DVD ripping is not always trouble-free and cheif among them is the ripped DVD audio out of sync with the video. Sometimes the audio goes ahead of the video, sometimes there is an audio delay or no audio.
How to avoid DVD sound "lip-sync" problem and bring the out-of-sync audio back to normal after DVD ripping? The good news is that there are ways to adjust the sync settings manually like VLC, KMPlayer, etc. But you have to reset every time you play the DVD movie. In this post, we'll share you a way to permanently fix video audio desync error after DVD ripping caused by Handbrake, VLC, avstodvd, DVDFab, wondershare and others.
Ripped DVD A/V Lip-Sync Problem Occurs with Many DVD Rippers
DVD ripping audio sync errors is common with many free and paid DVD tools.
- " Handbrake used to rip DVD without a problem. Now the audio is out of sync with Handbrake, even with constant frame rate."
- "I use VLC to rip a DVD off to avoid damage by my kids and it seems the video is fine but the audio is off by a few seconds."
- "When ripping DVDs sometimes I will have an audio delay. I use StaxRip and DVD Shrink. One time, when StaxRip demuxed a VOB rip; so all of a sudden lots of files are not out of sync."
- "Video I created with Aimersoft DVD Ripper gives me audio errors - AVI files have no audio at all. MP4 files have audio but it is out of sync." ...
1. DVD encryption tech. Copyright protection tech has caused DVD ripping problems of many kinds and AV desync error is one of them. Make sure the DVD ripper has the capability to remove DRM protection; If not, install libdvdcss (esp. for Handbrake) properly or turn to another program.
2. Mixed frame rates. There are DVDs that use a mixture of the film (23.976) and NTSC (29.970). The two frame rates or "VFR" may cause A/V out of sync after the DVD ripping. Even then, the variable frame rate is acceptable by most video players. If your player can't play the ripped DVD without lip-syncing audio, you need to set the frame rate to a fixed or constant rate.
3. DVD ripping and remuxing. There are people reporting DVD ripping audio sync error with MakeMKV. When using MakeMKV to encode DVD to MKV, the ripping and remuxing are carried out at the same time, which will lead to some kind of ODD latency. This may be the reason for some of the ripped DVD audio sync errors.
4. The video and audio in a DVD is out of sync. Before a user rips the DVD, the disc itself has a A/V sync or Audio Delay error and that results in out-of-sync sound after the DVD ripping.
5. Windows Media Centre doesn't accept your DVD audio channel or WMC doesn't get instantly updated to support your latest DVD disc. The workaround you can try is to upgrade WMC or resort to another media player.
6. Computer or DVD playback device TV issue. There is a good chance of audio delay when ripping DVD on a slow computer, especially under high encoding settings. Plus, if you're seeing audio off sync with video error only on certain movies or certain fragment of film, it's probably not the fault of your playback hardware TV set. If every ripped DVD source has lip-sync issue or no audio error, then the TV is the culprit.
