AVratio

AVratio, also known as the Audio-Video Ratio, is a term used in video editing and production to describe the synchronization between the audio and video streams within a media file. It refers to the precise alignment of sound events with their corresponding visual actions. Ideally, the AVratio is perfect, meaning that every sound precisely matches its visual cue.

Deviations from a perfect AVratio are often referred to as "sync issues" or "audio drift." These can occur for various reasons, including differences in recording equipment, file processing, or even playback software. While minor AVratio discrepancies might go unnoticed by casual viewers, they can become a significant distraction in professional productions, impacting the viewer's immersion and perception of quality.

Editors use specialized tools within their software to analyze and correct AVratio problems. This typically involves adjusting the timing of either the audio or video track until they are perfectly aligned. Achieving a correct AVratio is a fundamental step in the post-production process, ensuring a seamless and professional viewing experience. The term is most commonly encountered when discussing video playback issues or during the technical aspects of video editing.
