Step 5- Start a new project in Microsoft Expression Encoder

If you just need to add captions to your Windows Media video then start a new Transcoding Project. Alternately, if you want to encode a video that is compatible with Silverlight and can be embedded in a rich, interactive Silverlight template, then start a Silverlight Project.
