Combined editing and VFX process using metadata for efficient post production

Abstract

Advanced imaging devices and the related production environment necessitate highresolution image processing techniques. In this context, optimization of processing time and amount of data in the workflow attracts increasing attention in both large-scale commercial film production using 4K and stereoscopic three-dimensional (S3D) cameras and small-scale independent film production using digital single lens reflected (DSLR) cameras for full HD outputs. Digital picture exchange (DPX), which is a common standard file format for digital intermediate (DI) and visual effects (VFX), requires greater amount of data than the original image without compression. This paper presents an efficient method that can minimize processing time and amount of data between editing and VFX processes using metadata. The proposed method can significantly increase productivity in both large and small production studios.
