Optimizing movies

As your movie file size increases, so does its download time and playback speed. You can take a number of steps to prepare your movie for optimal playback. As part of the publishing process, Flash automatically performs some optimization on movies: for example, it detects duplicate shapes on export and places them in the file only once, and it converts nested groups into single groups.

Before exporting a movie, you can optimize it further by using various strategies to reduce the file size. You can also compress a SWF file as you publish it. (See Publishing in Using Flash.) As you make changes, run your movie on a variety of different computers, operating systems, and Internet connections.
