System and method for minimizing transfer of motion picture data manipulated with outsourced labor to allow locations with low bandwidth communications links to be used. Allows for transfer of a small version of a workpiece, e.g., a compressed version of an image, receipt of manipulation commands from outsourcing site and application of commands on original data locally. For example, allows for the transfer of at least one JPEG image (at various compression factors, lower color depth, or resized to a smaller number of pixels) to an outsourcing location wherein the transfer results in a small transfer of image data over the communications link. The outsourcing location then performs operations on the compressed data, e.g., rotoscope, mask, remove scratches, etc. The operations are then sent back (a small transfer of command data) and applied to the original image. By avoiding transfers of the original image to/from the outsourcing location, large amounts of data transfer are avoided.
