The information you need to upload to YouTube will be found on the website:

DO NOT display your name in the video. The juror interface is designed so that your identifying information is not provided, only the video is shown. So do not worry about adjusting your screen name or profile.

Please note that it can take from 30 minutes to several hours to upload a video. How long it takes depends completely on the size of the video and the speed of your Internet connection. The larger the video, the longer the upload time will be.
