Any block that extends above the red line in the graph indicates a frame at which the Flash Player may halt playback until the entire frame downloads. You can also generate a report to find frames that are slowing playback, and then optimize or eliminate some of the content in those frames. To generate a report, use the Select Generate Report option in the Publish Settings dialog box. 2 Select Generate Size Report. 3 Click Publish.
Flash generates a text file with the same name as the exported movie plus the .txt extension.
The report lists the amount of data in each frame of the final Flash Player file. See Flash Tech Note 12085 for more information on how to analyze a Size Report. Inc. All rights reserved.
