The Art of Post-Production Dialogue
Automated Dialogue Replacement (ADR), also known colloquially as “looping,” is the post-production process of re-recording dialogue in a controlled studio environment to replace the audio that was recorded on set. This is done for a variety of reasons: the original production audio might be unusable due to background noise (like a plane flying overhead), a technical malfunction, or the director may want a different performance from the actor or need to change a line of dialogue for clarity. During an ADR session, the actor watches the scene on a screen—often on a “loop”—and attempts to match their new performance to the lip movements of their on-screen self.
The Function of the Looping Note
A looping note is the critical piece of direction that guides this performance. It is a specific, actionable instruction for a single line or even a single word. These notes are prepared beforehand by the ADR supervisor, often in collaboration with the film’s director and editor, after they have reviewed the film and identified which lines need to be replaced and exactly what is required from the new performance. The note’s purpose is to communicate the precise emotional tone, intensity, rhythm, and technical requirements needed to make the new dialogue blend seamlessly with the original footage.
Examples in Practice
Looping notes are not vague suggestions; they are precise commands. An actor’s cue sheet for an ADR session will list the line of dialogue alongside its corresponding note. Examples include:
- Technical Notes: These focus on matching the physical reality of the scene.
"Match the on-screen breathlessness. You just ran up five flights of stairs.""This line needs to be a whisper to sound intimate.""Project more. You're shouting across a crowded room."
- Performance Notes: These focus on the emotional intent of the line.
"More urgency here. The bomb is about to go off.""Emphasize the word 'never' to show her resolve.""Add a touch of sarcasm. You don't believe what he's saying."
- Sync Notes: These focus on the technical challenge of matching lip movements.
"You need to say this faster to match the sync.""There's a head turn in the middle of this line, so add a slight pause there."
By following these notes, a skilled actor can deliver a performance that not only sounds pristine but also perfectly matches the visual context and emotional truth of the original scene.
