Windows AVI is the standard Windows movie format and is a good format to use if you want to open a Flash animation in a video-editing application. Since AVI is a bitmap-based format, movies that contain long or high-resolution animations can quickly become very large.
The Windows AVI Export options dialog box contains the following options:
Dimensions Specifies a width and height in pixels for the frames of an AVI movie. Specify only the width or the height; the other dimension is automatically set to maintain the aspect ratio of your original movie. Deselect Maintain Aspect Ratio to set both the width and the height.
Video Format Selects a color depth. Many applications do not yet support the Windows 32-bit image format. If you have problems using this format, simply use the older 24-bit format.
Smooth Turns Flash anti-aliasing on in the exported AVI movie. Smoothing produces higher quality images. However, a halo of gray pixels may appear around an image placed on a colored background. Export without smoothing if a halo appears.
Compress Video Displays a dialog box for choosing standard AVI compression options.
