The KMPlayer stands strong among major media player for Windows due to its own support for 3D videos and up to 4K display.
So, today we going to learn how to fix audio and video out of sync in KMPlayer.
Syncing of audio and video are processes that should have taking place during the editing process. Most modern and good budget movies do not usually come with this problem, but old movies and some hard coded movies when been converted do have this syncing error. Some poorly edited movies and just some recorded speeches might come having this problem.

and video out of sync with KMPlayer using keyboard shortcut or hotkeys.
Using keyboard shortcut keys will not generally affect you while watching the video and it will be faster, so let’s get
These are the processes that is needed to be taken:
1.  The KMPlayer has inbuilt keyboard shortcut, but the audio sync is not given a keyboard shortcut, so we are going to create one. But you can check my tutorial on top KMPlayer keyboard shortcut or hotkeys.
2.  So first of all, launch the KMPlayer, press F2 on your keyboard, it will load up the Preferences.
3.  The Preferences window will open. On the left hand side, expand the General tab, and Click on Keys/Global Control.

6.  All the resync audio do not have keyboard shortcut, so we are going to create them. You can use any value but I advise using Ctrl + Shift  and then we give value of 1 to 7 for each resync option
7.  So to give the value, click on any of the resync audio and press the keyboard shortcut or hotkey you wish to give and after through click on Close

Resync audio(Back to Normal)
The keyboard shortcut or hotkeys required for this process are
Shift + ctrl + 1 to 7, using the timing of 5 seconds, 50 milliseconds and 5milliseconds to sync the audio to the video.
Shift +ctrl + 1, 3 and 5 stands for audio delay up, should be used when audio is faster than video
Shift +ctrl + 2, 4 and 6 stands for audio delay down, should be used when audio is slower than video.
Shift + ctrl + 7 to return audio to normal state or original state (that is the way it was by default).
So hope you have been able to fix your out of sync audio and video using KMPlayer.
