Using Property and Tracking Controls (PB only)
3 For Apply To, select the type of curve you want The Wiggler to change. If you selected
keyframes for a property that varies spatially, you can select Spatial Path to add deviations
to the motion, or Temporal Graph to add deviations to the velocity. If you selected
keyframes for a property that does not vary spatially, you can select only Temporal Graph.
4 Select a Noise Type option to specify the type of deviation due to randomly distributed
pixel values (noise):
• Smooth Noise produces deviations that occur more gradually, without sudden changes.
• Jagged Noise produces sudden changes.
5 Select the dimensions of the property you want to affect:
• One Dimension adds deviations to only one dimension of the selected property. Choose
the dimension from the menu.
• All Dimensions Independently adds a different set of deviations to each dimension.
• All Dimensions the Same adds the same set of deviations to all dimensions.
6 Set a Frequency to specify how many deviations (keyframes) per second After Effects
adds to the selected keyframes. A low value produces only occasional deviations, while a
high value produces more erratic effects. A value between 0 and 1 creates a keyframe at
intervals of less than one per second. For example, a value of 0.5 creates one keyframe
every 2 seconds.
7 Set a Magnitude to specify the maximum size of the deviations. After Effects sets the
specified magnitude to the units of the selected property, so a value for one property may
produce very different results in another property.
8 Click Apply and preview the results.
9 If necessary, choose Edit > Undo The Wiggler to reset the keyframes, adjust the values
for Frequency and Magnitude, and then reapply The Wiggler.
