Improving Performance with Filters
When applying filters to several different layers in Motion, it is recommended that you
apply the filters to the layers’ parent group. Also, when applying filters to very large
groups (such as a group containing a growing particle system), you should select the
Fixed Resolution checkbox in the Group tab of the Inspector. When Fixed Resolution is
selected, layers that are in the group but are outside of the Canvas are cropped to the
size of the group defined in the parameter. The Group tab is only available when a group
is selected. For more information, see
Fixing the Size of a Group .
Note: When enabled, the Fixed Resolution parameter crops the group to the size
specified in the Fixed Width and Fixed Height parameters around the anchor point of
the group.
Where Filters Appear
After you apply a filter, it appears underneath the object to which it is applied in the
Layers tab and the Timeline.
