The Video Properties dialog box appears.
If you don't see the desired video file listed in the Open dialog box (or if you can see it but can't select it), select All Files (*.*) from the Files Of Type pop-up menu (Windows), or All Files from the Enable pop-up menu (Macintosh). This is necessary sometimes because the Flash authoring tool doesn't recognize most device video formats.
In the Video Properties dialog box, select the Export For ActionScript option and enter a string in the Identifier text box to play the device video clip by using a separate video object on the Stage. For more information, see Playing a bundled video directly from the library.
A new video symbol appears in your document's Library panel that's associated with the device video file. You can edit the video symbol's properties in the Video Properties dialog box. For more information, see View and edit device video symbol properties.
