Dubbing (also known as re-recording) is the post-production process of adding new dialogue, vocal recordings or other sounds to an already existing motion picture and the original recording.
It All Begins with Adaption
To us, it is not enough that each sentence length matches the length of the lip movements of the actor. We also strive to match the bi-labials (where the lips of the actor come together) as much as possible. This will allow the audience to forget that they are watching a dubbed production and make it easier for them to fully immerse into the action.
In Lip Sync, every movement of the on-screen actor’s lips are analyzed, adapted to the target language, and delivered with great precision by our talented voice actors. This requires a lot from the voice talent, as he/she should not only match the speed, tone and personality of the on-screen character, but also read the lip movements and make sure that this is all in sync. This technique is seen as the most precise types of dubbing and when done right, the result will show a match of the foreign language lip sync that fits the original presentation and recording.
Phrase Sync is often used for replacing an existing voice, such as a narrator in a documentary. In Phrase Sync, the voice-over starts and stops at the same time as the original speaker. This means that we pay attention to the original timing of the recording and less attention to the lip movements as in Lip Sync.
Phrase Sync can either be a method of ensuring a timed voice-over down to phrase level, or it can be used when utilizing over-dubbing – where you hear the original voice for just a second or two, and then the voice is faced in volume and a replacement localized voice comes in on top.
Automated Dialogue Replacement (ADR) is about replacing or adding audio to sound you have already recorded on set. It is used when the existing audio fails to meet the requirements. This might be that the audio of a filmed scene is not good enough. Typically, the original actor will then, through lip sync, re-create the same dialogue under more controlled conditions in a studio.
