Some people would ingest the footage in a video editing software of choice, play the video, or scrub through the timeline to find interesting bits. Copy those onto the timeline. Cluster them by topics, perhaps adding a title above a certain section to group them togethere and find it easier to move between sections. Then they would rework the timeline decidign on a order and gradually, slowly, painfully get to a video sequence. By that point they are generally exausted and iteration or big variations from the current version are not a welcome sudgestion, because of the overheads they involve. Sounds familiar?
