To correct the image size when encoding using Flash Video Encoder, deselect the Maintain
Aspect Ratio check box in the Advanced Encoding Settings dialog box, and enter the
corrected dimensions at which to encode the video. For more information, see
"Selecting
advanced video encoding settings" on page

About encoding audio-only files
The same considerations exist for audio production as for video production. To achieve good
audio compression, you must begin an audio file that is free of distortion and audible artifacts
introduced from the source recording. If you are encoding material from a CD, try to record
the file using direct digital transfer rather than your sound card's analog input. The sound
card introduces an unnecessary digital-to-analog and analog-to-digital conversion that can
create noise in your transferred audio. Direct digital transfer tools are available for both
Windows and Macintosh platforms. If you must record from an analog source, use the highest
quality sound card available.
About cue points
Cue points cause the video playback to start other actions within the presentation and let you
synchronize the video with animation, text, graphics, and other interactive content. For
example, you can create a Flash presentation that has video playing in one area of the screen
while text and graphics appear in another area.
Each cue point consists of a name, the time at which it occurs in the video, type of cue point,
and optional parameters. You specify cue point times using the format:
hour:minute:second:millisecond. When the encoded FLV file is played back within a Flash
SWF file, and the FLV plays or seeks to the elapsed time specified by the cue point, the action
you've specified is triggered.
Flash Video Encoder lets you embed cue points in video clips using the Advanced Settings
dialog box. You can assign each cue point an event type and parameter that can be used with
ActionScript or the Flash FLVPlayback component to programmatically cause the video
playback to start other actions in the presentation.
