The document discusses the key lessons learned from the preliminary task to the full product. For the preliminary task, there was little planning which resulted in issues like not enough camera angles and shaky footage. However, for the full product extensive planning was done around booking equipment, scheduling filming dates, and writing scripts. This improved the quality of filming. Other improvements included using a higher quality HD camera and microphone rather than a handheld camera. For editing, using Final Cut Pro instead of iMovie provided more advanced editing tools that enhanced the overall film.
