711 USING AFTER EFFECTS CS4
Rendering and exporting
Last updated 12/21/2009
Include Layer Marker Web Links 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 ” on
page 621.)
Target commands for web links in a SWF file
_blank Loads the web link into a new browser window.
_parent Loads the web link into the parent frame of the frame in which the current file is playing.
_self Loads the web link into the current frame.
_top Loads the web link into the top frame in the current window.
_level0 Loads another SWF file into level 0. The current file typically plays at level 0; another file loaded into level 0
usually replaces the current file. The URL must refer to another SWF file.
_level1 Loads another SWF file into level 1 if the URL refers to another SWF file.
Supported features for SWF format export
Layers After Effects text layers are exported to SWF format as vector graphics. The following layer types and layer
switches aren’t supported: track mattes, 3D layers, 3D cameras, 3D lights, adjustment layers, shape layers, Preserve
Transparency, Collapse Transformations, and motion blur. The Fill Over Stroke character option and the Blur
animator property aren’t supported, and only Normal blending mode is supported. Nested compositions aren’t
supported and are rasterized.
Masks Only masks with Add mask mode or Difference mask mode are supported; multiple masks in a layer must use
the same mask mode. If Add mode is specified, partial opacity and the Inverted option are also supported. Mask feather
is not supported. The result of overlapping masks with Add mode and partial opacity may appear differently in the
SWF file than in After Effects. (See “
Mask modes ” on page 377.)
Effects Path Text, Audio Waveform, and Audio Spectrum are supported for output to SWF format.
All Path Text options are supported, except the following: Composite On Original, Fill Over Stroke, and Difference mode.
Lines drawn by the Audio Spectrum and Audio Waveform effects are converted to vectors. The following unsupported
features are ignored: Outside Color (only Inside Color is used), Softness, and Composite On Original. In addition, only
uniformly thick lines are included in the SWF file. For example, if you select the Use Polar Path option in Audio
Spectrum, lines become thicker farther from the center in After Effects, but in the SWF file the lines remain at the same
thickness.
The waveforms may increase the SWF file size, so decrease the Displayed Samples value in the Audio Waveform effect
or the Frequency Bands value in the Audio Spectrum effect, or decrease the frame rate to make the SWF file smaller.
Resolution SWF files are always created at full resolution (size of composition); JPEG-compressed bitmap images are
rendered at full resolution.
Adobe Illustrator files Only stroked paths and filled paths in CMYK or RGB color spaces are supported.
Layers that have Illustrator source files are converted to corresponding SWF items if the layer does not contain masks
or have Collapse Transformations enabled. Illustrator layers that contain masks or have Collapse Transformations
enabled are rasterized. The SWF file maintains the Illustrator crop marks. Artwork outside the crop marks is included
in the SWF file even though it’s not visible, thereby increasing the file size.
