Audiovisual design might impact emotional responses, as studies from the 1970s and 1980s on movie and television content show. Given today's abundant presence of web-based videos, this study investigates whether audiovisual design will impact web-video content in a similar way. The study is motivated by the potential influence of video-evoked emotional responses to related activities in a web-based learning environment. To examine this, a video scene was designed that follows the concept of an educational trigger video. A trigger video aims to evoking affective responses in viewers with respect to a social problem situation. An experiment was conducted that explored whether the manipulation of two audiovisual design variables--shot length and camera height--of a web trigger video affects how the problem situation and the characters are perceived. The results showed that audiovisual design did impact these video-related tasks.
