Pre-mastering

Pre-mastering involves several steps: formatting, imaging, and proofing. Formatting multiplexes (joins) the video and audio tracks into a single track, then organizes the files into the proper configuration. Imaging copies these files to BD-R, or hard disk for proofing and, later, replication. Proofing (also called simulation) is the quality assurance step of the process. Carefully viewing the content and checking navigation will insure that a disc is ready for release. A BD-R “one off“ disc is burned to test the program in different players to assure universal acceptance.
