Part 1. Factors That Can Impact Audio and Video Synchronization
When audio and video are not in sync, it can be due to a few different reasons, like problems with your device or issues with the video itself. To fix the problem, you first need to find out what’s causing it. Here are some common things that can make your audio and video go out of sync:
- Streaming Lag
- Device Performance
- Video File Issues
- Software Bugs
When you watch videos online, like on YouTube or Netflix, slow internet connection can cause the sound and video not to be in sync. For example, if your internet isn’t working well, the sound might be behind the video.
Sometimes, your device might be the problem. Old or slow devices can have a hard time keeping the sound and video in sync. For example, if you’re watching a movie on an old computer while downloading something, the video might lag behind the sound.
If you’re watching a video you downloaded or a DVD, the file might have sync problems. This can happen if the video isn’t properly saved or if there are errors on the disc. For example, a movie you downloaded might have a slight delay in sound if the file was messed up.
Sometimes, problems with your video player software can mess up the sync. For instance, an old version of your media player might not keep audio and video in sync correctly.

Method 1: Using Auto Synchronization to fix video audio out-of-sync issues
First of all, make sure you have the newest version of Wondershare Filmora installed. Open the program by double-clicking it, start a new project, and import your video. Then, drag and drop the video onto the editing timeline.
Next, use Filmora’s Auto Synchronization feature to fix the audio and video automatically. It lines everything up without you having to adjust things by hand.
To use it, click on the video and audio tracks on the timeline, right-click, and then choose "Auto Synchronization".
The feature will automatically synchronize your audio and video. Once it’s done analyzing, simply click the “Export” button on the upper right of your screen to save the video on your computer.
Method 2: Using Auto Beat Sync to match video with music clips
Besides Auto Synchronization, you can also use Filmora's Auto Beat Sync tool to make your video match the music you pick. To use it, select your video on the timeline, right-click, and choose “Auto Beat Sync".
In the Auto Montage Panel, you’ll find three main settings:

Adjust the settings to fit your needs, and make sure the audio and video are properly aligned with each other.
Once you've adjusted all the settings, click the "Analyze" button to begin the automatic analysis. The tool will first analyze the beats and rhythm of the background music.
Then, it will automatically highlight and select the best moments from your footage and edit them to match the music's beats. You can preview the result by clicking the "Blank" button or the "Play" icon. If you're satisfied with the outcome, click "Export”. If not, adjust the settings and click "Analyze" again.
