We have opted for a format where each contributed presentation will take the form of a pre-recorded video, available during the original dates of the conference and on-demand after the conference concludes.

As a basis for the live programming, please be available and prepared for your live presentation and be ready to present and answer a live Q&A with attendees following your talk. We request a span pre-recorded version of your presentation in the case of technical difficulties.

We request you to prepare and upload a video of your presentation, consisting of a brief introduction with a webcam, if desired, followed by voice-over slides for your presentation. This will be posted within your presentation time slot on the ISCAS 2021 on-demand virtual platform. Please note that the file must be a video file in MP4 format (more details below).

Our recommended approach to record a compatible video from the content displayed on your computer screen and voice recording via the computer microphone is to record the presentation using Zoom, available to users on most platforms and in most countries. (in this method, you can show your face via webcam (if you’d like).)

Instructions for recording your presentation

  • Zoom

For Authors located in China who are unable to access Zoom for free, we recommend using the free software OBS(, which allows also to capture simultaneously yourself while speaking and your slides.
