CHI Live and Recorded Video Policy

This document details the ACM SIGCHI policy for the CHI conference series. This policy is to be understood with respect to the overall ACM SIGCHI “SIGCHI Live and Recorded Video Policy”. 

  • Effective Date: November 19, 2019

It is the goal of the CHI Steering Committee to make CHI sessions available through live and recorded video whenever practical and possible. This policy defines the steps CHI conference chairs must take to support such video availability, the discretion conference chairs in the technical and business implementation, and expectations of attendee behavior as it relates to video capture. It also defines live and recorded video as a “best-effort” service that may have gaps, outages, and other limitations.

Video recording and streaming extends the reach of the CHI conference. No longer just a few days, in one place, CHI now has a global reach, 365 days of the year. The aim of this policy is to recognise that video is an essential means to share content from many of the venues at the CHI conference. 

However, some venues, such as interactivity, do not easily lend themselves to video capture and live broadcast and should be considered outside the scope of this policy. This policy applies to venues where fixed or mobile recording equipment can be used for the duration of the conference. The CHI steering committee aims to make as many conference venues and tracks available from live streams and recorded for later viewing. 

However, where local laws and costs make this impossible or prohibitively expensive the General Chairs of the conference in question need to raise this with the steering committee at least one year in advance of the conference. 

It is essential that any live streams should contain regular inclusion of the CHI conference logo and conference URL, along with SIGCHI and ACM logos and contain a copyright statement at the start and end of the stream, and have a copyright statement within the meta-data for the stream broadcast itself (where feasible). 


  1. Paper presentations at CHI conferences
  2. Keynote/Plenary/Award talks at CHI conferences
  3. Videos of Courses at CHI conferences
  4. Videos of Panels at CHI conferences
  5. CHI Video Showcase Submissions posted externally
  6. Other material recorded at CHI conferences (e.g., interviews)


  1. Supplementary Videos – (e.g., Video Figures submitted with CHI Submissions)
  2. Video Previews – (e.g., mandatory videos supplied with CHI paper final submissions)
  3. Interactivity Submission Videos (e.g., videos submitted as companions to CHI Interactivity submissions)


For Onsite Delegates

  • The registration process for onsite delegates must inform people that if they ask questions during a session this audio will be streamed and recorded. Those wishing to ask a question but not be recorded, can pass their questions to the session chair to ask on their behalf. 
  • Anyone attending a CHI conference (on-site) must use headphones when accessing any audio including streaming audio from video streams to avoid creating undue noise burdens upon other delegates. 

For Remote Delegates

  • Remote delegates attending a SIGCHI Chapter event, who are accessing a stream, are allowed to show this for audiences of up to 100 people. Events beyond this number of people require permission from the CHI steering committee. 
  • Remote delegates accessing a free stream are allowed to display this in a public or private venue  for audiences of up to 50 people, as long as no fee is being charged to attend such a venue.


  • CHI is a volunteer led event, which changes venue from year to year. Video streaming consumes large amounts of system or network resources and the ability to predict usage means that no quality of service guarantees are promised.  
  • The general chairs for the CHI conference can decide to make available varying quality streams to view.  


  • The costs of renting or borrowing SIGCHI equipment is borne by the CHI conference. Further, if recorded video is being published then it will be captioned and the cost of this captioning is borne by the CHI conference budget. Finally, we expect the CHI conference general chairs to provide one complimentary SV registration per video recording unit where video is used. The video/streaming chair shall nominate and recommend suitable candidates for the general chairs to appoint. (Suitable candidates will, for example, be experienced in video and the video/streaming chairs are expected to train all volunteers appropriately).
  • From practical guidance on equipment, please see section (1) of the CHI video guidelines 


  • Where the following venues exist within a particular year of the CHI conference then the CHI steering committee expects all paper presentations (delivered as a talk), Keynote/Plenary/Award talks, Panels, alt.chi talks, and case study talks to be streamed and recorded.  


  • CHI is pre-approved by the SIGCHI EC to stream, with varying quality levels. 
  • Until notified otherwise the SIGCHI VP for conferences and the SIGCHI VP for operations will understand all future CHI conferences will offer streaming.
  • CHI will always allow presenters the option to opt out of being included in any recording and live streaming. 


  • Videos must include the CHI logo for a particular year, the ACM and SIGCHI brands. It’s essential that any videos posted both inside and outside the ACM Digital Library (DL) are branded by SIGCHI and ACM, and contain a full screen CHI conference logo for no less than 2 seconds duration and a copyright statement.
  • From practical guidance on logos, please see section (3) of the CHI video guidelines 
  • Videos posted outside the ACM DL should be added to the SIGCHI YouTube channel.
  • Only videos with closed-captioning will be added to the ACM SIGCHI YouTube channel.
    From practical guidance on closed-captioning, please see section (4) of the CHI video guidelines


  • CHI will appoint a video/streaming chairs. The video/steaming chair handles organisation of equipment, training SVs, post-processing of recordings and final upload. 


  • Recording and Streaming of Paper sessions should aim to make use of the same type of equipment to ensure a consistent experience across sessions. Keynote/Plenary/Award talks, panels, alt.chi talks, and case study talks can make use of different quality equipment where available.
  • From practical guidance on equipment, please see section (1) of the CHI video guidelines (under development).  


  • Permissions are acquired when authors complete the ACM copyright form for their paper. And we remind the CHI organisers that our practice is to allow presenters the option to opt-out. For other formats (e.g., keynotes), permissions are acquired individually on-site. Presenters can choose after the presentation that their recording should not be uploaded (In this case, the material will be deleted). Where video was streamed live and permission was in place at the time then no request to revoke permission after the event is possible.


  • For recording only: A Copyright release form must be submitted to the ACM. This can either happen through the normal papers submission process, or be signed at the conference.
  • For Streaming: A Copyright release form must be submitted to the ACM. This happens through the normal papers submission process. However, a presenter may wish to opt out of live streaming. This could be communicated in the call for papers and any advertisement for live streams for the conference.
  • For Streaming: The description of the stream and the welcome image used prior to the stream starting or while paused should contain the copyright notice, e.g., “Copyright (C) 2021 ACM, Inc.”. This is included in the video bumpers provided by SIGCHI.
  • Videos to be posted need to contain the copyright notice, e.g., “Copyright (C) 2021 ACM, Inc.”. This is included in the video bumpers provided by SIGCHI.


  • Videos will be branded for CHI and ACM and SIGCHI. Ideally this would be through the use of video bumpers provided by SIGCHI. These can be acquired through the SIGCHI Operations team and prepended to the video prior to uploading. In addition, the CHI conference must provide a conference-specific video bumpers to supplement the SIGCHI and ACM bumpers. As videos can be easily downloaded and shared, SIGCHI require all videos to have the addition of branding (e.g. video bumpers) even if they are only going into the ACM DL.Please refer to the ACM SIGCHI SIGCHI Live and Recorded Video Policy for details of uploading, ACM policy and checklist.
