In the context of video editing, broadcasting, or media production, “time codes” are used as a reference system for identifying specific frames or segments within the timeline of a video or audio project. Time codes provide a unique timestamp, often in hours, minutes, seconds, and frames, which helps editors and producers pinpoint exact locations within the media asset for tasks such as editing, synchronization, or archival purposes.
There are various types of time code standards, such as:
SMPTE Time Code: Developed by the Society of Motion Picture and Television Engineers, this is one of the most widely used formats in film and TV production. It is often displayed in the format of HH:MM:SS:FF and can be recorded on video and audio tracks.
Drop-frame and Non-drop-frame: Primarily used in North America for NTSC video, drop-frame time codes account for the difference in frame rate versus real time by periodically skipping frame numbers to maintain accuracy over long durations. Non-drop-frame, on the other hand, counts frames continuously without adjustment, which can result in slight discrepancies.
Time Code in DAWs (Digital Audio Workstations): Software like Pro Tools or Logic Pro uses time codes to help musicians and engineers align audio tracks, MIDI, and automation precisely during the creation and mixing of audio projects. SMPTE is also commonly used here.
When communicating about time codes, professionals may use terms like “TC”, assigned identifiers like “SMPTE”, or context-specific references based on the workflow being employed. The choice of terminology might also depend on regional or industry-specific practices, so it’s always advisable to clarify which system is being referred to during collaborations or technical discussions.
