contains fields. If you require interlaced fields, render the movie normally.

Exporting footage using QuickTime components
If you have QuickTime 4.1 or later installed on your system, you can export items using
components provided by QuickTime. This rendering process exports the movie directly
without using the Render Queue window in After Effects. The specific file formats you can
export to depend on how you've configured QuickTime. If you install new export modules
as they become available from Apple or other third parties, those modules will appear on
the File > Export submenu in After Effects. With this QuickTime support, you can export
AVI files on both platforms or prepare streaming video and audio for Web distribution. If
you want to apply QuickTime effects, you can do so during export.
For more information about effects and file formats supported by QuickTime, start the
QuickTime Player program included with QuickTime 4.1 and choose Help > On-line
QuickTime Player Help.
Note: The composition is exported using the Composition window's current quality and
resolution settings. Only the work area in the Time Layout is exported.
To export files using QuickTime export formats:
1 Select an item in the Project window.
2 Choose File > Export, select the export module you want to use, specify options as
necessary, and click Save.
Rendering an item to multiple formats
You can apply more than one output module to each render item in the queue. This is
useful when you want to make more than one version of a movie. For example, you can
automate the creation of a movie and its alpha matte, or you can create high-resolution
and low-resolution versions of a movie.
When you apply more than one output module to a render item, After Effects renders to
the various output formats simultaneously, saving you time.
To apply an additional output module:
1 In the Render Queue window, select an item.
2 Choose Composition > Add Output Module.
Choosing compression options
Compression is essential to reduce the data size of movies that would otherwise be so
large as to prohibit effective playback. When compressing a movie file, you can fine-tune it
for the best-quality playback on a computer, on a video playback device, on the Web, or
from a CD-ROM drive.
