Choosing a Video Codec

The Windows Media Video 9 Encoder supports three categories of encoded output: Main Profile, Advanced Profile, and Image. The Main Profile category provides general video compression for complex video content, such as movies or music videos. The features of the Main Profile provide for a wide range of encoding settings. You can use the Main Profile to create video with very low bit rates for delivery on handheld devices or, at the other end of the spectrum, you can use it to create high-definition video for digital cinema.

The emphasis of the encoding algorithms in the Main Profile is on dynamic video content, but they are suitable for other video content as well. The Main Profile should be your default category for video content. To meet specific needs, you can use the Advanced Profile category, the Image category, or a separate encoder called the Windows Media Video 9 Screen encoder. The following table lists the four options.
