what is adr in film

ADR in film stands for Automated Dialogue Replacement. It is the process of re-recording the films audio in a controlled and quieter setting, typically at a recording studio, to replace or augment the initially recorded lines on set. ADR is used to improve sound quality, reflect changes in dialogue and performance, and incorporate new lines or non-verbal sounds into the film. It is also utilized to address production problems such as background noise and to enhance performance. ADR recording sessions involve the original actor re-recording their lines to keep the voice consistent and in sync with the mouth movements of the original shot. The process requires precision and skill to ensure that the replacement audio looks and sounds natural.
