Abstract: A spiral buffer for a non-linear editing system digitizes and stores an input video signal as it is simultaneously being cataloged by an operator. The digitized video signal is stored in a circular buffer of a random access non-linear storage device, such as a disk recorder, with the oldest video being overwritten by the newest video when the buffer is full so long as the oldest video has not been marked by the cataloging process to be kept. The marked video is edited, further pruning the video in the buffer. The pruning of the video in the circular buffer results in a spiral shrinking of the buffer.
