Best Practices for Recording Videos

Plan the content

  • identify the story
    • demos: what problem is being newly solved? what impact can we expect from the proposed solution?
    • group updates: what is the group? what impact does it seek to have and is actually having on the Web?
  • make it accessible - follow the accessibility considerations when planning, scripting, storyboarding well before hitting the record button
  • plan for a short video - aim for 2 minutes if possible for a demo, 3 minutes for a group update
    • think of the demo as a teaser for a deeper technical dive, NOT the deep technical dive itself
    • if part of the process being demonstrated is slow or a bit long, plan on showing an abbreviated or accelerated version of the process
  • write up what you plan to say, keeping acronyms and jargon to a minimum, and explain it when using it
    • demos: show and tell - plan on describing orally what is happening in the demo
  • if you plan on showing code, prepare it so that it can be shown with a large font and clear contrasted colors, and focused on the most relevant code
  • if you plan on showing slides, see guidance on preparing them
  • end the script with indications on where to follow up for people interested in more details or in getting involved

Test your setup

  • ensure your audio setup is clear and crisp
  • if you plan on video-recording yourself speaking:
    • ensure your face will be well-lit, with the camera at eye level
    • ensure the background in front of which you'll record yourself is not distracting
    • memorize as much of your script as possible, or use a teleprompter to read your script while looking at the camera
    • if recording from a mobile device, record in landscape mode

Shooting the video

  • Speak clearly and slowly. No need to rush.
  • especially if reading from your script, make sure to keep your tone lively - imagine you're telling an exciting story to a colleague
  • if you're recording a screen, remove any distracting elements (irrelevant windows and tabs, notifications); if possible, zoom and highlight the most relevant elements
  • If you're video-recording yourself speaking, leave a few seconds before and after you start speaking in recording mode to allow for editing

Submitting the video

  • Once you're happy with the resulting video, please share it with using one of the on-line systems for sharing large files (e.g. Dropbox, WeTransfer, Google Drive, etc)
  • If you read from a script, please share it with us as it will help with captioning as well.
  • If you screen-recorded slides, please share them as well.
