Microsoft Expression Encoder 4 is a program for creating high-
quality audio and video that you can play back, or stream,
seamlessly from the web, using Internet Information Services
(IIS) Smooth Streaming* technology. Expression Encoder gen-
erates high-quality VC-1-encoded and, in Expression Encoder
Pro**, H.264-encoded content. This content integrates well
with the rich-media, interactive-presentation capabilities of
Microsoft Silverlight. You can also use the Expression Encoder
Screen Capture application to capture activity on your screen,
and then save it to stream or edit further in Expression Encoder.
This version adds the ability to streamline your workflow by
working in one of three project-specific workspaces: Transcod-
ing Project, Silverlight Project, or Live Broadcasting Project.
Expression Encoder Pro adds the ability to use Digital Rights
Management (DRM) protection for your smooth streaming*
content. Using the tools in Expression Encoder, you can encrypt
and encode files that are compatible with Microsoft PlayReady
technology. With DRM, you can be confident that your media
will be used only as you specify.
For a complete list of new features, see “What’s new” in the
Expression Encoder User Guide (on the Help menu).
*Available in Expression Encoder Pro only.
