I have a 3D movie (.MKV), with side-by-side 3D, and it works just fine at home. Now I want to see it at my friend's house, and they don't have a 3D system.

Is there any way to crop one of the sides on VLC or convert it to 2D?

My friend uses a Mac, but I can use Mac OS X or Windows 7 to play the file.

  • he has a mac, but he also uses vmware, so mac osx or windows 7. i just want the full size of one of the views, but i don't mind, if i need to convert it or just setting the player – Joaolvcm Feb 13 '12 at 12:44
  • Ok, I just tested in MPChc and A .MKV video file I was able to "move Left" in View/Pan&Scan and "zoom" Using the EVR renderer . For the Move or the zoom, if it isnt Keyshorts, it would take a lot of menu clicking. For the Codec, I do have a MKV codec installed, i am not sure if it was needed. VLC has a tendancy to play more formats than MPC without any codec additions to the system. – Psycogeek Feb 13 '12 at 13:53

    VLC doesn't have a 'tendancy' to handle more formats than MPC, it's just that MPC keeps the codecs independant from the player. This is advantageous for a number of reasons. A codec package like CCCP is a much better setup than a single VLC install. – deed02392 Feb 13 '12 at 14:11

Bino 3d, a video player for Windows, OS X and Linux, does exactly what you are looking for. Just select 'left/right, half width' from the input menu and 'left' or 'right' from the output menu.


Regarding VLC, you can use new filter named "wall". It not perfect but easier than @Amit's suggestion.

How to watch 3D SBS in VLC 2.0 and higher

by Tesseract83233 » Mon Sep 10, 2012 12:08 am

The question was:

I got a 3D side-by-side MKV-Movie but I only have a 2D TV - my question was how to get only the picture of the "left eye" in fullscreen with the right aspect ratio?

This is the solution:

And after about an hour of playing around... that's how I solved it:

  1. Start VLC (you don't have to play a video at this time)
  2. Go to "Tools" -> "Preferences" (CTRL+P on Windows)
  3. On the lower left corner choose "Show settings" -> "All"
  4. On the left part of the settings window, scroll down and select "Video"
  5. On the right part of the settings window, scroll down to "Source aspect ratio"
  6. Type in the aspect ratio with the width doubled - for example 32:9 for a 16:9 video, or 8:3 for a 4:3 video...
  7. Click "Save" and exit VLC ---Keep in mind that the changed aspect ratio will be saved for all your videos - remove it after watching 3D or your normal videos might seem to be a bit stretched ---
  8. Start VLC and play your 3D video, pause somewhere at the start
  9. If you don't already know, check your video resolution under "Tools" -> "Media Information" (CTRL+I on Windows) -> "Codec"
  10. Go to "Tools" -> "Effects and Filters" (CTRL+E on Windows)
  11. Go to "Video Effects" -> "Crop"
  12. On "Right" type in the half of your horizontal pixels for example: 1920x1080 ---> 1920/2 = 960 px or: 1280x720 ---> 1280/2 = 640 px
  13. Click on "Close", hit "Play" and enjoy your movie in 2D ;D

If the video feeds are one on top of the other the same applies except double the height (16:9 > 16:18) and crop the bottom by 1080/2 > 540px or 360px.

  • Instead of setting a fixed aspect ratio it is also possible to set a custom list of aspect ratio in the settings, which are then shown in the Video > Aspect Ratio menu – sebix Feb 9 '19 at 16:29

Nvidia 3D vision Video Player will play 3D SBS movies back as a 2D movie. Note that it works only on Windows.


I found this method and its much quicker and easier.

Tools, Effects and filters, Video effect tab, Use the the scroll bar and go right to advanced, check anaglyph 3d

    This only converts the 3d source to anaglyph 3d to watch with red/green glasses. it would call this a solution. – nobs Mar 22 '15 at 19:43
