Réalisateur d'enquête

Make a 90-second 16:9 visual investigation answering [one question about a historical event] from its primary records: each record on screen tagged with its page, the words that matter highlighted as they are said, a clock, evidence that fails set aside with the reason, what was recorded kept apart from what was inferred, and the sources on the last frame for [who will watch, e.g. people who have heard the story but not the record]. Use only the documents I give below, quoted exactly; don't change a word or number. End on the answer the record supports, held for 3 seconds.
