EduCam: Cinematic vocabulary for educational videos
Cinematography relies on a rich vocabulary of shots and framing parameters to communicate narrative event structures. This cinematic vocabulary stems from the physical capabilities of camera movement and uses aesthetic aspects to engage the audience and influence audience comprehension. At present, automatic physical camera control is limited in cinematic vocabulary. Virtual cameras, on the other hand, are capable of executing a variety of cinematic idioms. Specifically, shot composition, match cut, and establishing shot sequence are three common cinematic techniques often lacking in automated physical camera systems. This paper proposes an architecture called EduCam as a platform for employing virtual camera control techniques in the limited stochastic physical environment of lecture capturing. EduCam uses reactive algorithms for real time camera coverage with hierarchical constraint satisfaction techniques for offline editing.
