Where SMIL excels at flexibility, Electrifier Pro excels at tidiness. Inspectors allows for tweaking. Electrifier Pro comes with numerous effects, transitions, and actions. Most authoring is accomplished by clicking and dragging. Place your media on to the stage and then drop an effect on top of the media.
Attributes are adjustable in property inspector boxes.
Your only limitation is the bandwidth of your Web site user. The biggest catch in any Web multimedia authoring tool is getting to know the program. The one constant in any multimedia authoring tool is a timeline. But unfortunately, how you interact with that timeline varies widely from tool to tool. So while Electrifier Pro is a relatively easy to learn tool, don't expect to pick it up instantly.
