Video Presentation Instructions

Due: June 1, 2021

Presentation Guidelines

We are asking authors of papers and pictorials to prepare a pre-recorded video of their presentation. By using pre-recorded videos, we can minimize potential tech-related issues, ensure correct captioning, and provide a seamless transition between talks.

Summary

  1. Record your video using MP4, MKV, or AVI file formats.
  2. The video length is five (5) minutes for all papers and pictorials.
  3. Generate a subtitles file using the SRT format. Do not encode subtitles into the video. You will upload the subtitles as a separate file. This is important for accessibility.
  4. Submit your video and caption files to PCS.
  5. Attend the Session and Live Q&A. Following each pre-recorded talk, we will have a few minutes for live Q&A, and we ask that at least one author be present during the allocated time for questions. Please contact us if there is a conflict. The conference agenda with the schedule for each presentation will be shared soon.

Presentation Details

You can find detailed presentation information below.

Record Your Video

We recommend a full-screen presentation format for your content (slides, demos, etc.) with a picture-in-picture speaker view. Still, you are welcome to explore alternative formats that are engaging and allow the audience to see the speaker and the content. We suggest using a high-quality microphone and record with a minimally-distracting background for the best quality. “Busy” slides with patterns or small images can show compression artifacts when streaming.

Duration

The length of your video must be at most 5 minutes.

Software

There are a variety of software tools available for recording and editing your presentation. Complete commercial solutions include Camtasia and Screen flow, among others, but some free options include: Zoom, Open Broadcaster Software (OBS), and Wondershare Filmora.

Formats

Please record your video in a common file format such as .mp4 or .mkv.  The resolution should be 1080p or better for optimal streaming quality.

Generate a Corrected Subtitles File

We are asking each presenter to submit a video caption file (SRT file) along with the video itself. An SRT file or SubRip (.srt) file is a common type of raw closed caption format or subtitle format.  You should not encode captions onto your video, but we do ask presenters to manually review the separate SRT file and make any corrections to the captions before submitting.

You may use any means of generating an SRT file that you wish, but we strongly suggest following the instructions for using YouTube’s free service for automated transcriptions. The linked document was prepared by the CHI 2021 Accessibility Chairs team.

Submit Your Video and Captions File

Once you have your finished video and captions files, you will upload the files to PCS using camera-ready form for your submission in PCS. We will stream the videos during your session time at the conference and the videos will be added to the SIGCHI Youtube channel.

Prepare your Files

Name your finished video: PaperID#-PresenterLastName.mp4. 

Name your SRT caption file PaperID#-PresenterLastName.srt.

Suggestions for Preparing Your Presentation

When preparing your presentation video, please keep the following suggestions in mind:

  • Select a slide format that has high contrast and readable text.
  • Avoid busy patterns or images which can be difficult to read.
  • Use large text so that it is easy to read and displays well on some attendee’s devices.
  • Patterns and small text are prone to video compression artifacts and other distortions when the video is streamed.
  • People with Color Vision Deficiency (CVD) can have difficulties distinguishing between different colors in graphics and slides. There are resources online you can use to improve your color combinations: Coblis — Color Blindness Simulator.
  • Organize your content to be clear and approachable to everyone.
  • Instead of relying on equations or detailed definitions, you can connect better with your audience through real-world examples.
  • Explain your approach in the context of the questions you are trying to answer.
  • When explaining results, focus on how they tie back to your original questions.
  • Add images, demonstrations, and other illustrative tools where appropriate.
  • Limit bulleted lists to no more than five bullets and avoid cluttering your slides with text.
  • Be selective with visuals and ensure that all images have descriptive text for increased accessibility.
  • Since you are creating and editing the final video, you can easily include system demos or animations directly within the presentation.
  • Consider creating a script and designing your presentation with captioning in mind: minimize how much content you place on the lower third of your slides to improve the readability when the captioning is added.
