Demo videos are uploaded to the official YouTube account: www.youtube.com/@OurBigBook
The video files together with the assets used to make them are also made available in the OurBigBook media repository under the video/ directory.
Video guidelines:
  • desktop recording area size: 700x700. This could perhaps be optimized, but this is a reasonable size that works both as an YouTube Short and Twitter post
    We've been happily using vokoscreenNG.
  • use Chromium/Chrome to record
  • resize window to fit recording area horizontally by using the Ctrl + Shift + C debugger view. Make sure to also resize the browser window vertically (cannot be done on debugger, needs resizing actual window) otherwise you won't be able to scroll if the page is not taller than the viewport.
  • music style guidelines: cool, beats, techno, mysterious, upbeat
    Some of the videos contain non-fully free YouTube music added via the YouTube UI. Reupload together with the video files appears however allowed. Ideally we should use fully CC BY-SA music, but it is quite hard to find good ones. NC is not acceptable.
  • hardcode subs in the video. No voice. We've been happily using Aegisub to create the subtitles in .ass format and ffmpeg to hardcode:
    ffmpeg -i raw.mkv -vf subtitles=sub.ass out.mkv
  • add the video as the first video of the "Videos" playlist: www.youtube.com/playlist?list=PLshTOzrBHLkZlpvTuBdphKLWwU7xBV6VF This list is needed because otherwise YouTube's stupid "Shorts" features produces two separate timelines by default, one for shorts and one for non-shorts. With this list, all videos can be seen easily as non-shorts.
