How to Fix Audio and Video out of Sync (Synchronization)


After creating, editing a video, sometimes when you try to upload it on YouTube, YouTube tells you that there is an audio sync issue with video. Well today we will be checking out how to solve this audio and video synchronization problem using a software, Handbrake.

Majorly we will be dealing with the framerate in order to solve this issue, FPS (frame rate per second) is a property of a camera and usually set in the camera, before recording a video, so camera can shoot video at different framerate depending on the quality of the camera (5, 10, 12, 15, 23.976, 24, 25, 29.97, 30, 50, 59.94, 60 Frame Rate per second, FPS).
First we need to know at what framerate our video was shot. To do this
1.     Go to the location of the video,  then the properties window opens, click on Details
Video Properties

2.     In the Video section below, you can see the Frame rate, the last on the list, these was shot at 30 frames/second.
