When Track View is open, the L ens Effects filters

left side of the Track View interface. Under each
filter are the parameters which can be animated.
These are displayed individually. You can animate
only the parameters you need to.
When viewing Gradients in Track View, notice
that the first two flags have only a color track
associated with them. This is because they are
the start and end points of the gradient and never
move. Any flags created after the first two will also
have a position track asso ciated with them. This
meansthatyoucananimatenotonlythecolorof
any flag in any gradient, but also its position over
time as well.
If you disable the animation capabilities for a
particular lens flare parameter, the corresponding
entry in Track View immediately disappears. For
