QuickTime Movie One technique for cataloging behaviors is to preserve them as video images on magnetic tape.
Video tape offers many advantages as a storage medium.
First, and perhaps foremost, it is cheap. Many behavioral sequences last for hours and, except for situations where time-lapse techniques are applicable, the use of film is beyond the financial scope of most research projects. Secondly, it is durable. Commercially available video cassettes can store up to 6 hours of data in a durable package. In contrast, films degrade in quality with time reducing their suitability for archiving.
