Lengthening a Movie with Static Frames

To plan for the changes of the movie over time, you need to add frames. Before adding frames, you at least need an estimate of the total run time of the movie (the time it takes for the movie to run from Frame 1 to the last frame in the timeline). By default, Flash plays 12 frames per second, or fps; therefore, if you want to create a movie that runs for 5 seconds, you'll need approximately 60 frames in the timeline. The movie as it stands is one frame long; the movie would take about .08 seconds to play through.

Tip

You can change a movie's frame rate by choosing Modify > Document from the main menu. The default rate of 12 is a good bet for most Web animations, though .

The Organic Farming Flash movie doesn't have an exact estimate of the running time, because it will stop for the user to press the Next button before it moves on to the next page. But it does have some animations, so you can estimate the length of the animations in seconds, multiply the number of seconds you want the movie to run by 12, and create that many new frames. The length of the animations will be about 8 seconds, so go ahead and add 93 more frames to the movie.

Remember, you can always drag the divider between the timeline and the Document window to make extra room.

Frame 96 in all eight layers is selected.

This step will insert (static) frames from Frame 2 to Frame 96 in all the layers in the timeline. The frame indicator is now in Frame 96. If any of the earlier keyframes had content, the subsequent static frames would have gray shading. Each of those frames would contain the same content as its preceding keyframe. Static frames that have no content are white.
