User Query: "I have an MP4 file that I recorded using my camera. But it is running out of sync errors. How to overcome this problem easily? I mean I spent a lot of time recording a video and don’t want to waste more time!"
We can understand how terrible it would be when your favourite videos play with Sync issues! To understand why your MP4 is out of sync, first you need to understand that every MP4 file has an audio and a video track. These audio and video tracks are synced using the time stamps that are created while filming or creating a video. No worries, there are various methods to fix Audio/Video Sync Issues.
But before moving on with the solutions, let’s understand what Audio/Video Sync is and the reasons for the Audio/video sync issues in MP4.
Audio/Video Sync is the process of synchronizing or combining the audio and video data streams with each other. Audio/video synchronization can be done both manually and automatically.
Audio-video sync issues occur when the audio and video components of a media file do not stream and do not sync with time when the audio is ahead or behind the video. The most common causes of audio and visual sync difficulties are differences in particular time stamps. You will also experience sync problems if an audio or video track's portion or frame is broken.
For example, if a video frame is broken, the media player will skip that frame and begin playing from the next. The audio track, on the other hand, will not be skipped to the following frame.
Such situations will cause a delay in MP4 audio, resulting in a mismatch in time stamps and a sync fault. Hopefully, you are now aware of what causes audio and video to be out of sync.
Here are a few reasons that lead to audio video out-of-sync-issues
Incompatible audio and video codecs will cause audio and video out of sync because of each codec uses a different algorithm for compressing audio and video. When audio and video use different codecs, the decoding process for each track may occur at a different speed, leading to a mismatch between the two tracks.
Playing videos on an incompatible video player will cause audio and video out of sync because of different video players use different algorithms and settings for decoding the audio and video tracks of a media player. Different video players use different buffering techniques and processing capabilities, which might also affect the timing of audio video tracks.
Video files that get corrupted during the encoding process might cause audio-video sync issues because corruption will lead to errors in the data. Due to this decoder might not be able to synchronize the audio and video during playback.
Generally, video files are encoded using variable bitrate. If the variation in the bitrate is too large or unpredictable it can cause audio and video sync issues.
Editing the video file after the completion of encoding will cause audio/video sync issues. Because when a video is encoded, the audio and video tracks are compressed and combined into a single file, and if that file is subsequently edited in a way that changes the timing it will cause the audio video out of sync.
When a video file is played using a media player with high bitrate settings, it can cause the computer to struggle to process and playback the file. This can result in dropped frames or skipped audio, which can cause the audio and video out of sync.
Here are some quick ways to fix audio/video sync issues
Many media players have settings that allow you to adjust the audio/video out of sync manually. Look for options that allow you to delay or advance the audio track by a few milliseconds, and try adjusting these settings until the audio and video are in sync.
Try playing the same video file in a different media player to see if the sync issue persists. Some media players may handle certain video codecs or bitrates better than others, and switching to a different player may help resolve the issue.
If the video file is out of sync due to a codec or encoding issue, you may need to re-encode the video using different settings. This can be done using video editing software or dedicated encoding software. Be sure to use settings that are appropriate for the type of video you are working with.
If the audio and video tracks are only slightly out of sync, you may be able to manually adjust the audio track in video editing software to restore sync. This involves shifting the audio track forward or backward by a few frames to match the timing of the video
If the video file is corrupt or was not ripped properly, it may be necessary to download or rip the video again. This can be done using a different source or different ripping software.
