Scratch Track

A temporary audio recording used on set as a reference for later production sound


Definition and Use

A scratch track is a provisional soundtrack—often recorded by the director or script supervisor—capturing dialogue or performance during camera rehearsals. It provides editors with sync reference and pacing cues before the final production sound is processed.

Production Workflow

  • On-Set Recording: While primary sound mixers set up, a scratch mic captures backup dialogue.
  • Editorial Reference: Editors use scratch tracks to assemble picture cuts and guide sound design until high-quality production audio is conformed.

Limitations and Value

Scratch tracks are typically low-fidelity and may include background noise or mic handling artifacts. Despite their flaws, they are invaluable for maintaining editorial momentum when final sound mixes are pending.
