HandBrake Audio out of Sync – Reasons and Solutions for HandBrake Video Audio Desynchrony Problem

Handbrake is a popular tool for video/DVD conversion, but sometimes the Handbrake output video and audio is out of sync, like the case below:

"I'm trying to use handbrake to copy some DVD discs that I've got. Everything runs normally, but when I open the completed files, the audio is a second or more after the corresponding part of the video. I've searched for things like 'audio sync' and 'lip sync', but I haven't found anything that helps."

Why HandBrake Output Video/Audio out of Sync? How to Solve It?

HandBrake audio out of sync issue may happen when users convert DVD to MP4/MKV, or convert videos to MP4/MKV. And the reasons for MP4/MKV audio out of sync problem may lie in following cases:

The decoder/playback device.

Sometimes Windows Media Player acts funny and so does QuickTime when it's choking. Even VLC will hiccup and sometimes go out of sync. You have to understand, H.264 is a CPU intensive codec even in playback. So, try another powerful player like 5KPlayer to see if the audio is still out of the sync with the video from Handbrake.

A system reboot is necessary.

When processing video editing, encoding, or downloading, the system goes all wacky. This has an effect on playback programs, sometimes making the video go out of sync with the audio.

Maybe you're encoding with intense features.

High refs, b-pyramids, 8x8 and even CABAC, can slow down the video behind the audio. Thus, a slower machine is likely to encounter audio out of sync issue.

Are you using Xvid? Then yes, you may have problems then.

Older ASP codecs like DivX and Xvid and the ancient .avi container they use are notorious with A/V sync issues when encoding from MPEG-2 content.

HandBrake Framerate Setting

Framerate need to be adjusted.

Solution 1. Make sure to use "Constant Framerate".
By default, "Variable Framerate" is checked when you use HandBrake to encode videos or rip DVDs. But that may cause issues with sync, especially when demuxing the file. So specify "Constant Framerate" following Output Settings -> Video -> Framerate(FPS), preview it and see if the video matches the audio.

Solution 2. Change framerate.
Open HandBrake -> load the file with video audio out of sync problem by clicking "Source" and then "Open File" -> press "Video" tab under Output Settings, and then specify a proper framerate from the drop-down list. And then click "Preview" on the navigation bar, and check if the audio out of sync problem has been fixed. If not, try another framerate.

HandBrake video audio desynchrony problem is possible to be fixed by resetting framerate. However, some users point out that HandBrake output video plays fine on PC, but after being transferred to Android, iPhone or other device, A/V doesn't match up properly again. If this is the case, you can find a HandBrake alternative to solve Handbrake output video/audio out of sync issue.
