Exhibit 31.2

                                  CERTIFICATION

    I, Paul J. Milbury, certify that:

1.  I have reviewed this Quarterly Report on Form 10-Q of Avid
    Technology, Inc.;

2.  Based on my knowledge, this report does not contain any untrue
    statement of a material fact or omit to state a material fact
    necessary to make the statements made, in light of the circumstances
    under which such statements were made, not misleading with respect to
    the period covered by this report;

3.  Based on my knowledge, the financial statements, and other financial
    information included in this report, fairly present in all material
    respects the financial condition, results of operations and cash
    flows of the registrant as of, and for, the periods presented in this
    report;

4.  The registrant's other certifying officer and I are responsible for
    establishing and maintaining disclosure controls and procedures (as
    defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
    registrant and have:

    a)  Designed such disclosure controls and procedures, or caused such
        disclosure controls and procedures to be designed under our
        supervision, to ensure that material information relating to the
        registrant, including its consolidated subsidiaries, is made known to
        us by others within those entities, particularly during the period in
        which this report is being prepared;

    b)  Evaluated the effectiveness of the registrant's disclosure controls
        and procedures and presented in this report our conclusions about the
        effectiveness of the disclosure controls and procedures, as of the
        end of the period covered by this report based on such evaluation;
        and

    c)  Disclosed in this report any change in the registrant's internal
        control over financial reporting that occurred during the
        registrant's most recent fiscal quarter (the registrant's fourth
        fiscal quarter in the case of an annual report) that has materially
        affected, or is reasonably likely to materially affect, the
        registrant's internal control over financial reporting; and

5.  The registrant's other certifying officer and I have disclosed, based
    on our most recent evaluation of internal control over financial
    reporting, to the registrant's auditors and the audit committee of
    the registrant's board of directors (or persons performing the
    equivalent functions):

    a)  All significant deficiencies and material weaknesses in the design or
        operation of internal control over financial reporting which are
        reasonably likely to adversely affect the registrant's ability to
        record, process, summarize and report financial information; and

    b)  Any fraud, whether or not material, that involves management or other
        employees who have a significant role in the registrant's internal
        control over financial reporting.
