Have you ever experienced a lip sync error on Mac? If yes, you surely know how frustrating it can be and how there is no way the video can be perceived normally.

The issue of audio and video out of sync is vital. When the sync value is incorrect, then the audio is either played too early in the movie, or too late. This is commonly known as ‘lip-sync’ issues and it takes a lot from the joy of watching a movie or a home video.

Because media players employ various parts of their kernels for an AV-output sometimes out of sync video on Mac happens. Even though compressed into the same codec, video files are generally bigger than audio ones, and from time to time incorrect timing occurs.

Luckily, there is a way to fix issues with MP4 video audio sync on Mac. Elmedia Player is a player that is very uncommon as it offers the option of adjusting your audio track to fit the video.
