The FLV Export plug-in supports the following video-editing applications:
•
Adobe After Effects (Windows and Macintosh)
•
Apple FinalCut Pro (Macintosh)
•
Apple QuickTime Pro (Windows and Macintosh)
•
Avid Xpress DV (Windows and Macintosh)
Using the FLV QuickTime Export plug-in to export FLV files from either Flash Video Encoder or other video-editing
applications significantly streamlines working with FLV files in your Flash documents. With the FLV Export plug-
in, you can select encoding options for video and audio content as you export, including frame rate, bit rate, quality,
and other options. You can import FLV files directly into Flash without re-encoding the video after import.

Select a video encoding profile
Encoding profiles are based on the Flash Player version you intend to publish content for, and the data rate at which
you want your video content to be encoded. An encoding profile using Flash Player 8 uses the On2 VP6 video codec.
An encoding profile using Flash Player 7 uses the Sorenson Spark video codec to encode the video.
1
In the Encoding panel, select an encoding profile from the Flash Video Encoding Profile pop-up menu.
2
Verify that the encoding profile you’ve selected is appropriate for your intended application.
3
Do one of the following:
•
To further adjust the encoding settings, or to modify the video clip’s size or playback length using the crop-and-
trim controls, click the Video or Crop and Resize tabs.
•
To encode the video, click Continue.

Specify advanced encoding settings
1
To specify advanced encoding options, select the Video tab.
2
Select a video codec to encode your content with from the Video Codec pop-up menu. If you are authoring for
Flash Player 6 or 7, choose the Sorenson Spark codec; if you are authoring for Flash Player 8 or later, choose the On2
VP6 codec.
3
Select a frame rate.
By default, Flash Video Encoder uses the same frame rate as the source video. Adobe® recommends using the default
frame rate unless you are experienced with video encoding, and have a specific application that requires modifying
the source video’s frame rate. To alter the frame rate, understand how modifying the frame rate affects the video
quality.
Note: To embed video clips in the SWF file, the frame rate of the video clip must be the same as that used by the SWF
file. To encode video using the same frame rate as the FLA file, use the Video settings in the Video Import wizard.
4
Select the keyframe placement for the video. Keyframes are video frames that contain complete data. For example,
if you specify a keyframe interval of 30, Flash Video Encoder encodes a complete frame every 30 frames in the video
clip. For frames between keyframe intervals, Flash stores only the data that changes from the preceding frame.
