referenced. Text characters are added as vectors once and then referenced on all subsequent frames, unless you choose Fill Over Stroke from
the Fill And Stroke options menu; in that case, the characters are added as vectors on every frame.
If color management is enabled for the project, then colors are converted from the working color space of the project to the sRGB
IEC61966-2.1 color space for output. This output color space is appropriate for movies shown in a web browser. (See Color management.)
1. Select the composition you want to export, and then choose File > Export > Adobe Flash Player (SWF).
2. Enter a filename (making sure to include the .swf extension) and location, and then click Save.
3. Specify options as appropriate, and then click OK.

SWF export settings
Specifies the quality of rasterized images. The higher the quality, the larger the file. (If you select Rasterize for Unsupported
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.)
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.
The bit rate of the exported audio. Choose Auto to get the lowest bit rate available for the specified Sample Rate and Channels
settings. Higher bit rates increase file size. Audio in a SWF file is in MP3 format.
Specifies that the exported SWF file loops continuously during playback. If you plan to specify looping by writing HTML code
to control Flash Player, deselect Loop Continuously.
Creates a SWF file that can’t be modified by applications such as Flash Professional.
Includes layer, mask, and effect names in the file, for use as input to ActionScript programs. Selecting this option
increases file size. Rasterized objects are not named.
Each mask is exported as a separate SWF object, the name of which is the layer name followed by the mask name. If all masks use Difference
mode, all masks are exported as one SWF object, and the name is the layer name. Each text character is exported as a separate SWF object.
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.)
Flattening Illustrator artwork has advantages and disadvantages. When you flatten Illustrator artwork, text is exported to SWF format 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 are exported 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.
Makes layer markers behave as web links. The Include Layer Marker Web Links option adds web links and a
Get URL action to the SWF file by using information from layer markers. This option also adds a frame label to each SWF frame that has a layer
marker. You can specify how the browser opens the web link with standard target commands (for example, _blank). (See Web links, chapter links,
cue points, and markers.)
