How to Convert 3D HSBS Video to 2D using Avidemux


Avidemux is a free and popular video conversion tool that is used to edit videos and apply different effects. Using this tool, you can convert 3D half side-by-side (HSBS) videos into 2D. When you make such a conversion from 3D to 2D, you will be able to watch HSBS movies in normal screens of your laptop or PC display.

Unlike when using VLC to convert from 3D to 2D while playing videos, the changes made by Avidemux are permanent. So you can watch the movie file in any 2D screen at your convenience. This open-source program is supported across several platforms including Windows, Mac OS X and several distributions of linux such as Ubuntu, Debian and Mandriva.

To convert or encode HSBS 3D videos to 2D using Avidemux, follow these steps:
  • Download Avidemux from it's official website, install it and open the software.
  • Click on "File > Open" and browse/open the 3D video file you want to convert.
