Use clean video
The higher the quality of the original, the better the final result. Although frame rates and sizes of Internet video are
usually smaller than those of television, computer monitors have much better color fidelity, saturation, sharpness,
and resolution than conventional televisions. Even with a small window, image quality can be more important for
digital video than for standard analog television. Artifacts and noise that are barely noticeable on TV can be obvious
on a computer screen.
Remove noise and interlace
After you capture your video content, you might need to remove noise and interlacing.
Follow the same guidelines for audio
The same considerations exist for audio production as for 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.

Encoding video
About Flash Video encoding methods
The following sections describe the encoding settings, crop-and-trim controls, and for users of either the Flash Video
Encoder or FLV QuickTime Export plug-in, the cue point embedding controls.
Flash Video Import wizard
The Flash Video Import wizard encodes video clips into the Flash Video (FLV) format when you import them.
However, you can only encode one video clip at a time, and the process of encoding can be both time- and
computing-intensive.
For users who work extensively with video-based content, Flash includes the Flash Video Encoder and the
QuickTime Exporter.
Flash Video Encoder
The Flash Video Encoder batches process video clips, allowing you to encode several clips at a time without having
to interrupt your workflow. In addition to selecting encoding options for video and audio content, the Flash Video
Encoder can also embed cue points into video clips you encode, and edit the video using crop-and-trim controls.
For more information, see the online help included with the Flash Video Encoder application.
FLV QuickTime Export plug-in
If you have Flash 8 or later and QuickTime 6.1.1 installed on your computer, you can use the FLV QuickTime Export
plug-in to export FLV files from supported video-editing applications. You can then import these FLV files directly
into Flash.
