Speakers: recording your talk

This page contains help for speakers recording their talk.

The online conference

As previously mentioned, the talks for 2020 will be pre-recorded and then broadcast during the conference dates. A few weeks after the conference, all recordings will be freely available.

If you are unavailable

Recording is quite different from speaking and doing so during a pandemic, even more so. If anyone is unable or would prefer not to record, just let me know. There is no down-side to withdrawing your talk. There is a lot going on with everyone. We are asking you to do far more than any previous conference. We understand this is a lot to ask of you. We thank you for your work and appreciate the effort this takes.

Tutorials

Tutorials by nature are different from talks. If you don't want to record the tutorial, we are fine with this.

When

We hope to have your recording by May 18 - this is not a hard deadline. If you can make it by then, great. The more recordings we get early, the more time the production crew has to prepare them for broadcast.

Schedule

The schedule will roughly follow the same format as in previous years:
  • talks are 45 minutes
  • 15 minute break after the talk
  • these are not hard limits
  • see Q&A below
We will publish the schedule about two weeks before the conference.

Question and Answer

There will be optional live Q & A session after your talk. Talks, including the Q&A session are 45 minutes. If you go over on the Q&A, that's OK, no big deal.

If you do not want to do a Q&A after your talk, that is OK. We do not expect everyone to be available, especially when it will be during your sleep time.

If you are not on the East Coast of North America, we will try to put your talk at a better time for your Q and A. We will send a separate email asking for your timezone information.

The questions will be submitted via IRC / Twitter / email. They will be collated by volunteers and provided to you. Please read the question before replying to it.

Questions will be audio only, probably via Skype. Or we can call you. Details will follow.

Uploading your talk

Feel free to use whatever storage you want. If you want to host your own download location, please send us the URL. Please upload the talk so we can download it via an un-autheticated URL. Our goal: we don't want to enter passwords or click Next to get the file. They will be downloaded and processed via a scripted process.

For whichever upload location you choose, please verify the file can be fetched from the command line (e.g. via fetch, wget, curl).

If you upload the video to Google Drive, Apple's iCloud, or Dropbox, the following will help you create a downloadable URL for our scripts.

Subject: BSDCan 2020 video

For recording

Please use whatever recording method you can get access to. For example, this should record the screen in X and should work on all OS:

ffmpeg -video_size 1920x1080 -async 1 -framerate 30 -f x11grab -i :0.0 -f oss -i /dev/dsp4 \
-c:a aac -f mp4 -pix_fmt yuv420p -c:v libx264 -b:v 2048k -preset ultrafast output.mp4
NOTES:
  • :0.0 can be different depending on which screen you want to record
  • /dev/dsp4 is which microphone to use
The OBS (Open Broadcaster Software) project is highly regarded. If you can use it, please do. If not, whatever you can use will be good. A few details about the recording:
  • recording file format: mkv/mp4
  • resolution: 1080p
  • length 25-40 minutes (very flexible - however long your talk takes)
  • the video needs to have the slides
  • if the video can also have your face, great, if not, also great
  • an external microphone can help, if you have one

Speaking without an audience is hard. Some have suggested a stuffed animal or similar on top of your webcam or on the wall can give you something to speak to.

Please do not be obsessed with getting the perfect video. When speaking live at BSDCan, you don't get a redo. There is no need to edit the video. That will be done by the production staff after you upload.

Please don't treat any of these as absolute-requirements. They are supplied to you only because we found them and thought they might help.
