This document lists the file formats which Adobe After Effects CS4 can import and export. Third-party plug-ins are available to extend these capabilities—see Obtain support for additional formats and codecs for more information.
Note: In order for After Effects to import a QuickTime or AVI file, the codec that a particular file uses must be installed on the computer. (Common codecs are installed by both QuickTime and Video For Windows.) If you receive an error message or the video does not display correctly, you may need to install the codec used by the file. For more information about the codec in use, contact the manufacturer of the software or hardware used to create the file. You can read more about codecs and digital video file formats in the Adobe video and audio primers.
Important: QuickTime is required to import and export some file formats on Windows. You can download the latest version of QuickTime from the Apple website.
Most file formats are rendered from After Effects by adding the composition to the render queue; see Render and export a movie using the render queue. Some formats are only available through the File > Export menu; see Render and export a movie using QuickTime components.
