     Company to Target Internet Desktops with
     Low-Cost, Consumer-Friendly Video Editing and
     Internet Streaming Applications--

MARLBORO, MA., December 28, 1999 - Media 100 Inc. (NASDAQ: MDEA), the
pioneer of streaming media production tools, today announced it has entered
into a definitive agreement to acquire Digital Origin Inc. (NASDAQ: DODV)
of Mountain View, California. Digital Origin is the leading developer of
digital video editing and effects software applications designed to support
the new low-cost, high-quality DV (digital video) camcorders, which rapidly
are being adopted as the standard for acquiring video for Internet
applications. The combined company will target Internet desktops with
low-cost applications that allow personal computer users to capture, edit,
and stream video on the Internet using a single, integrated, and
easy-to-use application. Digital Origin is the developer of the
award-winning applications EditDV and IntroDV, which provide Web site
designers, DVD authors, multimedia professionals, and consumers the ability
to create video programs -- complete with titles, effects and audio --
easily and a low-cost on a standard PC or laptop.

      The merger will be completed as a pooling of interests for accounting
purposes, and a tax-free transaction. Under the agreement, the Company will
issue 0.5347 shares of common stock for each share of Digital Origin common
stock. The transaction is subject to the approval of the stockholders of
Media 100 and Digital Origin and other customary closing conditions. The
merger is expected to be complete in 90 to 120 days.

      In addition, Media 100 and Digital Origin announced they have entered
into a non-exclusive, four-year OEM development and license agreement,
pursuant to which Media 100 will use the video editing and effects software
of Digital Origin in exchange for certain royalty payments. The parties
plan to integrate Digital Origin's software with Media 100's Internet
streaming media software, Media Cleaner, to deliver consumer-level video
editing and streaming tools to millions of Internet desktops.

      John Molinari, president and chief executive officer of Media 100,
said, "The merger with Digital Origin gives the combined company a
strategic technology and product portfolio unmatched in the streaming media
tools category. In combining Digital Origin's product and technology
portfolio with Media 100's, we will be the first company to offer fully
integrated Internet video production and streaming tools to all segments of
the market. We will address the video creation and streaming needs of a
broad range of customers, from consumers and Web site designers to video
professionals and high-end Internet broadcasters. Our tools address every
aspect of streaming media production from video capture, editing, and
effects to Internet streaming and DVD authoring.

       "The merged company's partnerships with DV camcorder leaders Canon,
JVC, and Panasonic, streaming media format suppliers Real Networks,
Microsoft, and Apple, and Internet service providers and portals such as
Excite@Home and encoding.com position us to create leading-edge streaming
media production tools and distribute them broadly to the Internet
desktop."

        Mark Housley, chairman and chief executive officer of Digital
Origin, said "The merger positions the new company as the premier supplier
of streaming media production tools for the Internet. By combining the
streaming media capabilities of Media Cleaner, developed by a Media 100
subsidiary, Terran Interactive, with Digital Origin's editing and effects
applications EditDV and IntroDV, we will deliver low-cost software
applications to Internet desktops that make it possible for millions of
users to create and stream video on the Web without forcing them to buy a
new, dedicated PC or Macintosh. We are eliminating the barriers of cost and
complexity to accelerate the growth of Internet video. Our goal is to make
everyone with a personal computer a potential Internet video broadcaster."

       Mr. Molinari added, "We plan to operate Digital Origin as a
wholly-owned subsidiary headquartered in Mountain View, California. We
project results of the acquisition to be accretive within the first year of
combined operations. The company will have approximately 100 employees in
its Silicon Valley hub, and will have an installed base in excess of
150,000 users."
