One of the most common and annoying issues for video playing is that audio is not synchronous with the video. As the editor of a video software house, I always receive the same or similar questions mentioned above from different readers that why this audio out of sync problem, always happens and how to fix audio sync problems. Here I picked some common issues:
Q: Ripped a DVD of mine and found an improper audio to video sync. What's the easiest way to fix this?
Q: I have an AVI video file which I downloaded from the web. But it's with out-of-sync audio. How can I fix this problem? I mean I spent several hours downloading this to my computer.
So think about it. In a movie, when a couple are pouring their hearts out to each other, and the audiences are supposed to be deeply touched by the touching love, but what you see is not on the same track as what you hear. That was, as you can imagine, a frustrating experience!
I know that most of the readers are average person and so far have been a stranger to the excessive professional sync issue. Thus, to give you a simple, clear solution to audio/video sync, I turned to the technical teammates for help, and accessed relevant information.
