Using videos to prototype allows HCI researchers to rapidly explore the design of interactive system including its interaction and context of use. According to my preliminary study with HCI researchers, students and professional interaction designers, the amounts of resources and time required for video capturing and editing are the main obstacles to do video prototyping. While the use of video prototypes can be found throughout academia and industry, i found few works that address these obstacles.
