The preliminary task had a very limited time of 45 minutes to film a basic storyline. For the thriller project, the group watched other thrillers for inspiration and came up with the idea of an "Apparition". They storyboarded scenes, conducted test shoots, experimented with sounds, and arranged official shooting over multiple days. Though they wished for more editing time, the completed opening sequence for the thriller was an improvement over the preliminary task due to its more complex storyline, varied camera angles, and better special effects.
