If I own Adobe Flash CS3 why do I need Flix?
Flix has many advantages over the video import functions in Adobe’s Flash authoring tools. Flix provides 2-pass VBR encoding, which delivers significantly better video quality than single-pass. Flix also contains features not available in the Adobe tools (or are much faster to use), such as batch encoding, automatic player output, automatic preloaders, and automatic Flash functions. In addition, Flix Pro is the only software available that will convert video files to a vector-based SWF animation.
