Due to the rapid worldwide spread of new coronavirus infections, each specialized conference in the OPIC 2020 decided to operate in the following adjusted scheme. Please check carefully the scheme of the conference where you will attend. More detailed explanation will be available in the website of each conference.

In the following description, “presentation video” means the file that is produced from Power Point by yourself and uploaded to the conference website (https://opicon.jp/video-submission) before the submission deadline 7th April, 2020. You use Power Point to record a presentation talk at a preset slide-show timing in your PC. Then you convert the file to a video file in mp4 by export command of Power Point. Before uploading, please check the quality of voice and slide-show timing. We recommend to use a separate microphone rather than a PC microphone. Accepted speakers who submitted for “poster presentation only” are also requested to submit a presentation video the same as described above for oral presentations.
Please check also the specific conference where you will present a paper. The additional request may be set for your presentation video file.
　With a few exceptions, all presentation videos will be uploaded to YouTube and Youku at “unlisted” property during the week of OPIC2020 (during 9:00 of April 20 – 17:00 of April 24, Japan time). All registered participants will have access to all archives from the registration accounts page, including presentations at meetings other than the one they registered for (more on this later). However, these archives are protected from downloading.
　All registered participants can access the full abstracts of OPIC2020.
