The following options indicate the particular point on the pivot frame that remains
constant throughout the footage. Place the effect points to select an area for stabilization.
If you select multiple points, consider that Color Stabilizer is most effective when those
points vary widely in color or brightness.
Black Point Specifies a single point that will remain constant, if you choose to stabilize
brightness only. If you choose to stabilize levels or curves, this specifies a dark point that
remains constant.
Mid Point Specifies a point between two values of color or brightness that will remain
constant. This option is available only if you choose to stabilize curves.
White Point Specifies a light point that will remain constant. This option is available only
if you choose to stabilize levels or curves.
Sample Size Specifies the size, in radius of pixels, of the sampled area.
Filling all masks in a layer
The Fill effect now includes an All Masks option that fills all the layer's closed mask paths
with the chosen color. Activating this option also fills the mask path of a mask that has
None chosen as its mode. Choose Effect > Render > Fill to access the effect. To fill each
layer mask, make sure that the All Masks option box is checked in the Effect Controls
window.
Fill All Masks behavior when Add is chosen as the mask mode (top) and when None is chosen as the
mask
mode (bottom)
Constraining scale in the Transform effect
You can now scale both the width and height of an image with a single control in the
Transform effect. To to do this, make sure that the Uniform Scale box is checked in the
Transform Effect Controls window, and then scale the footage.
