If such tools inadequately add an extra delay to the video or soundtrack, you'll experience this issue. Some inefficient video editors handle audio-video sync carelessly. Here are some scenarios:įor downloadable video files with audio tracks, the synchronization issue starts from when the audio and video data were being mixed. If video files are not handled correctly, this synchronization error could occur. You get the video audio sync error (VLC sound delay, in this case) if some data is lost either from the audio or the video. Video files or audio-video streams contain synchronization mechanisms. This amount could be a positive or negative value If the value is positive, this means the audio leads the video while a negative value indicates that the soundtrack lags the video. The lip-sync or audio-to-video sync error is the amount of time the soundtrack or audio deviates from perfect synchronization with the video. When this happens, it's said that the audio and video are out of sync. Sometimes, the soundtrack might be faster than the video or video faster than the soundtrack. Lip-sync, which is also called audio-to-video synchronization, is the relative timing between the video (which is a bunch of fast-paced images) and the soundtrack or audio associated with it. You do not necessarily need to download the video again from another source since audio-video sync can easily be fixed.
