User Guide
Adobe Flash is intended for progressive display on computer screens and other devices, rather than on interlaced
displays such as TVs. Interlaced footage viewed on a progressive display can exhibit alternating vertical lines in high-
motion areas. Thus, all the Adobe Flash Video presets in the Adobe Media Encoder have deinterlacing turned on by
default.
Follow the same guidelines for audio
The same considerations apply to audio production as to video production. To achieve good audio compression,
begin with clean audio. If you are encoding material from a CD, try to record the file using direct digital transfer
instead of through the analog input of your sound card. The sound card introduces an unnecessary digital-to-analog
and analog-to-digital conversion that can create noise in your source audio. Direct digital transfer tools are available
for Windows and Macintosh platforms. To record from an analog source, use the highest-quality sound card
available.
Working with Flash and After Effects
If you use Adobe® Flash® to create video or animation, you can use After Effects® to edit and refine the video. For
example, you can export Flash animations and applications as QuickTime movies or Flash® Video (FLV) files. You
can then use After Effects to edit and refine the video.
If you use After Effects to edit and composite video, you can then use Flash to publish that video. You can also export
an After Effects video as Flash content for further editing in Flash.
Exporting QuickTime video from Flash
If you create animations or applications with Flash, you can export them as QuickTime movies using the File >
Export Movie command in Flash. For a Flash animation, you can optimize the video output for animation. For a
Flash application, Flash renders video of the application as it runs, allowing the user to manipulate it. This lets you
capture the branches or states of your application that you want to include in the video file.
Exporting Flash video (FLV) from After Effects
When you render finished video from After Effects, select FLV as the output format in the render queue to export
directly to the Flash Video (FLV) format. This launches the Flash Video Encoder application, which provides size,
compression, and other output options. Any After Effects markers are added to the FLV file as cue points.
You can then import the FLV file into Flash and publish it in a SWF file, which can be played by Flash Player.
Importing and publishing video in Flash
When you import a FLV file into Flash, you can use various techniques, such as scripting or Flash components, to
control the visual interface that surrounds your video. For example, you might include playback controls or other
graphics. You can also add graphic layers on top of the FLV file for composite effects.
Composite graphics, animation, and video
Flash and After Effects each include many capabilities that allow you to perform complex compositing of video and
graphics. Which application you choose to use will depend on your personal preferences and the type of final output
you want to create.
Flash is the more Web oriented of the two applications, with its small final file size. Flash also allows for runtime
control of animation. After Effects is oriented towards video and film production, provides a wide range of visual
effects, and is generally used to create video files as final output.
