Creating output chains

Use output chains to create files that can be used in different compositions. For example, you can create a placeholder for the rendered version of a 24-fps movie and then drag that placeholder into a 30-fps composition. Then, when you render the 30-fps composition, After Effects first renders the placeholder at 24 fps and uses this rendered version as it renders the 30-fps composition.

To create an output chain:

Drag the output module for a queued item from the Render Queue window to the Project window. After Effects creates a placeholder for output in the Project window and sets the Post-Render Action option for the item to Import & Replace Usage.
