[[!meta title="Notes and tips on preparing your talk"]] [[!meta copyright="Copyright © 2021 Amin Bandali"]] This page contains notes and tips for our speakers on preparing their talks and presentations. Please read through the list and consider it while preparing your talk. If you have any questions, concerns, or suggestions please feel free to write to one of the organizers directly (e.g. ), or write to one our organizational mailing lists: the public list, or the private list, depending on the nature of the matter you would like to discuss. Note: being part of a wiki, this page is subject to change (including by you!); so please check back every now and again for any changes and updates. [[!toc levels=4]] ### Guidelines for conduct Please review our [[guidelines for conduct|conduct]] when preparing your talk, to make sure we're all on the same page and strive to make the event a great experience for all. If you're not sure whether your talk or presentation style meets the guidelines laid out in the guidelines for conduct, we'd be happy to help. You can email Sacha Chua at to chat more about this. ### Recording your talk To help EmacsConf 2021 run smoothly, please prerecord your talk. and send us your video(s) by **November 7** at the latest (three weeks before the conference), to allow us enough time to do any needed processing (e.g. format or codec conversion) in preparation for the event. Please consider submitting a prerecording as early as possible so that we can see if volunteers can caption your video to make it more accessible and searchable. To make it easier for organizers and attendees to correctly pronounce your name, please start your video with something along the lines of: "Hi! I'm ${NAME} and I'll be talking about ${TOPIC}." Please **send your prerecording(s) via email to **, either in form of attachments (if reasonably small), or direct link(s) to download from elsewhere. If you have a script or notes, please include it as well so that we can use it to help us with captions. You can also send us additional information to include on the wiki page for your talk, such as links to other pages or additional videos. If you need help, please e-mail . To record your video, you could use any of the following pieces of free software, depending on your needs: - [OBS](//obsproject.com) - [SimpleScreenRecorder](//www.maartenbaert.be/simplescreenrecorder/) - [vokoscreenNG](//linuxecke.volkoh.de/vokoscreen/vokoscreen.html) - [peek](//github.com/phw/peek) - [ffmpeg](//trac.ffmpeg.org/wiki/Capture/Desktop) You might find the following free software programs useful for editing your video recordings: - [Kdenlive](//kdenlive.org/en/) - [Blender](//www.blender.org) - [Pitivi](http://www.pitivi.org) Per GNU Project's [Guide to Formats](//audio-video.gnu.org/docs/formatguide.html), we prefer to receive prerecorded videos in formats unencumbered by software patents, such as `video/webm` (WebM-encoded video files, with `.webm` file extension) and `video/ogg` (video files encoded with the Theora video codec, encapsulated in an Ogg transport layer, with `.ogg` or `.ogv` file extension). However, if for one reason or another you are unable to send us your prerecorded video in one of the above formats, you may submit them in other common formats, like MPEG-4 (`.mp4`), and we will try to convert them to our preferred formats on your behalf. *Prepare recorded video in 720p (1280px by 720px); WebM formatted if possible.* The conference broadcast will be in [720p](https://en.wikipedia.org/wiki/720p) (1280px x 720px, progressive) using the [Webm](https://www.webmproject.org/) video format. The closer to this format submitted video files arrives in, the easier it will be to post. After you send in your video, if you've indicated that you'd like to do live Q&A, we'll set up a tech-check call with you. We'll post details here closer to that time. Thank you so much for helping with EmacsConf 2021!
