SWF Output
SWF video is another output option, but these files are limited to 16,000 frames or fewer, so at a SWF frame rate of 8 fps your movie cannot be more than 33 minutes long. The Flash player stops playing your video after 16,000 frames and Flix Pro warns you if your output video will exceed this.
Your SWF video should not 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. Flix Pro lets you know how much RAM your video and audio uses when it is loaded into the Flash player, and warns you when you exceed 50MB.
