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 typically 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.
Insert a Keyframe 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 operation when you insert on the path.
New Keyframe Inserted on the 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.
Build an Effect By Inserting a Keyframe on the Path
You can build an entire effect by inserting every keyframe on the path in the Master E-MEM
Module. Keyframe durations will be automatically calculated by the system. This can be
useful if you need to build an effect to match some pre-recorded material.
1 Review the recorded material and determine the times that keyframes are needed. In
this example, keyframes are needed at 1.5 seconds, 2.5 seconds, and 3 seconds.
