Gentlemen:
         
     We have assisted in the preparation of a Registration Statement on Form S-8
(the "Registration Statement"), to be filed with the Securities and Exchange
Commission, relating to 800,000 shares of common stock, $.01 par value per share
(the "Shares") of Avid Technology, Inc. (the "Company"), issuable under the
Company's 1994 Stock Option Plan, as amended (the "Plan").

     We have examined the Third Amended and Restated Certificate of
Incorporation and the By-Laws of the Company and all amendments thereto, the
Registration Statement and originals, or copies certified to our satisfaction,
of such records of meetings, written actions in lieu of meetings, or resolutions
adopted at meetings, of the directors of the Company, documents and such other
documents and instruments as in our judgment are necessary or appropriate to
enable us to render the opinions expressed below .

     In examination of the foregoing documents, we have assumed the genuineness
of all signatures and the authenticity of all documents submitted to us as
originals, the conformity to original documents of all documents submitted to us
as certified
 or photostatic copies, and the authenticity of the originals of
such latter documents.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares have been duly and validly authorized for issuance under the Plan and the
Shares, when issued against payment therefor in accordance with the terms of the
Plan, will be legally issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement.

                                        Very truly yours,
