Section 5 — System Operation

Inserting on a Keyframe With Insert Before

When the edit cursor is on a keyframe, pressing

Insert Before

inserts a new

keyframe at that timeline 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 384

). Note that keyframes are renumbered after the

insert. In the example, what was keyframe #1 becomes keyframe #2
(

Figure 270

).

Figure 270. Insert Before

Using Insert After or Insert Before on a Keyframe

In an existing effect, an Insert After at the keyframe 2 location would seem
to be the same as an Insert Before at the keyframe 3 location, but this is
usually not true. The work buffer material inserted into an effect is typi-
cally based on an existing keyframe, with some modifications. For Insert
After keyframe 2, the starting point for the inserted work buffer data will
be keyframe 2 values. For Insert Before keyframe 3, however, the inserted
material will be based on keyframe 3 values. If the starting parameters in
keyframe 2 and 3 are different from one another, the look of the resulting
effect will vary depending on which Insert operation is performed.

Inserting on the Path

When the edit cursor is not positioned on a keyframe, the insert operation
inserts a new keyframe at the current location. This is called inserting on the
path (

Figure 271 on page 383

). The default duration of new keyframe

inserted on the path will be the time between the cursor location and the
next keyframe on the Master Timeline. The

Insert After

and

Insert Before

buttons perform the same operation when you insert on the path.
