    Please ensure that your talk follows the guidelines outlined in the Code of Conduct for USENIX Events and Online Community Spaces.
  5. Prepare and Submit Your Presentation Videos and Slides.
    For our virtual events, you are required to record a video of your talk that integrates your slides with footage of you speaking. Your video and slide deck are due via our Box upload link by Tuesday, May 4, 2021. This video will be played live for you by the USENIX staff during the conference at your designated time slot in the program.

Use of Images, Audio, and Video in Your Materials

It is very important that you secure permission to use copyright-protected materials in your slide deck, video, or other materials used at a conference or submitted for publication. Even when an item has a Creative Commons license, you must read and comply with the terms of the license.

USENIX receives copyright infringement notices from time to time, resulting from authors or speakers using copyright-protected materials without proper licensing or attribution. When this happens, we have to unpublish the work in question until/unless the issue is resolved. Licensing fees may be incurred, even when the work is unpublished, and USENIX will bill the author or speaker for any costs incurred. When possible, USENIX will refer the complainant directly to the author or speaker, who will be solely responsible for resolving the complaint.
