Postsynchronisation is spelled with the prefix "post-" which means after and "synchronisation" which means simultaneous. It is pronounced /ˌpoʊstˌsɪŋkrənaɪˈzeɪʃən/ in IPA phonetic transcription. The stress is on the third syllable, and the "s" sound is pronounced as /z/ because it follows a vowel sound. This word is commonly used in the context of audio and video production to refer to the process of matching audio and video tracks after recording separately.
Post-synchronisation, also known as post-production sound synchronization, is a technical process used in film and video production to match or synchronize audio recorded separately with the visual footage during the post-production phase. It is essentially the art of integrating sound effects, music, and dialogue with the moving images by precisely aligning them in time and ensuring they are in sync.
The process of postsynchronisation involves several steps. First, the separately recorded audio tracks are carefully examined and edited to remove any unwanted noise or distortion. They are then meticulously aligned with the corresponding visual footage, taking into consideration the lip movement of actors, timing of actions, and overall rhythm of the scene.
This synchronization process can be achieved through various techniques, including manual editing, automated audio software, or advanced digital tools. In addition to aligning the audio to match the visuals, postsynchronisation may also involve adjusting the volume levels, applying equalization and effects, and creating a balanced mix.
Postsynchronisation is crucial in the filmmaking industry as it ensures a seamless audio-visual experience for viewers. It enhances the realism and coherence of the finished product by eliminating discrepancies between sound and image. This process is commonly used for adding dialogue or sound effects that could not be captured during production, or to improve the overall audio quality. It requires both technical expertise and a keen artistic sensibility to achieve a harmonious blend of sound and image.
The word "postsynchronisation" is derived from the combination of two words: "post-" and "synchronisation".
1. "Post-" is a prefix derived from Latin that means "after" or "behind". It is commonly used in English to indicate something that occurs after a specified event or time.
2. "Synchronisation" is derived from the Greek word "synkhronos", which means "happening at the same time". It refers to the act of coordinating or aligning actions, events, or processes to occur simultaneously.
Therefore, "postsynchronisation" combines the meaning of "after" and "synchronisation" to describe the process of synchronizing audio or sound with visual content in a film or video production after the initial recording. It involves matching the sound to match the lip movements or other visual cues on screen.
