Chapter 3. Synchronization and SMPTE Time Code

In film and video two different media, visual and auditory, must be experienced together. In order to create sound that works seamlessly with visuals, two playback systems are necessaryone strictly for audio and another strictly for video. These two systems must be capable of playing back together in perfect time. The process of making two or more distinct audio or visual systems play back together is called synchronization .

Synchronization is a basic principle of working with audio for video and film. Any alteration of the audio must be done in the context of the visual image. It wouldn't be possible to establish and control the relationship between the two media without synchronization. A thorough mastery of the concepts and practices of synchronization will become invaluable as you get deeper and deeper into audio post-production. This chapter is devoted to synchronization theory, techniques, and real-world practices that you will use every day when creating sound for films and video.
