The paper examines the role of visual reasoning in ecology awareness documentaries, focusing on the analysis of film editing. The effective use of specific visual reasoning tools in these documentaries results in their greater influence on the viewers and consequently leads to a certain reaction on a film. The study considers two ecology documentaries produced in 2021 and 2024, identifying various film editing techniques such as hard cut, jump cut, L-cut, J-cut, match cut, cutaway shot, insert shot, and cross-cutting. The research reveals most frequent film editing techniques according to documentary modes. These techniques contribute to creating suspense, tension, and a sense of urgency, effectively illustrating the drastic ecological changes and human impact on the environment. The paper also discusses the potential for deeper interdisciplinary investigations into the unique strategies of documentary filmmaking and their presentation from different angles, such as cinematography, drama, direction, and language. Additionally, it raises the possibility of using documentaries for didactic purposes in higher education programs, given the increasing prevalence of video as a medium of study.
