It's often the case that when customers rip DVD or convert video with Handbrake, the output audio lagged several seconds or more behind video. To liberating customers from the error that the same video/audio desynchrony in Handbrake, MacXDVD today specify the reasons and solutions for Handbrake output audio and video out of sync problem.

What Causes Handbrake Output Audio Not Match up with Video

It shall be notified that Handbrake doesn't cause the video audio sync problem. Instead, such issue is resulted from the following cases:

1. The decoder/playback device.

The media players such as Windows Media Player, VLC and QuickTime sometimes have a hiccup. Take QuickTime for instance. It may have timescale issues when bringing MPEG source into Avid or Final Cut Pro, which may make audio go out of sync with video.

2. Encoding video with intense features.

If you are working on a slow computer with low configuration but encoding video with high refs, CABAC Entropy coding, 8*8 transform, Pyramidal B-Frames, etc, your audio and video will be not synced correctly.

3.Get the computer system restarted.

The intensive use of CPU can lead your system go wacky. So the processes like video encoding, editing or downloading will not go smooth. This is also the cause of audio/video out of sync.

4. Be careful of Xvix.

When customers are encoding an MPEG-2 content, be selective in the codecs. For the older ASP codecs like DivX and Xvid, and the previous .avi container, customers are not suggested to choose them as they are usually considered as the crime culprit of audio/video sync issues.
