If you want to get Flash video on your website there are a couple things you need to understand.
First, something technical. The Flash videos you watch online consist of two parts, an FLV file, which is your actual video, and an SWF file, which is the player that displays the video.
Now, something non-technical. You don't need to know anything about programming or even own Flash software in order to create high-quality, customized FLVs and SWFs.
All you need is to read my new guide, How to Get Flash Video on Your Website. It offers free resources for converting your video files to FLVs, online tools for customizing SWFs, and step-by-step instructions for streaming Flash videos from your website. That's a whole lot easier than investing in and learning CS4!
