5 Render the composition into a movie again, using the same filename as the previous version of the movie.

To precompose layers
Precomposing is an easy way to nest layers within an existing composition. Precomposing moves the layers to a new
composition. This new composition takes the place of the selected layers—something that does not occur in
ordinary nesting. When you want to change the order in which layer components are rendered, precomposing is a
quick way to create intermediate levels of nesting in an existing hierarchy.
Precomposing also places the new composition in the Project panel, available for use in any composition.
1 In the Timeline panel containing the layers you want to precompose, select the layers.
2 Choose Layer > Pre-compose.
3 Select Leave All Attributes In or Move All Attributes Into The New Composition, and then click OK.
Leave All Attributes In Leaves the selected layer properties and keyframes in the original composition. The frame
size of the new composition is the same as that of the selected layer. Select this option when you do not need to
change the rendering order, such as when you precompose layers only to simplify or reuse a composition, not to
change the rendering order of layer properties. This option is not available when you select more than one layer or
atextlayer.Whenyouusethisoption,changesyouappliedtothepropertiesoftheoriginallayerarestillappliedto
that layer in the original composition.
Move All Attributes Into The New Composition Moves the properties and keyframes of one or more selected layers
one level further from the main composition in the composition hierarchy. The frame size of the new composition
is the same as that of the original composition. Choose this option when you want to change the rendering order in
the selected layers, such as when you want to rotate a layer but not its drop shadow.
