What is ADR in Film?

Film post-production accounts for a significant portion of studio budgets, and ADR (Automated Dialogue Replacement) plays a crucial role in this process. ADR is the process where actors re-record their dialogue in a studio to resolve audio issues that occurred during filming.

The Difference Between ADR and Dubbing

While both ADR and dubbing replace original dialogue, they differ in purpose and method. ADR focuses on the original actor re-recording dialogue in the same language to correct audio quality or mistakes. In contrast, dubbing involves a new actor performing the character in a different language, which can lead to differences in emotional delivery. ElevenLabs has developed AI voice technology to overcome the limitations of dubbing. This technology localizes content into over 90 languages while preserving the original actor's emotions and vocal characteristics.

Why ADR is Necessary

On location shoots, it is difficult to secure clean audio due to uncontrollable factors such as wind, traffic noise, and staff movement. ADR allows for clear audio quality to be secured in a soundproof studio. Key use cases include:

• Overlapping Dialogue: Securing clean audio for each character in chaotic scenes where multiple people speak simultaneously.
• Dialogue Modification: Handling necessary dialogue changes due to broadcast regulations or legal reasons without reshooting.
• Performance Completion: Enhancing final quality through ADR when the video is excellent but the audio quality is lacking.

AI voice tools contribute to accelerating these ADR workflows and reducing studio time, quickly becoming an industry standard.
