E-MEM & Timeline Operation
based on an existing keyframe, with some modifications. For Insert After
keyframe 2, the starting point for the inserted work buffer data will be key-
frame 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. 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 opera-
tion when you insert on the path.
Figure 110. Insert on Path
Note that after inserting on the path, the preceding keyframe’s duration is
shortened and the new keyframe’s duration extends to the next keyframe.
When keyframes are inserted on the path the overall effect duration does
not change.
When an empty register is recalled, no keyframes exist yet for the cursor to
be on or between. In this situation, because the cursor is not on a keyframe
the Insert operation inserts on the path. This is why either Insert button can
be pressed to create the first keyframe in a new effect.
Building an Effect By Inserting on the Path (in Master E-MEM Area)
You can build an entire effect by inserting every keyframe on the path in the
Master E-MEM area. Keyframe durations will be automatically calculated
