Replacing and substituting footage
After Effects offers a number of ways to replace and substitute footage in a composition.
Using proxies or other items in place of original footage can be useful when the footage you
want to use is not available. Also, when you are working with large, high-resolution items,
you may want to use low-resolution proxies to work more quickly and efficiently.
Replacing footage throughout a project
You can replace one footage item with another at any time while working on a project.
This can be useful if you receive a new version of a source file used in your project, and you
want to replace the original footage with the new version. The new footage item replaces
the existing one in layers and compositions throughout the project. When you replace
footage, all values (property settings, effect settings, and so on) remain applied to the layer.
To replace footage throughout a project:
1 In the Project window, select the name of the footage item you want to replace.
2 To import a replacement file, choose File > Replace Footage > File, select the file, and
then click Open.
Note: If the new footage item is a different size, it is not scaled to fit the original item’s size.
Replacing footage of one or more layers
You can replace the original source footage of one or more layers without changing any
settings applied to the original footage. The new source footage or composition takes the
place of the old source to the layers, but uses the existing keyframes.
To replace the source footage of one or more layers:
1 In a Timeline window, select the layer or layers to be replaced.
2 Hold down Alt (Windows) or Option (Mac OS) as you drag a footage item or compo-
sition from the Project window to any of the following places containing the selected
layers: the Composition window, the Timeline window, or the Composition icon in the
Project window.
