Solve Handbrake Video Audio Out of Sync Issue When Converting Video Format

Speaking of HandBrake, it should be no stranger to you. It is a popular tool for DVD/video conversion, but sometimes the Handbrake output video and audio is out of sync, like the case below:

" I just started using Handbrake to change the video format from .mkv to .mp4 so I can play them on my TV. But now some of them have the audio and the video out of sync. The original video is good (.mkv files), but when I change the format, the new video is out of sync with the audio. I have tried to change the resulting format as well, to .avi and .m4v with no luck. The problem happens just as the video starts, the audio kicks in like 1 or 2 seconds before the video and it is like that until the end. Thanks a lot for your help."
