ABSTRACT
Our goal is to help automate the capture and broadcast of lectures to remote audiences. There are two inter-related components to the design of such systems. The technology component includes the hardware (e.g., video cameras) and associated software (e.g., speaker-tracking). The aesthetic component embodies the rules and idioms that human videographers follow to make a video visually engaging. We present a lecture room automation system and a substantial number of new video-production rules obtained from professional videographers who critiqued it. We also describe rules for a variety of lecture room environments differing in the numbers and types of cameras. We further discuss gaps between what professional videographers do and what is technologically feasible today.

Towards virtual videography (poster session)
MULTIMEDIA '00: Proceedings of the eighth ACM international conference on MultimediaVideographers have developed an art of conveying events in video. Through choices made in cinematography, editing, and post-processing, effective video presentations can be created from events recorded with little or no intrusion. In this paper, we ...
Virtual videography
Well-produced videos provide a convenient and effective way to archive lectures. In this article, we offer a new way to create lecture videos that retains many of the advantages of well-composed recordings, without the cost and intrusion of a video ...
A framework for virtual videography
SMARTGRAPH '02: Proceedings of the 2nd international symposium on Smart graphicsThere are a significant number of events that happen on a regular basis that would be worth preserving on video but for which it is impractical to use traditional video production methods. In this paper, we describe one possible way to inexpensively and ...
