Resolution affects audio and video sync. This article explains why resolution affects audio and video. It also shows how to adjust the resolution to keep audio and video sync with 3 tools: MiniTool Video Converter (Desktop), MiniTool MovieMaker (Desktop), and CloudConvert (Online).
Overview of Resolution
Resolution refers to the total number of pixels in each frame of a video. The higher the resolution, the more pixels there are. Resolution determines the details in a video, particularly its realism and clarity. Usually, resolutions include HD resolution, SD resolution, and more.
Overview of Audio and Video Sync
Audio and video sync refers to the audio and video content in a video that are perfectly aligned without time gaps. If a time gap occurs, it’s called a synchronization error. The synchronization error is divided into positive and negative ones. The positive one indicates that audio precedes the video, while a negative one means that video precedes the audio.
How Resolution Affects Audio and Video Sync
When the resolution exceeds the video’s decoding and storage capabilities, the audio and video can be out of sync. Some players can’t adapt to high or low resolutions, leading to buffering. That can also cause audio and video to become out of sync.
To restore audio-video sync, we can adjust the resolution to an ideal state.
