Storyline 360: Flash Movie Best Practices

Article Last Updated

This article applies to:

Storyline 360 supports interactive and non-interactive Flash movies. These guidelines will help you develop Flash movies that work properly in your Storyline courses.

Flash Settings

If you're creating files in Adobe Flash, use these settings:

Player Version: Storyline publishes content for Flash Player version 10. Therefore, you should publish your Flash movies for Flash Player 10 or lower.

Frame Rate: Storyline publishes at a rate of 30 frames per second. Create your Flash movies at 30 frames per second, so they play at the correct speed in Storyline.

File Name: Follow sound web naming conventions for your Flash files. Don't use spaces, periods, or special characters. Use only letters, numbers, hyphens, and underscores.

Test Flash movies outside of Storyline: We recommend testing your Flash movies in a standalone player, such as Swiff Player. Often, a standalone player shows you the duration, frames per second, Flash Player version at which it was published, and other details. Compare them against the best practices described here. Also, a standalone player lets you see how your Flash movies behave outside of Storyline, so you can compare the results to how they operate in Storyline.


If your Flash movies contain ActionScript, follow these guidelines:

Use ActionScript 3.0

Don’t use references to _root or _level0: If you use ActionScript 2.0 (not recommended), note that references to _root and _level0 can cause issues with the Storyline player and should be avoided. For more information on how to avoid using _root and _level0 references, please visit Adobe’s Flash Support Center.


Here's a list of known limitations when adding Flash content to Storyline:

  • SWF files won't work in HTML5 output.
  • SWF files won't work in the Articulate Mobile Player app.
  • FLV videos with alpha channel transparency aren't supported in HTML5 output.
  • Off-stage elements contained in a Flash movie (i.e., elements that extend beyond the movie's dimensions) will appear in Storyline. So even though off-stage elements are hidden in the Flash movie, they won't be hidden in Storyline. You should mask them in the original file and republish as a Flash movie. If you don't have access to the original file, you may be able to mask the off-stage elements by inserting the Flash movie into a scrolling panel and resizing the scrolling panel to hide the off-stage elements of the Flash movie. This option may not work for all Flash files, so you'll need to test it to be sure.
