Abstract

A system for editing video material comprises: (a) first digital data handling means for receiving and storing a sequence of image frames of relatively high quality; (b) means for converting the sequence of image frames into a corresponding sequence of image frames of relatively low quality; (c) second digital data handling means for receiving and storing the science of relatively low quality image frames; (d) operator input means associated with the second data handling means to enable manipulation of the sequence of relatively low quality image frames for edit decisions to be made; (e) communication means connected between the first and second data handling means, for communicating to the first data handling means edit decisions after manipulation of the frames in the second data handling means, substantially as such decisions are made; (f) means within the first data handling means for processing a first edit decision, and for manipulating the relatively high quality image frames accordingly, whilst the operator manipulates the relatively low quality frames in the second data handling means to make a second edit decision for communications to the first data handling means; and (g) means within the first data handling means for producing an output sequence of relatively high quality image frames in accordance with the first, second and any subsequent edit decisions communicated from the second data handling means. <IMAGE>
