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. + +### 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 2022 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 ${TOPIC}." + + +Please **upload your prerecording(s) (and script/notes if any) via FTP** to the FTP server we have set up with the following details: + +- host: ftp-upload.emacsconf.org +- username: anonymous +- port: 21 +- folder: upload-here + +To upload your recording and any accompanying material to the above +FTP server, you can use your FTP client of choice. For instance, +FileZilla, a free/libre user-friendly application with a graphical +user interface. On deb-based GNU/Linux distributions such as Trisquel +you can install FileZilla by running `sudo apt install filezilla` in a +terminal. Otherwise, you can download FileZilla from their [project +website](https://filezilla-project.org/). + +You can also use a command-line interface with `ftp`: + +``` +$ ftp ftp-upload.emacsconf.org 21 +> anonymous +> passive +> cd upload-here +> send /local/path/to/file.ext file.ext # Don't forget the 2nd arg! +# Ctrl-D to exit +``` + +If you get a `500 Illegal PORT command.` command, try `passive` or +`quote pasv` to switch to passive mode before sending your file. + +If connection fails on the first try, please check to make sure the +details are exactly as described above; and if the issue persists, +please email so we can look into it. + +If you have a script or notes for your talk, please include it as well +so that we could use it to help us with the captioning of your talk. +You can also send us additional information to include on the wiki +page for your talk, such as a PDF or links to other pages or +additional videos. If you need help, please email +. + +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) or higher, in the +WebM format if possible.* + +> The conference broadcast will most likely 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 arrive in, +> the easier it will be to process and upload them. + +# Compression + +If you would like to compress your video before uploading, the following shell script may be useful: + + Q=32 + ffmpeg -y -i "$1" -c:v libvpx-vp9 -b:v 0 -crf $Q -aq-mode 2 -an -tile-columns 0 -tile-rows 0 -frame-parallel 0 -cpu-used 8 -auto-alt-ref 1 -lag-in-frames 25 -g 240 -pass 1 -f webm -threads 8 /dev/null && + ffmpeg -y -i "$1" -c:v libvpx-vp9 -b:v 0 -crf $Q -c:a copy -tile-columns 2 -tile-rows 2 -frame-parallel 0 -cpu-used -5 -auto-alt-ref 1 -lag-in-frames 25 -pass 2 -g 240 -threads 8 "$2" + +If you put it in a file called `compress-video.sh`, you can execute it +from the command line with something like `sh compress-video.sh +input-file.webm output-file.webm`. It will compress the file in two +passes. During the first pass, the frame count will increase, but the +speed will be 0. After the first pass, it will display proper progress +information. + + +# Tech-check + +We ask that speakers who plan to participate in live Q&A sessions schedule +a short tech-check in the weeks leading to the conference; this is to ensure +that you can perform all the common tasks you'd need such as sharing your +screen or toggling your microphone. + +We use BigBlueButton for our video-conferencing needs, and a quick way to +familiarize yourself with it is to run it in a test-room: + + +If this is your first time at EmacsConf or if you run into any problems, +please get in touch with us and we'll sort things out together! In those +cases, since we'll need to schedule a 1-on-1 tech-check with you, we ask that +you email the closest volunteer to your timezone in the list below (or zaeph +if none of the timezones is a good fit). You can also visit us at +[#emacsconf-org on Libera](irc://libera.chat/#emacsconf-org). + +We will likely schedule those 1-on-1 tech-checks with you on Saturdays or +Sundays, but we would be happy to try and work out another time if that +doesn't work for you. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+ +If you'd like to help out with the tech-checks, feel free to add your name and +email to the above list and email <zaeph@zaeph.net> to plan the logistics. + +Thank you so much for helping with EmacsConf 2022! + +# Frequently-asked questions + +## Can I present live? + +Tech issues kept happening during EmacsConf 2020, so we'd really +prefer that all talks have prerecorded videos. There might be time +for live questions and answers over a web conference, though, so if +you can record a short video covering your main points, you might be +able to go into more detail in live Q&A. + +## I have so much I want to share. Can I record a longer video? + +The conference program has so many interesting talks. We wish we +could fit everything in at full length! (Maybe EmacsConf month?) +Please think of your video as a short teaser that can get people +interested and point them to where they can find out more. You can +email links and other notes to add to the +wiki page for your talk. If you'd like to record a longer video *in +addition* to the short one for the main conference, please feel free +to send us that too. + +## I can't figure out how to record the video. Can I just present the talk? + +We might be able to help you record your talk using the BigBlueButton +web conferencing system before November 7. Please email + with some times that might work for you and +we'll see if a volunteer can meet up with you to record it. + +## How do I show my keystrokes on screen? + +In Emacs, you can use +[interaction-log.el](https://github.com/michael-heerdegen/interaction-log.el) +(in MELPA) to display the keystrokes and the commands they run in a separate +buffer. For a system-wide solution, you can look into +[screenkey](https://gitlab.com/screenkey/screenkey). + +## I'm not used to talking to myself. Can I present the talk to someone? + +We might be able to help you record your talk using the BigBlueButton +web conferencing system before November 7. Please email + with some times that might work for you and +we'll see if a volunteer can meet up with you to record it. + +## Can I see the other proposed talks? + +Once we've emailed all the speakers about their acceptance, we'll put +up the talk wiki pages. That way, you can see what else is going on +in the conference and maybe coordinate with other speakers in order to +minimize overlap and maximize awesomeness. + +## What if there are lots of great questions during Q&A and we run out of time? + +You can continue answering questions on the collaborative pad or IRC, +and we'll copy questions and answers onto the wiki page +afterwards. You can also answer questions on the wiki page even after the event. + +An extended live demo or Q&A session might be possible if someone +volunteers to broadcast it on an alternative stream. If you or a +volunteer is interested in helping with this, please feel free to +contact us at . + +## More questions? + +Please email . We'd love to hear from you. + +Thanks for contributing to EmacsConf 2022! + + + + + + + + + + + + -- cgit v1.2.3
