Introduction To SMIL Scripting Guide for QuickTime

SMIL (pronounced “smile”) stands for Synchronized Multimedia Integration Language. SMIL is a Web Consortium standard for describing multimedia presentations. QuickTime 4.1 and later can play many kinds of SMIL presentations as if they were QuickTime movies.

If you are a content author, webmaster, or QuickTime developer, you can use SMIL to create multimedia presentations that play from the desktop or over the web using the QuickTime plug-in, ActiveX control, or the QuickTime Player application.

This document provides a general overview of SMIL and a detailed description of its usage in QuickTime.
