The following MC-IF Work Groups have been established. If you are interested in participating in these Work Groups, please reach out to the respective Work Group Chairs.

IP Ecosystem Work Group

Chair: Stephan Wenger

  1. Collect, summarize, and analyze available information pertaining to the IP licensing ecosystem of previous/contemporary media compression standards, to include MPEG Standards such as H.264/AVC and HEVC, and other codecs such as VP9 and AV1, to the extent that the review of such other codecs can inform the discussion of the Work Group and support the mission of MC-IF to promote MPEG Standards such as VVC (and other MPEG Standards, as applicable or as requested by the Board).

  2. Within the confines of antitrust and competition laws, identify possible mechanisms to improve the future IP licensing ecosystem of VVC, and other MPEG Standards as requested by the Board.

  3. Identify whether, and to what extent, MC-IF can assist in creating/maintaining such mechanisms, and implement as requested by the Board.


Profiling Work Group
Chair: Jill Boyce 

  • Identify need for profiling, sub-profiling, constraint flags, and sets thereof, initially for VVC

  • Communicate MC-IF requests or recommendations to relevant bodies, including VCEG, MPEG

  • Define a process for MC-IF to use to serve as a registration authority for sub-profiles, initially focusing on VVC

Marketing and Outreach Work Group

Chair: Jonatan Samuelsson

  • Manage MC-IF visibility and messaging by

    • Mentions and placements in articles, journals, and at events

    • Managing social media accounts and website, and promote visibility of MC-IF in other social media

  • Manage MC-IF outreach and recruitment by

    • Identifying suitable venues and local organizers for outreach events; organize and promote such events

    • Initiating and fostering conversations with potential new members

  • Promote standards identified by the membership as priorities, including:

    • The technical, business, and ecosystem advantages of the selected standards;

    • The industry needs, use cases and business opportunities enabled by these standards;

    • The importance of these standards to the ecosystems (open, FRAND, pro-competition).

  • Achieve these promotion goals by:

    • Putting information on the web including social media and mailing lists, in articles and journals, white-papers;

    • Presenting at selected trade shows and other events.

    • Perform other communication as needed or requested by the board

Interop Work Group

Chair: Lukasz Litwic


  • Identify needs of interoperability, testing and implementation beyond what’s done by the standards committees (e.g. ISO/IEC, DASH-IF)

  • Promote interoperability via tools, bitstreams, online and face to face interoperability testing

  • Encourage publication of interoperability results and status in a way that encourages broad participation

  • Document, inspire and provide implementations to support potential implementors of the standard and assessment of interoperability. One example: VVC implementation that can be exposed under FFmpeg.

  • Develop and maintain online resources of interoperability test bitstreams, tools, validators, reference code, guidelines, and other resources


All participant conduct under these Work Group Charters is required to be in compliance with the MC-IF Bylaws, and MC-IF’s official policies and procedures, available at
