ADOBE AFTER EFFECTS 7.0
User Guide
610
Audio is encoded in MP3 format and added to the SWF file as an audio stream.
1
Select the composition you want to export, and then choose File > Export > Macromedia Flash (SWF).
2
Type a file name (making sure to include the .swf extension) and location, and then click Save (Windows) or OK
(Mac OS).
3
Specify options as appropriate, and then click OK:
JPEG Quality
Specifies the image quality. The higher the quality, the larger the file. (If you select Rasterize for Unsup-
ported Features, the JPEG Quality setting is used for all JPEG-compressed bitmap images exported to the SWF file,
including bitmap images generated from composition frames or Adobe Illustrator files.)
Unsupported Features
Specifies whether to rasterize features that SWF format doesn’t support. Choose Ignore to
exclude unsupported features, or choose Rasterize to render all frames that contain unsupported features as JPEG-
compressed bitmap images and include them in the SWF file. If you choose Rasterize, the SWF Exporter rasterizes
source files for each layer in the composition (except layers that use Illustrator files or solids as the source footage)
and nested compositions with Collapse Transformations enabled.
Audio Sample Rate
Specifies the sample rate of the audio.
Audio Channels
Specifies whether the audio tracks are mono or stereo.
Audio Bit Rate
Specifies the bit rate of the exported audio. Choose Auto to get the lowest bit rate available for the
specified Sample Rate and Channel. Higher bit rates increase file size. (See “To change output module settings” on
page 607.)
Loop Continuously
Specifies that the exported SWF file loops continuously during playback. If you plan to specify
looping by writing HTML code to control the Flash Player, deselect Loop Continuously.
Prevent Import
Creates a SWF file that digital image or video-editing programs can’t import.
Include Object Names
Includes layer, mask, and effect names in the file. Selecting this option increases file size. (See
“Including object names in a SWF file” on page 612.)
Flatten Illustrator Artwork
Splits all overlapping objects into non-overlapping pieces. When you select this option,
you don’t need to convert Illustrator text to outlines before exporting. (This option supports source files from
Illustrator 9.0 or later.)
There are advantages and disadvantages to flattening Illustrator artwork. When you flatten Illustrator artwork, text
exports to SWF properly, so you don’t need to convert text to outlines. Overlapping objects are removed, so
composited layers appear the same in both After Effects and the SWF file. End caps, joins, and transparency groups
export properly, and artwork outside crop marks, which is not visible in the SWF file, is not included. However, SWF
files don’t necessarily become smaller. In addition, the flattening process may introduce unsupported objects that are
then ignored or rasterized, and white fringes may appear around some objects. The process can be slow, memory-
intensive, and possibly ineffective for complex Illustrator artwork.
Include Layer Marker Web Links
Makes layer-time markers behave as web links. (See “Including web links in a SWF
file” on page 612.)
The SWF Exporter saves a report (
[SWF file name]
R.htm) to the same folder as the SWF file. Open the report in a
browser to see which items are unsupported in the SWF file.
