Output Type Considerations; Film Or Videotape - Adobe AFTER EFFECTS 7.0 Manual

Render settings, such as frame rate, resolution, and quality, determine how After Effects processes your composition
during rendering. Output settings, such as format and video and audio settings, determine how After Effects saves
your rendered file. When choosing an output module, click the module name to customize settings in the Output
Module Settings dialog box.
In Mac OS and in Windows with QuickTime installed, you can render QuickTime formats through the Render
Queue panel. However, some QuickTime options, such as Fast Start and Hinted Streaming, are available only
through the QuickTime exporter (choose File > Export). For more information, see "Exporting using QuickTime" on
page 622.
You can create templates that contain commonly used render or output module settings.

Performance considerations
If you work with large compositions, make sure that you configure After Effects settings to improve performance.
Lowering the bit depth of a project, substituting proxies for source items, applying processor-intensive effects later
in the process, making sure that you use RAM effectively, and other performance-enhancing measures can improve
rendering and screen redraw speed.

Output type considerations

The suggestions that follow can help you select composition settings for specific media. However, the best way to
ensure that your project is suitable for a specific medium is to make a test composition and view it using the same
type of equipment that your audience will use to view it.

Film or videotape

If you'll be rendering for film, consider both the aspect ratio of the frame size you select for your composition and
the frame rate of your source footage. For footage that was transferred from film to video using the 3:2 pulldown
telecine method, you must remove 3:2 pulldown before adding effects. (See "To remove 3:2 or 24Pa pulldown from
video" on page 102.)
For film and video, try to match import and composition settings with settings in the output module used to render
a movie. In some cases, you may want to conform footage to a frame rate different than the frame rate of the source
footage. For example, you may want to conform 25 fps PAL to 24 fps for film.
The composition frame size should be determined by the image size in the playback medium.
