Effect Editing
Effect editing involves changing work buffer values using panel and/or
menu controls, then applying these values to the effect. This discussion
concerns effect editing, using the Master Timeline for the examples.
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 Karrera 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 222 ). 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 108 ).
