What does an ADR/Dialogue Editor do?

The ADR Editor and the Dialogue Editor are usually two different technicians on big budget films. On some very big films, there may even be one ADR and one Dialogue Editor for every reel of the film. On medium to low budget films, these two roles are usually carried out by the same person.  

Dialogue Editors start work on a film well into the picture editing process. They attend a spotting session with the other Sound Editors to discuss and note all sound issues. All the lines of dialogue are carefully scrutinised for problems. These might be technical, such as the sound of traffic over an actor’s line, or performance-related. In some cases an actor might mispronounce a word or be inconsistent with an accent.

ADR/Dialogue Editors review the original sound files to check whether these problem sections can be replaced. Using an editing software programme, ADR/Dialogue Editors cut between a number of takes (sometimes even using different syllables from each take) to create clean, crisp lines of dialogue. If this is not possible, Automated Dialogue Replacement is used.

During ADR sessions, actors watch themselves on screen, and re-voice as accurately as possible. They have to make sure that their lines are synchronised with the pictures (lip-sync), and that their performance matches the original. Actors may also have to record new lines for off-camera dialogue to help make difficult scenes work. During ADR sessions, ADR/Dialogue Editors have to make quick, accurate decisions about whether the performance is good enough.

These sessions are extremely expensive and difficult to co-ordinate because of actors’ limited availability. Sometimes these are done remotely. However, for large amounts of dialogue re-recording, experienced ADR Mixers are hired to work closely with the actor(s) in situ. 

After the newly recorded ADR has been edited into the original dialogue track, ADR/Dialogue Editors work on the background or ambient sound. They have to match this up using frames or fractions of frames from other sound takes. During the Pre-Mix (the first dubbing session), all the dialogue and ADR is smoothed out (cross faded), and any mistakes are corrected. This is usually the end of most ADR/Dialogue Editors’ work, although on big budget films, they may be involved until after the Final Mix.

ADR/Dialogue Editors may be freelance, or they may be employed by an Audio Post Production House. They work long hours.

What is the best route in?

You can usually start out as a runner in a Sound Studio or Audio Post Production House. You can then progress to Assistant, working with in-house Sound Editors or ADR Re-Recording Mixers. As a junior in an Audio Post Production Houses you can make contact with freelance Sound Editors, who may take you on as an assistant.
