FLASH CS3 453 User Guide You must set your Publish settings to Flash 5 or earlier to publish QuickTime with Flash track. This means you cannot use Flash features implemented after Flash 6. Note: Beginning with QuickTime 7.1.3, the use of Flash tracks were disabled by default. To publish a QuickTime file with a Flash track using QuickTime 7.1.3 or later, select Edit > Preferences > QuickTime Preferences > Advanced Media Types within QuickTime, and enable the use of Flash tracks. Exports all layers in the Flash document as a single Flash track, unless the document contains an imported QuickTime movie. The imported QuickTime movie remains in QuickTime format in the exported application.

By default, QuickTime export creates a movie file using the same dimensions as the source Flash document, and exports the Flash document in its entirety. The Export QuickTime Video dialog box contains the following options: Dimensions The width and height in pixels for the frames of the QuickTime movie. You can specify only the width or the height; the other dimension is automatically set to maintain the aspect ratio of your original document. To set both the width and the height independently of each other, deselect Maintain Aspect Ratio. Note: If the dimensions of the video is particularly large (for example, 740 x 480 pixels), you may need to change the frame rate of the Flash movie to avoid dropping frames. Note: The Dimensions you set in the QuickTime Export Settings dialog is for the width and height of the Flash movie exported as video. The dimensions you set in the QuickTime Settings dialog specifies the size of the exported QuickTime movie. If you do not change the size in the later dialog, it remains as "current" so you do not need to change it. Ignore stage color Creates an alpha channel using the stage color. The alpha channel is encoded as a transparent track, letting you overlay the exported QuickTime movie on top of other content to alter the background color or scene. To create a QuickTime video with an alpha channel, you must select a video Compression Type that supports 32 bit encoding with an alpha channel. Codecs that support this are Animation, PNG, Planar RGB, JPEG 2000, TIFF, or TGA. You must also select Million of Color+ from the Compressor/Depth setting. To set the compression type and color depth, click the Setting button in the Video category of the Movie Settings dialog box.
