The Sweet Spot: Optimal Video Length for Sustaining Student Views and Efficient Production

This study examines the optimal length for educational videos to enhance student viewing and efficient production. While shorter videos are often preferred, they require more time to cover topics comprehensively. Contrary to previous studies recommending fixed short videos, this study hypothesizes that students watch longer videos proportionally. Analytics from over 100 videos showed an average watch time of 65.76% for videos ranging from 6 to 30 minutes. This challenges the idea of fixed short videos. The study proposes a video production plan with a Takt Time of 30 minutes as the maximum length to maximize efficiency and ensure timely availability.
