Optimum image codec and digital enhancement techniques for VDSLR-Based filmmaking

Abstract

Digital filmmaking allows extended variations in every stage, such as development, preproduction, production, post-production, and distribution. Because of the advanced editing tools and devices, it becomes easy to make high quality movies at low cost. Recently, as video-capable digital single lens reflected (VDSLR) cameras are widespread, many people are interested in filmmaking using VDSLR cameras. However, digital filmmaking using VDSLR cameras exhibits two fundamental problems in shooting and editing stages. This paper deals with the use of a VDSLR camera in the production stage and digital enhancement algorithms in the post-production stage for compensating distortions made by the DSLR camera. More specifically, we will provide an optimum use of video codec by analyzing two different editing approaches with and without image compression. We also present digital image restoration algorithms for compensating jello and aliasing artifacts of DSLR video.
