jälkiäänitystä

Jälkiäänitys, or post-synchronization, is a post-production process in filmmaking and other visual media where dialogue is re-recorded and synchronized to the picture after filming has been completed. This technique is commonly used when the original on-set audio is of poor quality due to background noise, microphone issues, or an actor's performance during filming. It allows for cleaner and more intelligible dialogue.

The process involves actors returning to a studio to re-perform their lines while watching the filmed scene on a screen. They aim to match the timing and emotion of their on-screen performance as closely as possible. Professional voice actors or dubbing artists are often employed for this purpose, especially in international productions where the film is being translated into another language. This is known as dubbing.

Beyond correcting dialogue issues, jälkiäänitys also facilitates creative choices. Directors can choose to alter lines for clarity, humor, or to better suit the narrative. It's also essential for adding sound effects and music that are mixed in during this stage to create the final audio landscape of the film. While sometimes controversial for its potential to alter an actor's original performance, jälkiäänitys remains a crucial tool in modern media production for achieving a polished final product.
