There are two ways to select your source media. You may either:
select "Select Input" under the "Encoding" menu.
on the "File" tab, click the "Browse…" button to the right of the "Input:" text field.
Either method brings up the Open file dialog. Simply select your file and click the "Open" button. (You may also manually enter your file path into the input field, but be sure to get it exactly right!) For a complete list of acceptable file types, please view Supported Formats.
Set Output Name
Once you have chosen your input media, select a path and name for your SWF output. You may either:
select "Set output" under the "Encoding" menu.
under the "File" tab, click the "Browse…" button to the right of the "Output:" text field.
Either method brings up the Save As dialog box. You may navigate to any directory and then choose a name. (As with the "Input:" field, you may also manually enter your file path into the output field, but again be sure to get it exactly right!)
Choose Outputs
You may choose whether to export audio and/or video in your SWF, by checking the appropriate boxes. Of course, if your source is audio-only, you will not be able to export video, and if your source has no audio track, only the "Export Video" option will be available.
If you wish to deploy your SWF in a web page, you may select "Export HTML", which will produce an HTML file with the OBJECT EMBED tags necessary to embed the SWF in a web page. Simply copy that code into any HTML document.
