Color effects for compressed digital video
Abstract:
Implementing color effects in compressed digital video is improved upon by re-using the original video's compression parameters during the re-encoding stage, such that the parameters do not need to be re-estimated by the encoder. This improved method reduces complexity and also improves quality. Quality is improved due to re-use of the compression parameters since accumulated error which is common when re-encoding compressed video is prevented. For digital negatives, the effect is able to be implemented even more efficiently.
