The document discusses the improvements made from the preliminary task (continuity editing) to the full opening sequence product. Seven key areas were improved: 1) Match-on-action was faster and smoother. 2) Variety of shots was increased for more interest. 3) Mise-en-scene elements were hidden to fit the time period. 4) Audio volume was better balanced. 5) A focus pull was more effectively used to reveal information. 6) Camera work relied more on tripods for steady shots. 7) Color correction addressed lighting changes from location to location. Overall, lessons from the preliminary task led to a polished opening sequence through refinements in these seven technical and creative elements.
