Exporting for Adobe Media Player

Adobe Media Player is designed to play FLV files, either streaming from a server or played back from a local hard disk.

With Adobe Media Encoder, you can export FLV files for playback in the Adobe Media Player. Select FLV | F4V from

the Format menu in theExport Settings dialog box. Then, select specific settings to meet the requirements of the FLV

host or your target audience.

For information on selecting an FLV codec in the Export Settingsdialog box, see About the On2 VP6 and Sorenson

Spark Video Codecs on the

Capturing And Encoding Video page on the Developer Center website.

For information about choosing the best video, audio, encoding, and bit rate settings for your target audience, see the

Flash video (FLV) bitrate calculator on the Developer Center website.
