In keyframe editing, there are two duration modes; switch between them in the 
keyframe operation section. (See “Time Settings” in Chapter 13 (Volume 2).)
Variable duration mode: In this mode, inserting or deleting a keyframe 

increases or reduces the duration.

Constant duration mode: In this mode, inserting or deleting a keyframe does 

not change the duration. This is useful for keyframe editing of an effect 
with a fixed duration.

In the variable and constant duration modes, the keyframes to which a modify 
operation applies, and the effect of a paste operation are different.

a) A new keyframe is inserted at the effect position.

Variable duration mode: The copied keyframe is inserted at the specified 

position.

Constant duration mode: The copied keyframe is written over the specified 

position.

You can determine the execution time of an effect by setting either the 
keyframe durations or the effect duration.
Keyframe duration: This is the time from the keyframe to the next keyframe. 

You can set this time in the keyframe control block. (See “Time Settings” 
in Chapter 13 (Volume 2).)
In constant duration mode (see page 110), it is not possible to change the 
keyframe duration setting.

Effect duration: This is the total execution time of the effect, from the first 

keyframe to the last. You can set this time in the keyframe control block.
(See “Time Settings” in Chapter 13 (Volume 2).)
