![]() As each scene is combined with the others to make the final product, their respective Time Codes are synchronized with new Time Code being recorded to the final product. An example would be a video editor that synchronizes with Time Code from a number of prerecorded scenes. In other applications, namely video, the equipment uses Time Code internally to synchronize multiple Time Code sources into one. Video tape often makes similar use of a cue track or one of its audio sound tracks to record and play back Time Code. ![]() An example of this would be a multi-track audio tape deck that is providing Time Code on one track and sound for the production on other tracks. The source can be a dedicated Time Code generator or it can be (and often is) a piece of the production equipment that provides Time Code in addition to its primary function. In many applications, a Time Code source provides the signal while the rest of the devices in the system synchronize to it and follow along. Although SMPTE uses many references from video terminology, it is equally useful for audio-only applications. The signal is usually distributed via standard audio equipment or encoded directly into the video signal (more on this later). The Time Code signal is formatted to provide a system wide clock that is referenced by everything else. The chief purpose of SMPTE Time Code is to synchronize various pieces of equipment. A complete list of these sources is at the end of section 3. It contains a section on Time Code theory and applications and a section devoted to wiring and audio signal distribution. We also recommend "The Sound Reinforcement Handbook" by Gary Davis and Ralph Jones for Yamaha. which provides a complete treatment of the subject as well as an appendix containing ANSI Standard SMPTE 12M-1986. We highly recommend "The Time Code Handbook" by Cipher Digital Inc. If you plan many SMPTE applications, we suggest that you obtain additional reference sources. ![]() The information in this guide is gleaned from many sources. The guide is divided into three sections: section 1 covers SMPTE Time Code basics, section 2 provides an overview of how Time Code controls ETC consoles, and section 3 covers more technically oriented aspects of SMPTE. This Quickguide provides an overview of SMPTE and its implementation in ETC products. ETC has designed SMPTE Time Code receivers and associated software into a number of products to allow the user to synchronize lighting events with other SMPTE devices. Because AV equipment is already set up for SMPTE time code, the logical choice was to embed a SMPTE reader into the lighting console. Lighting consoles are often required to work in concert with audio and video equipment during all phases of a production. The increasing sophistication of lighting in the entertainment industry has placed a greater demand on the synchronization of lighting control. The introduction of SMPTE Time Code provided this frame accuracy and incorporated additional functionality. A number of methods were employed in the early days, but because of the inherent slippage and stretching properties of tape, frame accurate synchronization met with limited success. The challenge originally faced with videotape was that there was no "frame accurate" way to synchronize devices for video or sound-track editing. SMPTE, pronounced "Simp -tee", is an acronym for the Society of Motion Picture and Television Engineers. txt file is free by clicking on the export iconĬite as source (bibliography): Clock Cipher on dCode.SMPTE is a time code synchronization protocol originally developed for use in the television and motion picture industry to deal with video tape technology.
