Part of the motivation for PyCon is to help with Python education and advocacy around the world. Accordingly, we intend to record all PyCon presentations and release the recordings on the web (see [http://pyvideo.org/](http://pyvideo.org/ )). By submitting your talk or tutorial proposal, or by signing up to give a lightning talk, you agree to give permission to the Python Software Foundation to record, edit, and release audio and/or video of your presentation. We also perform interviews with poster presenters and require recording releases to publish them. By default, the recording release checkbox is checked when submitting a proposal. If you wish to opt-out, uncheck the release checkbox, note that no recordings of your talk will be made. You cannot opt out of recording for lightning talks. You agree to the following legalese, which certifies that you are the author of your presentation (or otherwise allowed to present it at PyCon), and which allows the Python Software Foundation 1) to perform the necessary audio and video editing needed to prepare your presentation, and 2) to distribute the recordings to other people, including on YouTube, or video sites. It also allows other people to watch the recordings. Legalese: I certify that I, the Submitter, am authorized to license this proposal and its associated presentation (the "User Submission") to the Python Software Foundation (the "PSF") for use in association with PyCon 2015. Specifically: - I, the Submitter, certify that I am either the copyright owner of the User Submission or an authorized licensee of the copyright owner. If I am an authorized licensee of the copyright owner, I certify that I have sublicensable distribution rights. - I, the Submitter, hereby grant the PSF a worldwide, royalty-free, fully paid-up, non-exclusive, perpetual (for the duration of the applicable copyright), sublicensable and transferable license to exercise the rights in the User Submission as follows: 1) The PSF is granted a license to reproduce the User Submission, to incorporate the User Submission into one or more Collective Works, and to reproduce the User Submission as incorporated in the Collective Works; 2) The PSF is granted a license to create and reproduce Derivative Works; 3) The PSF is granted a license to distribute copies or phonorecords of, display publicly, perform publicly, and perform publicly by means of a digital audio transmission the User Submission including as incorporated in Collective Works; and 4) The PSF is granted a license to distribute copies or phonorecords of, display publicly, perform publicly, and perform publicly by means of a digital audio transmission Derivative Works. - I, the Submitter, waive the exclusive right to collect, whether individually or via a performance-rights society, royalties for the public digital performance of the User Submission, subject to the compulsory license created by 17 U.S.C. Section 114 (or the equivalent in other jurisdictions). - I, the Submitter, specifically affirm the right to perform the User Submissions on the PSF's web sites or on other web sites designated by the PSF (including, but not necessarily limited to YouTube). - I, the Submitter, also hereby grant each person receiving the User Submission distributed by the PSF a non-exclusive license to access, use, display, and perform the User Submission in a non-commercial, private context.
