All oral presenters are requested to submit pre-recorded videos in the MP4 format in advance (35 min each for plenary talks, 25 min each for invited talks, and 12 min each for regular talks) to avoid unexpected technical issues. They are also requested to attend LIVE Q&A sessions (limited to 5 min each for the plenary and Invited talks, 3 min each for the regular talks) soon after their video presentations played back according to the conference program. Participants who will participate on-site can also give their talks in person.
All poster presentations will be given through on-demand videos pre-recorded in the MP4 format (8 min each), in a session named as “Poster session by on-demand videos”. In addition to the on-demand video presentations, on-site participants may also present their posters LIVE in a separate session named as “LIVE poster session”.
The presenters create their presentation files in ppt(x) format with narration and slide timing.
