"As connected platforms such as Twitter, Instagram and TikTok rise in popular use, communication strategies are forced to grow more condensed and to be transmitted primarily across digital screens. Online short-form video has consequently become a primary format for environmental communication, though research on digital communication remains largely limited to frame analysis and discussions of print and still images. Filling a need in current scholarship on environmental media and aiming to further bridge humanities and communication research, this article offers a model for assessing environmentally themed short-form videos that complements communication studies’ focus on messaging rhetoric with humanities-based film and visual culture analytic tools for assessing the connotative aspect of aesthetic and narrative elements. Intending to offer an applicable framework for environmental messengers, we develop a genre system of short-form videos along cognitive and emotional axes that can be quantitatively identified according to formal practices, demonstrated through an examination of four environmental short-form videos."
