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 of the layers while retaining all the properties from the old layer.

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 composition from the Project window to either of the following places containing the selected layers: the Composition window or the Timeline window.
3. Release the mouse and then the keyboard key.
