“I have an AVI video which I want to watch, and it seems to be a mess. When the video is played everything goes fine. But, after a few seconds, audio and video will be out of sync, either video comes first or the audio. As the video continues to play, it becomes still worse due to loss of complete synchronization between audio and video streams of AVI file. Can anyone please suggest me a good solution to fix audio-video sync problem with my AVI file? Thanks in advance.”
AVI is the most frequently used video file format to save and play movies or video clippings on various devices.

Synchronization of Audio-Video in AVI File:
AVI video file is a container holding two different streams for audio data and video data. When this file is made to play, both audio and video streams sync its data together to produce a beautiful movie. But, due to many unknown reasons AVI movie goes out of sync, which means audio of a movie will be delayed/pushed forward than the video or vice-versa.

- Type 2: AVI video synchronization will be proper when the AVI video is played, but as the video progresses the difference between audio and video induces and gets worse.
The reason behind these sync problems would be because of incomplete download of AVI file from the internet, usage of wrong multimedia player to play the video, CRC error while transferring AVI video over the network and many more. Whatsoever may be the cause behind AVI file audio-video sync error, there are ways to overcome these problems.
