during effect editing.
Inserting on a Keyframe With Insert After
When the edit cursor is on a keyframe, pressing Insert After inserts a new
keyframe after the current one. The insert occurs after the duration of the
keyframe the cursor is on, at the next numbered Master Timeline keyframe
location. This inserted keyframe’s duration is, by default, the duration of
the keyframe the cursor was positioned on before the insert, though this
value can be changed by the operator (see
page 180). The edit cursor also
moves to the start of the new keyframe. This operation will increase the
duration of the effect by the duration of the inserted keyframe. (
Figure 118).
Figure 118. Insert Before
Inserting on a Keyframe With Insert Before
When the edit cursor is on a keyframe, pressing Insert Before inserts a new
keyframe at that time line location. The old keyframe, and all the keyframes
that follow, are moved to the right the length of the new keyframe’s dura
-
tion. This operation will increase the duration of the effect by the duration
of the inserted keyframe, which by default is the duration of the keyframe
the cursor was originally positioned on before the insert, though this can be
changed (see
page 180). Note that keyframes are renumbered after the
insert. In the example, what was keyframe #1 becomes keyframe #2
(
Figure 119).
