6. The effect now runs backwards, starting at keyframe #2, and
ending with keyframe #1.
NOTE: If the Enable source (for example, M/E 1) has been de-selected,
it will appear as if the effect has been erased. Simply re-select the Enable
button, and the effect will be “restored.”
Advanced Keyframe Editing
This subsection introduces more complex and advanced keyframe
editing techniques. You will be setting Enables and Delegates
(refer to Appendix B,
Keyframe Facts ) and manipulating
timelines.
■ Make changes to the keyframe: MOD – absolute or relative;
single or multiple keyframes.
■ Keyframe Timelines
■ Constant Duration Mode
■ Manipulating Entire Effects
Insert A Keyframe (when ‘on’ a keyframe)
Pressing Enable buttons (such as M/E 1, M/E 2, etc.) on the
E-MEM panel delegates individual register levels so that changes
can be made to those levels. While effect editing, you would
normally enable all levels that contribute to the overall effect.
When you want to make changes to individual levels, you should
delegate only those levels and perform the operation (Insert Before,
Insert After, Mod, Cut, Paste, etc.). Only the delegated levels will
be modified. Those levels which are enabled but not delegated
will not be modified.
