duplicate scene playing mkv file in kmplayer
Solution 1:
If your KMPlayer is Updated: 1.Right click on the screen. A list of options appears. 2.Goto 3D Screen Controls in those options. 3.Select " Side by Side -> 2D ".
Solution 2:
In VLC this can be done by cropping one side of a video. Effects - video - crop right or left 960 pixels if a video is 1920 pixels wide. (1920/2=960). Then you force aspect ratio 32:9 (instead of 16:9; 16x2=32) in preferences-video.
