What does ADR stand for in film production?

ADR stands for Automated Dialogue Replacement, a crucial technique in film production used to improve or enhance the audio quality of the dialogue recorded during filming. This process involves re-recording dialogue in a studio, allowing actors to match their original performances while ensuring clarity and eliminating unwanted background noise that may have been present during the initial shoot.

Using ADR is especially important when external sound conditions are not ideal, or when filmmakers need to alter dialogue for creative reasons, such as correcting lines or adjusting the performance. This refinement ensures that the film's audio is clear and consistent, significantly contributing to the overall quality of the final product.
