In post-production, what is timecode primarily used for in relation to video frames?

• A. Timecode is used to align audio with video frames during post-production.
• B. Timecode is used to set color grading tone.
• C. Timecode is used to measure room reverb time.
• D. Timecode is only for internal naming.

Answer: (A)

Timecode provides a precise, frame-accurate timestamp that acts as the shared clock for all media in post-production. This timeline reference lets editors and sound mixers align audio with the exact video frames, so separately recorded dialogue or effects can be synchronized with picture on a frame-by-frame basis. It also supports frame-accurate editing and easy navigation through the edit, cuts, and transitions.

Color grading decisions rely on color information and scopes, not on frame-by-frame timestamps. Measuring room reverb time is an acoustics task, not a media synchronization task. Timecode is more than just a label; it’s the frame-accurate reference that keeps audio and video in lockstep throughout the workflow.
