The document discusses the progression from a preliminary film task to the final product. Some key things learned were using camera shots like match on action and continuous filming. The preliminary task was a good first experience but some shots like the beginning and end were messy. For the final opening, a wider range of shots and editing effects were used to set the atmosphere. Looking back, focusing shots and using more variety would have improved the preliminary task. Comparing the two, there is clear improvement in shots like two shots and tracking shots which were done more perfectly in the final film.
