Automatic dialogue recording

from Wikipedia, the free encyclopedia

The English term Automatic Dialogue Recording (ADR) ( German : automatic dialog recording), also Additional Dialogue Recording (German: additional dialog recording) or Automatic Dialogue Replacement (German: automatic dialog replacement), describes the subsequent recording of dialogues in professional film post-production . The process is part of the post-production of the film .

Reasons for the ADR can be:

  • The dialogue recorded during filming is inadequate in terms of content or technology.
  • Dialog fragments should be added later.
  • The film has no original sound (for example in the case of animated films).
  • The film is to be translated into another language. In this case, the term voice synchronization is often used .

technology

For the ADR, the film is divided into so-called takes . These are short sections of the film that are then worked through section by section.

A distinction is made between on and off takes. On-takes are the language takes in which the speaker is within the film image. Off-takes are those in which people speak outside of the film image. With the on-takes, care must be taken when recording the ADR that lip-synchronicity is maintained. After the recording with the actors has been completed, the recorded dialogue fragments are usually technically post-processed in order to additionally increase the lip-synchronicity.

Usually the following people are involved:

  • The actors
  • The director (selection of actors and actor guidance)
  • A synchronous editor (responsible for lip-synchronicity)
  • A sound engineer (responsible for the sound / sound perspectives)
  • Possibly. the reception manager (coordinates the process / dates)

So that the recordings can later be used for different locations in the film, they are recorded as "dry" as possible, that is, without reverberation. Then in the later film mixing Hall , Echo and other necessary audio effects added. A neutral sound is often achieved by the actors being in what is known as the "tent" when speaking. The tent is a construction made of heavy materials that absorb diffuse sound .
