Projects related to conferences and presentations are frequently easy to capture – depending on the number of speakers, yet provide awesome amounts of material to be moulded into a video-presentable form for the final product.
Speakers who use visual aids (powerpoint for example) expect those to be edited into the video. When the presentation is long, some cruel editing of the material might be required, along with some on-screen help as to where we are in the sequence; or graphic overlays to aid clarity of the subject.
In the above example (in French), an evening of presentation and Q&A time is divided into overview, details and responses to questions – by question. Here is the overview section of 15 minutes, the rest can be accessed through the same YouTube channel – all sections are public.
