After Effects can output several specialized formats, however you won't find them in the render queue. Instead, check File>Export for several specialized formats. Some options (like the FLV exporter) require you to have optional software installed. Here's a list of some that you may encounter:
Adobe Motion Exchange (.amx) for LM2 | Allows you to save data out for use in a LiveMotion project. LiveMotion is SWF authoring tool from Adobe that supports advanced animation. |
Macromedia Flash (SWF) | This will write a standard Macromedia SWF file in the Flash 5 format. |
AIFF | An audio only format used mostly by Macintosh machines |
AVI | A ˜well established windows video format |
DV Stream | A raw stream of Digital Video. |
Image Sequence | A series of still graphics for each frame of the comp. Useful for sending files when the output codec is questionable. |
Macromedia Flash Video (FLV) | If you have Flash MX 2004 Professional installed, you can write a compressed video format that works well for Flash authoring. |
MPEG-4 | A compressed file format for web delivery. It is usually better to render a QuickTime first, then compress |
QuickTime Movie | Use the Render Queue instead |
Wave | An audio only format used mostly by Windows machines |
¼ Law | An audio only format |
