TECHNICAL REQUIREMENTS
All video submissions at CHI PLAY 2024 need to adhere to the following technical requirements. Please note that videos that do not adhere to these guidelines may not be processed, and may not appear in the ACM DL or SIGCHI YouTube channel. It is your responsibility to ensure these requirements are met.
- Resolution is 1080p (i.e., 1920 x 1080).
- Encoded as an MP4 using the H.264 codec.
- Subtitles file in .srt or .sbv format.
There are no limitations on the video editor tools used. Authors are free to use whatever video editing tools, as long as all video requirements are met. Authors looking for a video editing tool can consider open-sourced and free options, e.g., Kdenlive.
VIDEO LENGTH
The video length limit for each track is as follows:
- Full Papers: 8 minutes
- Work in Progress: 3 minutes
- Perspectives on Play: 3 minutes
- Student Game Design Competition: 3 minutes
- Interactivity: 3 minutes
- Doctoral Consortium: 3 minutes
ENCODING TO MPEG-4/H.264 (.mp4)
Videos should use MPEG-4 encoding using the H.264 codec (file format .mp4). The open source video transcoder Handbrake provides good compression results and is available for OSX, Windows, and Ubuntu.
SUBTITLES
All pre-recorded videos must be submitted with subtitles. Do not encode captions directly within the video. Submit a separate subtitle file in .srt or .sbv format. Subtitles can be created automatically, for instance, using YouTube which provides free tools for generating subtitles. Additional step-by-step guidance by SIGCHI on using YouTube Studio and otter.ai is available here. If you use automatic services please make sure to review the generated subtitles and correct any errors. Please make sure that also any sound essential for following the content of the video is described in the subtitles. Information on how to describe non-speech information can, for example, be found at this website. If you have questions regarding subtitles, please contact our CHI PLAY 2024 Accessibility Chairs (a11y@chiplay.acm.org).
ACCESSIBILITY CONSIDERATIONS
In addition to providing subtitles, use the tips for creating an accessible presentation in this 5 minute video. Remember that some people will not be able to see your slides, so the presentation should be understandable from the script alone. This means adding sufficient verbal explanations in the script for the content on each slide, including any image, visualization and video. Make sure that the colors used in videos have sufficient contrast and are easily readable. Do not use colors as the only way to convey information and try to ensure that colors are sufficiently distinguishable. Mind the size of the text in your videos so that they can be read by everyone comfortably. We recommend the use of large font sizes: 36-point or larger for title slides and 24-point or larger for main body texts, and the use of accessible fonts, such as Tahoma, Calibri, Helvetica, Arial, Verdana, and Times New Roman.
Please avoid using flickering, flashing, or loud effects in your video. For example, flashing lights can induce seizures for people with photosensitive epilepsy. Avoid using fast-paced animations (simple appear/disappear is ok), unsteady camera work, flashing strobe lights, loud sounds, or repetitive alarms. If you include components, such as police car lights and sirens, consider warning viewers at the start of the video or right before the content so they can look away or mute their computers. The Trace Center offers an analysis tool to help authors assess whether their video is safe for people with photosensitive epilepsy (https://trace.umd.edu/peat/).
METADATA
For submission to an anonymized venue, all metadata that could identify the authors should be removed. For non-anonymized venues or camera-ready versions, please remember to review the metadata properties of your digital file and insert appropriate identifying comments at the submission time: author name(s), title, and copyright information.
THIRD-PARTY MATERIAL AND COPYRIGHT
Authors retain copyright to videos, but ACM requires that you sign an agreement allowing ACM to distribute the material.
It is very important that you have the rights to use all the material that is contained in your submission, including music, video, images, etc. Attaining permissions to use video, audio, or pictures of identifiable people or proprietary content rests with the author, not the ACM or the CHI conference. You are encouraged to use Creative Commons content, for example music available at ccMixter or Newgrounds. If you need to use copyrighted protected work, you are required to review and comply with ACM’s Copyright and Permission Policy and ACM’s Requirements about 3rd party material. In addition, YouTube’s copyright education website provides useful information on reusing 3rd party material.
THE USE OF GENERATIVE AI
All authors should be aware of the ACM Policy on Authorship, which articulates the authorised use of generative AI in submitted works. In particular, it notes that the use of generative AI tools (such as ChatGPT) is permitted, but all authors are responsible for the content created by these tools, the use of the tools must be disclosed. As such, authors are responsible for plagiarism, misrepresentation, fabrication or falsification of content through the use of generative AI tools, and could be sanctioned with penalties. Particularly, if such tools were used to create any part of the video, these uses must be disclosed in the video itself.
VIDEO PRESENTATION SUBMISSION PROCESS
Video presentations should be submitted on PCS. Please note that video figures are not the same as video presentations. PCS has a file size limit of 300 MB. If your video exceeds 300 MB, please upload a document with a link to your video instead.
USEFUL DESIGN RESOURCES
Authors can download design resources that might be helpful when preparing video presentations via this link, including the conference logo, background, and color palette.
