This document compares the filmmaking techniques used in the author's preliminary and thriller film projects. For the preliminary project, shots were mostly mid-shots, lighting was basic, and editing relied on repetitive shot-reverse-shot. For the thriller project, the author used a variety of shot types including close-ups and tracking shots. Lighting employed both practical and non-diegetic sources to create tension. Editing techniques like cross-cutting and fades were experimented with to refine the cut and enhance the thriller genre elements. The author learned from the weaknesses of the preliminary project to improve techniques and produce a higher quality final thriller film.
