Cardboard aims at developing accessible virtual reality (VR) tools to allow everyone to enjoy VR in a simple, fun, and natural way. The Virtual Realty Glasses can also turn your Android/iOS smartphone into a very cool 3D/Virtual Reality device. If you are a movie fan, you may look for a way to make it compatible with your Android/iOS devices through Google Cardboard 2.
As we all know, you can use a free app called Cardboard theater, which allows you to enjoy your own 2D and 3D movies in a virtual cinema. And according to official website, Cardboard 2 theater lacks ability to play 3D Blu-ray movies, and it requires supports SBS, Over/Under and Red-Cyan anaglyph formats as well as plain 2D movies in all formats originally supported by your phone. This results in the separate left-eye/right-eye 1920X1080 frames becoming two individual 960X1080 images inside the same frame. When you look at these, you can actually see the 3D composite if you use the "relaxed eyes" method.

How to Copy 3D Blu-ray to Windows Smartphone for Google Cardboard?
Step 1. Import 3D Blu-ray movie
Launch the professional 3D Blu-ray to SBS MP4 converter. Click the button on top left corner to add 3D Blu-ray movie to it. Double click the video, you can preview the movie in the right side.
Step 2: Choose an output format
Google Cardboard 2 can accept 3D SBS MP4 so you can click "Format" bar on the interface then navigate to "3D Video" to choose "MP4 Side-by-Side 3D Video(*.mp4) ". For 3D side-by-side (SBS) movies, please make sure that the filename contains "SBS".
a. The aspect ratio (AR) of a standard Blu-ray frame is 1.77:1. The side-by-side conversion results in the two 3D images getting compressed. In order to show each half image in its original 1.77:1 aspect ratio, we need to cut the vertical resolution in half. For example, the landscape resolution of the iPhone 6 Plus is 1920 x 1080. In order to calculate the correct height, take 1920 and divide it by 3.54. This gives us 1920 width x (1920/3.54) height for a final resolution of roughly 1920 *540.
b. Also, you can freely set the 3D depth as you like to be able to see the entire screen when watching 3D Blu-ray movies. You won't feel as much of a sense of distance going back into your VR headset, but you'll definitely see a difference for objects that are closer to the screen. You can adjust your phone left or right in your Cardboard 2 holder to help to maximize the 3D depth as well as focus the viewing area as closely to the center of the screen as possible. (Learn more).
