Create placeholders for output
You can create placeholder files that can be used in different compositions. For example, you can create a placeholder
for an item in the render queue that will create a 24-fps movie and then drag that placeholder into a 30-fps compo-
sition. 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.
❖
Drag the Output Module heading for a queued item from the Render Queue panel to the Project panel. After
Effects creates a placeholder for output in the Project panel and sets the Post-Render Action option for the item to
Import & Replace Usage.
Loop a footage item
If you intend to loop a visual footage item continuously in your project, you only need to create one cycle of the
footage item in After Effects.
1
In the Project panel, select the footage item to loop.
2
Choose File > Interpret Footage > Main.
3
Type an integer value for Loop and click OK.
Importing from After Effects and Adobe Premiere Pro
Import an After Effects project
You can import one After Effects project into another. Everything from the imported project, including footage
items, compositions, and folders, appears inside a new folder in the current Project panel.
You can import an After Effects project from a different operating system, as long as you maintain the file names,
folder names, and either full or relative paths (folder locations) for all files in the project. To maintain relative paths,
the source footage files must reside on the same volume as the project file. Use the File > Collect Files command to
gather copies of all files in a project or composition into a single location.
Note: When you render a movie and export it to the QuickTime (MOV) or Video for Windows (AVI) container format,
you can embed the After Effects project or a link to the project in the container file. To import the project, import the
MOV or AVI file, and choose Project from the Import As menu in the Import File dialog box. If the file contains a link
to a project that has been moved, you can browse to locate the project.
1
Choose File > Import > File.
2
Select the After Effects project to import, and click Open.
If a file format is not supported by the operating system that you are using, if the file is missing, or if the reference
link is broken, After Effects substitutes a placeholder item containing color bars. You can reconnect the placeholder
to the appropriate file by double-clicking the entry in the Project panel and navigating to the source file. In most
cases, you need to relink only one footage file. After Effects locates other missing items if they’re in the same location.
