Testing Your Movie
You can quickly preview your animation by “scrubbing” the red playhead back and forth on the Timeline or by choosing Control > Play. You can also use the integrated Controller at the bottom of the Timeline.
However, to preview your animation as your audience will see it and to preview any nested animations within movie clip symbols, you should test your movie. Choose Control > Test.
Animate exports the published files—in this case, a SWF file—and saves them in the same location as your FLA file. The SWF file is the compressed, final Animate media that you would embed in an HTML page to play in a browser with the Flash Player. Animate displays the SWF file in a new window with the exact Stage dimensions and plays your animation.
Test your movie for both your 04CameraStart.fla document and your 04_workingcopy.fla document.
To exit Test Movie mode, click the Close window button.
You can also preview your animation by choosing Control > Test Movie > In Browser, and Animate will export a SWF file and open it automatically in your default browser.
