The QuickTime Video option is available on Macintosh systems only. It exports using the QuickTime 3 file format, so all Flash content is bitmapped. Using this option, a Flash movie loses all of its interactivity. This format is useful if you want to change Flash content in a video editing application.
The QuickTime Video Export options dialog box contains the following options:
Size Specifies a width and height in pixels for the frames of a QuickTime movie. By default, you need specify only the width or the height and the other dimension are automatically set to maintain the aspect ratio of your original movie. If you deselect Maintain Aspect Ratio, you can set both the width and the height.
Format Selects a color depth.
Smooth Turns Flash's anti-aliasing on and off in the exported QuickTime movie. This improves the appearance of the bitmapped frame images. However, anti-aliased images might have a halo when placed over a colored background.
Compressor Selects a standard QuickTime compressor.
Quality Controls the amount of compression applied to your movie. The exact effect depends upon the compressor selected.
Sound Format Sets the export rate for sounds in the movie. Higher rates yield better fidelity and larger files. Lower rates save disk space.
