Creating and providing your presentation for CHI Greece 2021 - Video recording instructions

  • Videos should be prepared using the SIGCHI video recording guidelines. The final video should have the following properties:
    • 16×9 aspect ratio
    • MP4/MP4V format
    • The Video Codec should be H.264 and the Audio Codec AAC+ or AAC. MPEG4 PART 10 or AVC
    • Preferably, use a Picture-in-Picture presentation format to show both presenter and slide content
  • Video recordings should be strictly within the allocated time limits:
    • Full papers: 15 minutes
    • Short papers: 10 minutes
  • Videos must have accompanying subtitles/captions to meet accessibility standards
    • Subtitles must be in the form of a separate SRT format file.
    • SRT subtitles files can be created manually, or using YouTube (by uploading the video privately and then downloading automatically generated subtitle file) or using Otter.AI. However, automatically generated subtitle files should be then manually edited, as automated tools often have issues with technical terminology.
  • You can upload your video recording and the subtitles through the CHI Greece 2021 platform using the Author Credentials that have been mailed to you.

Please email the Video Chairs with any questions about the video technical specifications: and
