Informations about presentations:

All technical sessions and plenary talks will happen through Zoom following the conference program.

We kindly ask all authors, session chairs and PC Members to create a personal Zoom account and download the Zoom client application (available for Windows, MacOS and Linux) since using Zoom from web browsers can pose some problems according to our experience.

In the next coming days, all of you will be receiving an email with the Zoom link to the virtual event. Please check your spam folder if you have not received it. If you have any problem, please get in touch (

Finally, we would like to emphasize that by joining the LARS/SBR Zoom sessions as a published work presenter, as a session chair, or as a PC Member, you agree with streaming and publishing all video content related to the Zoom presentations, including those with images of yourself, and also on Youtube channels streaming LARS live videos.

Instructions for video presentation:

In order to avoid presentation issues during the event it is imperative that you send us a video presentation, that will be used if you can't be there. In the last event, some authors also prefered to use the videos instead of live presenting so they could focus on answer questions or chat with the participants during the presentation.

To prepare you video presentation please follow these instructions:

Step 1) Prepare a video (MP4 H.264 1080p) of a maximum of 12 minutes with an overview of your work, summarizing the methodology and results. This video will be made available for all conference attendees.

IMPORTANT: Do not include in your videos any content that cannot be distributed (e.g., copyrighted photos or music from the internet). It is best not to use any background music. See below for the Technical details on the video file format.

Step 2) Upload your video to Jems in the "Video presentation" file input.

Step 3) Also upload and make your video available on YouTube, with a visibility of either Unlisted or Public. Be sure to mark your video as "No, it's not made for kids" and also "No, don't restrict my video to viewers over 18 only." Furthermore, under "Show More" in Details, please check the "Allow embedding" checkbox.

Step 4) Go to this form and fill-out the information of the presenting author that will be present during the live Q&A session.

Step 5) During the event, between Monday October 11th to 14th, at the time specified in the program, the presenting author must be available on the the online platform for the whole duration of the Workshop Q&A. The final program for LARS 2021 WTDR/CTDR is available here.
