Authoring Guidelines

Authoring for Flash Player 33

To use the new Flash Player, you will need to target SWF version 44 by passing "- swf -version=44" as an extra compiler argument to the ASC 2.0 compiler.  Detailed directions are below.

• Download the new playerglobal .swc for Flash Player 33
• Download and install Flash Builder 4.7 from Creative Cloud: https://creative.adobe.com/products/flash-builder
• In Flash Builder, create a new project: File -> New -> project.
• Open the project Properties panel (right-click and chose 'Properties'). 
• Select ActionScriptCompiler from the list on the left.
• Add "-swf-version=44" to the 'Additional compiler arguments' field.
  • This ensures the outputted SWF targets SWF version 44.  If you compile on the command-line and not in Flash Builder, you need to add the same compiler argument.
• Ensure you have installed the new Flash Player 33 build in your browser.

When reporting an issue involving video, it is essential to note your graphics hardware and driver, along with your operating system and browser (when using Flash Player), so that we can reproduce and investigate issues. Please be sure to include this information as described in Instructions for Reporting Video Playback Issues.
