You can find the program of IJCB 2021 at . There is an “(L)” or “(S)” before a paper title to indicate whether  the presentation is a long oral presentation or a short one. We will have no poster presentations in IJCB 2021.

A long presentation will be 15 minutes long, followed by 5 minutes for Q&A. A short oral presentation will be 5 minutes long, followed by 5 minutes for Q&A. 

Since the conference is online and attendees are in different time zones, the authors will have to create and send the organzier a pre-recorded video of their presentation. Further, for the attendees to obtain a summary of your work, a 60-second highlight video is also needed. 

To facilitate this, the authors should kindly complete the following by July 23, 2021:

  1. Record a 60-second highlight video to introduce your work. 
  2. Record either a 15-minute presentation video for long oral papers or a 5-minute presentation video for short oral papers.
  3. Rename your 60-second highlight video as XXXX-highlight.mp4 (XXXX is your paper ID).
  4. Rename your presentation video as XXXX-15min.mp4 or XXXX-5min.mp4.
  5. The recommended resolution is 1920 × 1080, and the recommended file format is MP4. The maximum file size is 350MB.
  6. Upload them to CMT at  Author Console → Actions → Edit Camera Ready Submission → Files. Please remember to click the “Save changes” button after the two video files are uploaded. (Note: By the way, if you had uploaded a supplementary PDF file, please remove it before uploading the videos. The proceedings will only contain your camera ready paper.)
  7. In summary, there should be 3 files there: XXXX.pdf, XXXX-highlight.mp4 and XXXX-15min.mp4 (or XXXX-5min.mp4). You must not modify your XXXX.pdf file since the camera-ready file is already being processed for publication. The presentation videos will be played during the assigned sessions (more details below).
