Abstract

Inexpensive multimedia computers offer new possibilities for mixing video and computer images, videotaping these mixed images, and extracting quantitative data from videotape. In this paper we describe methods for mixing images from a video camera and a Macintosh computer display using chroma keying, and we describe a simple circuit for analog video mixing and frame-counting. We present three applications of these video mixing methods to our neurophysiological and behavioral research with awake, behaving animals. These technologies enhance accuracy, speed, and flexibility during experiments, by allowing us to record an information-rich videotape of the subject and state of the experimental apparatus. After the experiment, these technologies facilitate selecting and extracting quantitative data from the videotape for further analysis. The videotape is especially useful in resolving minor inconsistencies or incomplete information in the notes and data files that often arise during analysis of complex experiments.
