Formatting Guidelines for UbiComp/ISWC Supplemental Videos

This guide provides information for preparing a supplementary digital video for submission to the ACM Digital Library with your UbiComp/ISWC submission.

• Technical Requirements
  • Size
    • A submission that includes a supplementary digital video must not exceed 100 MB in total size (paper + video) for it to be included in the ACM Digital Library.
  • Format
    • We strongly suggest an MP4 encoding using the H.264 codec for your digital video submission. Most video editing software provides an exporting option to MP4/H.264, for example iMovie, Adobe Premiere, Camtasia, and Final Cut Pro. If you prefer to use free software, x264 can encode any video into H.264. The conference does not accept analog (videotape) submissions, software applications (.exe files), or digital video clips requiring a specific computing platform or additional software to play.
    • We strongly recommend 16:9 aspect ratio. Encode your video using square pixels for the pixel aspect ratio to avoid your movie looking stretched when projected.
  • Duration
    • Supplementary video figures do not have a specified limit for duration, although we recommend staying within 5 minutes. If you plan to play the figure during your conference presentation, be sure that you allow enough time both for the video and the other portions of the presentation, including time at the end for questions.
  • Identification
    • The camera ready version of your video submission should contain a title slide with the title, authors, and affiliations. Authors retain copyright of videos but ACM requires that you sign an agreement allowing ACM to distribute the material. This form is a part of the eform sent to you via email from ACM before you submit your camera-ready submission.
• Accessibility Guidelines
  • If possible, make captions available for your video in respect of any audio content provided.
    Ensure that text and illustratory content are clear, using San-Serif Fonts (e.g. Arial, Tahoma, Trebuchet). Please also ensure that red and green are not used together for diagrams and text, and aim to ensure as high a degree of contrast in relation to this content.
  • Try to ensure that your video complies with the standards for people with photosensitive epilepsy.
  • If your video does not comply with the aforementioned epilepsy standards, or contains content which could be offensive or upsetting, please provide a warning (written and oral) at the beginning of the video so that potential viewers have an option not to view this content.
  • Please provide audio descriptions of key visual content. This is to assist some people with visual impairments follow the narrative of your video.

This document has drawn heavily on the Guides for Submission written by previous CHI and CSCW video chairs, originally published on the CHI '99 Conference website, as well as material written by the UbiComp and ISWC Video Chairs 2014. Portions of the UIST video guide have also been used.
