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 

 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).

The path that an effect takes between keyframes may be adjusted 
through the 

 path type selection from the Keyframe Path 

Menu.

If 

 is selected, three soft knobs are provided to control the 

three parameters of the vector. These are labeled: Tension, 
Continuity, and Bias.

The adjustment of these controls can affect the keyframe path in 
various ways. Interactions between the controls are numerous 
and each will be described in the following paragraphs. You may 
want to experiment with the interactions by adjusting the controls 
in small increments.

In the following examples, a physical path is shown between three 
keyframes. The first keyframe (KF1) is the upper left square; the 
last keyframe (KF3) is the lower right square. The adjustments in 
these examples are applied to the middle keyframe only (KF2).
