+
+I am an associate professor of biochemistry at the University of
+Oklahoma Health Sciences Center. I use X-ray crystallography to study

+voice control is a great way to create prose and write literate
+programming documents while maintaining one's health.

+# Responsibilities
+
+- Write captions or edit auto-generated captions in order to make
+  pre-recorded videos easier to understand
+- (optional) Note chapter markers
+- (optional) Note other things that may need additional help to make
+  them accessible, such as images not described in the speaker's
+  voiceover
+- (optional) Help extract information from Q&A videos after the conference
+
+# Preparation
+
+We'll set up a protected directory so you can get a sneak peek at the
+prerecorded videos, and we'll e-mail you the username and password to
+use. If slides, scripts, or auto-generated captions are available as a
+starting point, we'll upload those as well.
+
+# Process
+
+We'll e-mail all the captioning volunteers once speakers submit videos. 
+
+When you want to caption a video, browse through the protected
+directory to see which ones are available for captioning. E-mail
+<sacha@sachachua.com> or send a message to `sachac` via IRC
+(`#emacsconf-org` on IRC) so that we can reserve that one for you.
+Check out these [[captioning]] tips and fire up your favorite subtitle
+editor.
+
+We find that captioning generally takes between 2-6x the video time if
+you're an experienced captioner editing auto-generated captions, and
+can take a bit longer than that if you're starting out or starting
+from scratch. You can work with timestamps, or you can send us plain
+text and we'll get them aligned with the videos. It's okay to work in
+small chunks.
+
+E-mail your partial or finished captions to <sacha@sachachua.com> .
+When you're finished, we'll send them to the speaker for review and
+prepare the transcript for inclusion in the wiki.
+
+When the streamer shows the pre-recorded video, your captions will be
+included below it. They will also be combined into a transcript for
+the wiki, which will be published when the talk is live. Chapter
+markers will be listed below videos so that people can jump to
+specific sections.
+
+# After the conference
+
+If any talks weren't captioned by the time of the conference, you're certainly welcome to help caption them afterwards. We'll also extract the Q&A sessions and work on either chapter markers (to indicate when specific questions were answered) or captions for those.
+
+Here's what people said about how most of the EmacsConf 2021 talks were streamed with captions during the conference itself:
+
+- "I really appreciate the approach of doing things prerecorded and having captions."
+- "The captions for this conference have has an impressive amount of work put into them."
+- "++ to all that stuff. Great job on the captions, and the demonstrated functionality is very impressive."
+- "At first, I thought the captions would be unnecessary, but over time, understanding the accents for various individuals has been challenging, so the captions helped."
+
+Your captions will not only make talks more accessible during the conference, but also more searchable and more browsable after the conference. Thank you!

+- Follow up with speakers who haven't checked in yet
+- Check on speakers periodically so that they're not waiting alone

+
+Live Q&A is part of what makes EmacsConf better than a video playlist
+watch party. You can help speakers get settled in and feel at ease so
+that they're ready to go live as soon as their video finishes.
+
+# Preparation
+
+You'll need an account on bbb.emacsverse.org, and we'll set you up
+with moderator access on the relevant BBB rooms.
+
+We'll share a list of talks for your shift with:
+
+- starting time
+- talk title
+- track
+- speaker name
+- pronunciation
+- pronouns
+- BBB room URL
+- pad URL
+- email address
+- emergency contact information
+
+# Process
+
+## Looking for speakers
+
+We'll ask speakers to check into `#emacsconf-org` at least 30 minutes
+before their Q&A session and say something like "Hello, this is NAME
+checking in." You can hang out in the #emacsconf-org channel and keep
+an eye out for their messages.
+
+## Checking speakers in
+
+When you notice a speaker checking in, you can use something like
+`/msg NICK Hi, let me help you get checked in. Please join BBB_URL .`
+to send a private message to the speaker with the Big Blue Button URL.
+
+Join the BBB room. If you do not have moderator access, let sachac know.
+
+The BBB rooms will be set up so that people can join without approval.
+When the speaker arrives, you can take a few moments to say hi to
+them, thank them for presenting at EmacsConf, etc.
+
+Click on their name and choose **Promote to moderator.** 
+
+Click on their name again and choose **Make presenter.**
+
+**Checklist with notes:**
+
+- Can you speak and be heard? Is there echo?
+  - Help them doublecheck their audio quality. Using earphones or headphones can help avoid audio feedback, and using an external microphone can improve audio as well.
+- Can you hear me?
+- Can you share your screen? Will the screen be readable at 1920x720?
+  - Speakers may want to share their screen during the Q&A session. They can do so using the monitor icon in the lower middle. Sharing a single window is usually more advisable than sharing the entire screen, since it allows them to resize the window so that it's easy for people to read.
+  - We recommend good contrast with dark foreground on light background to make it easier for people to see things even in bright light.
+- If you plan to show your keystrokes, is that display visible?
+- If you want to share your webcam (optional), can you enable it? Is it visible? Will there likely be distractions in the background?
+  - The speaker's webcam is optional but highly recommended. The speaker can turn their webcam on using the camera icon in the lower middle.
+- Can you view the collaborative pad? Will you be comfortable reviewing questions on your own (perhaps by keeping it open beside your shared window), or will you need a volunteer to relay questions to you?
+  - If the speaker wants to read questions as they come in on Etherpad or IRC, help them load the pad or the track-specific IRC channel. If there is a host for the session, the host can also read questions out loud. Let the speaker know that they can answer questions in any order they want, skip questions, take a little time to think about their answers, and answer questions for as short or as long as they'd like. The room is dedicated for their use, so they don't have to worry about stepping on someone else's Q&A. The first part of their Q&A will be streamed. The host will let them know when the time for streamed Q&A is almost done, but people can continue discussing things in the Q&A room if they want.
+- If you plan to play sounds during your Q&A session, is that audible?
+  - Sometimes speakers will need to set up a virtual loopback device to get their system audio to be included in BBB. This is somewhat complicated and should be tested before the conference.
+  
+Once the speaker is settled in, you can let `#emacsconf-org` know that
+the speaker has been checked in.
+
+Let the speaker know how many minutes before their Q&A starts. They
+can take a break before then. Many speakers choose to watch other
+talks before theirs.
+
+## Heads-up before the Q&A starts
+
+Check in on the speaker about five minutes before their Q&A session
+starts to give them a heads-up. Ask them to close any other tabs that
+they might be using to watch EmacsConf, because that will create an
+audio feedback loop once their Q&A session is being streamed.
+
+Right before the Q&A starts, make sure the host has started the
+recording. If there is no host or the host has forgotten, you can use
+the **Start recording** button at the top.
+
+In between checking in people, feel free to enjoy the conference!
+
+## What if a live Q&A session is starting within 30 minutes and the speaker hasn't shown up yet?
+
+Let us know on `#emacsconf-org`. You or another organizer can contact
+them using their emergency contact info. If you prefer to not use your
+phone, you can ask one of the organizers in #emacsconf-org and we'll
+call the speaker for you. 
+
+If the speaker is still not available, we can stream any ongoing Q&A
+sessions or open it up for community discussion.
+
+## After the Q&A wraps up
+
+If you notice that the Q&A in a room is all done, you can thank the
+speaker and click on **Stop recording** in the top middle.
+
+# After the conference
+
+Checking in speakers goes a long way to reducing the technical risks
+and keeping the conference running smoothly. A smooth checkin can
+encourage both speakers and participants to come back next year for
+more Emacs awesomeness. Thank you!

+# Responsibilities
+
+For talks with live Q&A sessions:
+
+- Start the recording
+- Ask the speaker questions from the pad and read out feedback if you want
+- (optional) Monitor IRC for questions as well
+- (optional) Let the other organizers know when you're ready for conference
+  participants to join the Q&A; moderate the discussion as needed
+- Handle technical issues that turn up
+- Give the speaker time warnings
+- Keep things cool
+
+Many speakers find it easier to reply to questions that are spoken
+aloud, and this also ensures that the questions get into the
+recording. As the host, you can help shape the Q&A session by choosing
+the order of questions to ask (unless the speaker wants to address a
+different question). You can also help rephrase unclear questions or
+help the speaker feel more comfortable by reminding them that they
+don't have to answer all the questions.
+
+# Preparation
+
+We will give you a list of talks with the times, speaker info, pad
+URL, and URL for the live Q&A session. Please keep the Q&A URLs secret
+until you are ready for everyone to join the Q&A session.
+
+We will also add you as a moderator to the rooms for the talks in your
+shift. You may want to practice muting people in BBB.
+
+We strongly recommend using a headset or earphones to minimize audio
+feedback. Using a headset microphone or an external microphone can
+also improve your sound quality.
+
+# Process
+
+This year we are experimenting with per-talk pads in order to simplify
+the experience for the speakers, since many speakers found it
+difficult to find and focus on their section in a long pad.
+
+At least 5 minutes before the Q&A session starts, go to the provided
+URL. If BBB shows you a list of meetings, you can click on **Join**
+to join the selected one. If you do not have moderator access, let
+us know in `#emacsconf-org` and we can add you.
+
+Have another window for the pad for the current talk. 
+
+Have another window or two for IRC. You may want to set up your
+windows so that you can quickly glance at #emacsconf-org. Optionally,
+you can also monitor the chat channel for your track (optional).
+Ideally, an IRC volunteer will monitor that channel and copy the
+questions into the pad for you, so you can focus on just the pad if
+you like.
+
+Make sure you do **not** have another window watching the stream, or
+you may get audio feedback whenever you unmute yourself. If you notice
+audio feedback when other people unmute, you can ask them to make sure
+they aren't watching the stream in a different window and that they
+haven't accidentally joined twice.
+
+To minimize background noise, keep your mic on mute unless you're
+speaking. You can optionally turn on your webcam.
+
+The streamer will join the BBB meeting shortly after the prerecorded
+video ends. When the streamer gives you the go-ahead, **turn on
+recording** and confirm that it is on. Double-check that recording is
+on by seeing whether the button at the top has changed to a red button
+with a timer.
+
+The Q&A will start out closed; just you and the speaker. Depending on
+your comfort level and how the discussion goes, you can let us know
+when you would like it to be opened up to general participation by
+inviting people out loud (and possibly quickly posting in #emacsconf-org). 
+Then we will update the public BBB redirect URL to
+point to the BBB room so that people can join. This should take less
+than a minute to update. People will then be able to join using the
+Q&A URL that will be in the talk page and in IRC. That way,
+participants can join the Q&A session and ask directly. You can then
+shift to be more of a moderator, reminding people to stay on mute
+unless it's their turn to speak and muting people as needed.
+
+BBB sometimes has issues if there are lots of participants with
+webcams on. If you notice that things are getting slow or choppy, you
+can ask participants to turn their webcams off.
+
+Please give the speaker a 5-minute warning and a 2-minute warning
+before the end of their streamed Q&A session. If you've decided to
+open up the Q&A session, it can continue off-stream for as long as the
+speaker likes while you move on to the next Q&A session to host. If
+the speaker would like to wrap up, they can leave the meeting whenever
+they want. You can then thank everyone and move on to the next
+presentation.
+
+# In case of...
+
+- Incidents: If someone isn't keeping the
+  [[guidelines for conduct|conduct]] in mind, you can moderate using
+  BBB's tools (muting or removing participants), or let us know in
+  `#emacsconf-org` and we'll figure out how to deal with the
+  situation.
+
+# Afterwards
+
+Q&A sessions are what make EmacsConf more fun than a playlist. =)
+Thanks for helping make EmacsConf awesome!

+# Preparation
+
+If you'd like to announce talks and Q&A sessions, we can share a pad

+## Copying questions
+
+Open `#emacsconf-gen` and/or `#emacsconf-dev` depending on your shift
+and your ability to keep track of multiple things at the same time.
+
+In another window, open the Etherpad for the relevant talk(s). You can
+find pad URLs on the talk page or in the talk announcement that is

+
+When you notice a question posted in IRC, reply to the person and say
+that you'll copy the question into the relevant pad. If you're using
+ERC or another programmable IRC client, you may want to make a command
+that simplifies that process.
+
+Copy the question to the bottom of the question list of the relevant
+pad and add the person's nick after it in parentheses. Please keep it
+as a top-level item instead of nesting it under something else. You
+can reword the question for clarity if needed.
+
+The conversation might be too fast to keep track of, especially if the
+channel for a track has overlapping discussions. Feel free to ask if
+people have any more questions for a particular speaker. You can also
+encourage people to use conventions like starting their questions with
+Q: or Q-talkid:.

+
+If you would like to continue scribing the live Q&A for a session even

+for the live Q&A. Scribing live Q&A sessions might be more useful than
+scribing the pre-recorded video portion because people will have
+access to the videos and possibly transcripts, while Q&A may take a
+while to extract. 
+
+To make it easier for the hosts and speakers, we keep the BBB room
+URLs secret until the hosts or speakers give the OK to open it up.
+When the host or speaker invites everyone in, you can add the BBB URL

+
+1. ssh orga@res.emacsconf.org
+2. `emacsclient -c -nw emacsconf-2022-private/conf.org`   (or `emacs emacsconf-2022-private/conf.org` if there's no server yet)
+3. `M-x emacsconf-add-org-after-todo-state-change-hook` unless you've already done so this session
+
+Play talk:
+
+1. Use `M-g t` (`emacsconf-go-to-talk`) to find the talk, or use another way to navigate to the talk heading. (Org agenda?)
+2. Use `C-c C-t` (`org-todo`) to mark the talk as `m` (PLAYING - *m*pv).
+
+This should make MPV appear. If it does not appear, you can manually
+play it with one of the backup plans below:
+
+### Backup plan: emacsconf-stream-play-video from conf.org
+
+1. Use `M-x emacsconf-stream-set-talk-info` to update the overlay. If
+this does not update the overlay, play the video and then manually
+copy the right overlays over `~/video.png` and `~/other.png`.
+
+2. Use `M-x emacsconf-stream-play-video` to play the video for the talk.
+
+### Backup plan: Use track-mpv
+
+1. ssh emacsconf-$TRACK@res.emacsconf.org
+2. cd /data/emacsconf/cache
+3. ~/bin/track-mpv file-to-play.webm
+
+This should make the file play in the correct display. 
+
+## Updating the overlay
+
+If the overlay wasn't automatically updated by the todo state change
+hook in conf.org, you can set it from conf.org if you have access. Use
+`M-x emacsconf-stream-set-talk-info`. If that doesn't work, manually
+copy the right overlays over `~/video.png` and `~/other.png`. The
+overlays will be in `/data/emacsconf/overlays`.
+
+## Displaying an emergency announcement
+
+echo Your emergency announcement here > ~/news.txt
+
+Be sure to clear it with `echo > ~/news.txt` when done.
+
+From conf.org on res, you can also use `M-x
+emacsconf-stream-broadcast` to announce something on both streams or
+`M-x emacsconf-stream-set-news` to set the news on one stream.
