This paper explores the challenges of filming as a qualitative research method in practical school subjects. We exemplify with an observation study using video data collected from lessons in Home Economics, but the issues we discuss are also relevant for other subjects with practical elements, such as Arts, Crafts, Music, Physical Education, and Natural Science. Based on a reflexive thematic analysis of sixteen videotaped Home Economics lessons, we discuss how potential limitations arise due to group work, obstructive furnishings, unpredictable movement, and the use of artefacts. The paper concludes with a discussion about the need to balance intrusiveness and visibility, the struggle to capture everything, the potentially problematic emphasis on visual data, and a section with recommendations for successful use of video as a research tool.
