Appendix B — Keyframe Facts
When DELEGATES is selected, only specified enabled levels are
delegated; all other enabled levels are enabled but not delegated.
This feature allows you to edit a delegated timeline while viewing
its relationship to timelines not being edited. When a level is not
enabled, its timeline disappears, and its keyframes are removed
from the master timeline.
With DELEGATES on, the timelines of all enabled levels remain
displayed in the Timeline menu and the Enable buttons of the
undelegated levels go to low tally. Pressing individual Enable
buttons on the E-MEM panel then delegates individual register
levels so that changes can be made to those levels. The buttons of
the delegated levels go to high tally and the names of those levels
are highlighted in the Timeline menu.
During effect editing, you would normally enable all levels that
contribute to the overall effect.
When you want to make changes to individual levels, you would
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.
It is recommended that you do selective insertions of keyframes
by using the
DELEGATES function. That is, that you only insert a
keyframe on a level if it has value. Extra keyframes get in the way
when it comes time to modify portions of the effect, especially if
keyframes are moved in time. In addition, using unnecessary
keyframes quickly deplete the keyframe pool (see the main E-
MEM menu for the number of available keyframes).
