SWF Output
SWF video is another output option, but these files are limited to 16,000 frames or fewer at a SWF frame rate of 8 fps, so your movie cannot be more than 33 minutes long. Flash Player stops playing your video after 16,000 SWF frames, and some Flash encoders will warn you if your SWF output video will exceed 16,000 frames.
Your SWF video should also never exceed 50MB–60MB of Flash player’s RAM usage, which is determined by adding the file size to the overhead of the Flash player itself.
