Keyframes
Duration modes
In keyframe editing, there are two duration modes; switch between them in the
keyframe operation section. (See “Creating and Editing Keyframes” (page
709).)
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.
Difference in keyframes to which a modify operation applies
a) A new keyframe is inserted at the effect position.
Difference in the effect of a paste operation
Variable duration mode: The copied keyframe is inserted at the specified
position.
Constant duration mode: The copied keyframe is written over the specified
position.
Transition mode
You can use an effect created with keyframes as a DME wipe pattern on the
switcher. In this case, it is necessary to set the transition mode (the way in
which the effect behaves).
For details of the setting, see “Transition Mode Settings for User
Programmable DME” (page 721).
Time Settings
Keyframe duration and effect duration
You can determine the execution time of an effect by setting either the
keyframe durations or the effect duration.
