Design details: For an article describing how consensus works at our medical meetings I am showing a timeline of the audience retention graph for a YouTube video annotated with image of speaker and then subjects addressed for presentation and then image and person name for the discussion (which is twice as long as presentation). See https://www.slideshare.net/ksolez/kim-solez-spirit-of-banff-embodied-in-i-ifta-discussion and https://www.youtube.com/watch?v=rpRJoMMsXvs . Show us how we can do further edits etc.
