Forget Oculus Rift! Google Cardboard is a really cool, yet cheap, VR solution. Along with Google Cardboard 2 Google announced that its SDK was now available to iOS developers, and that the button inside the new headset works with any phone including iPhone 6 Plus. It is an awesome way to use Cardboard for watching movies while laying on your bed paired with a decent set of headphone with your iPhone. This article aims to gives you some tricks for getting 3D Blu-ray movie to Google Cardboard for playing with iPhone 6 Plus correctly.

As far as we know, Google Cardboard lacks ability to play 3D Blu-ray movies, and it requires either Side-by-Side MP4 video. 3D Blu-ray in general acts on the principle of alternating frames for each eye, although there are several methods that can be used. For example, odd-numbered frames might be for the left eye whereas even-numbered frames are for the right eye. Side-by-side 3D means taking each frame, compressing them horizontally, and fitting them in a single frame. This results in the separate left-eye/right-eye 1920×1080 frames becoming two individual 960×1080 images inside the same frame. When you look at these, you can actually see the 3D composite if you use the “relaxed eyes” method.

In this case, we will quickly walk you through how to rip a 3D Blu-ray to Side-by-side 3D file type which is friendly with Google Cardboard, so you can view 3D Blu-ray movies with iPhone 6 Plus in VR Cinema.

Rip and Watch 3D Blu-ray on Google Cardboard via iPhone 6 Plus

Step 1. Load 3D Blu-ray files

Launch the Mac 3D Blu-ray Ripper. Click disc button on the main interface to load your media files to the program. Blu-ray folder, ISO image files are also supported.

Step 2. Select output format

Click on “Format” bar and find “3D Video”, there are a lot of format options for you. Here “MP4 Side-by-Side 3D Video (*.mp4)” is recommended for Google Cardboard.

Tip: Simply click Settings bar and you can tweak the settings to your satisfaction. With the right settings you can retain the quality of the original videos while also saving space.

Note:

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 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.

Step 3. Start converting 3D Blu-ray to Google Cardboard

Finally, hit the “Start conversion” button to start the conversion with the smart 3D Blu-ray to Google Cardboard Converter. It will automatically convert 3D Blu-ray files to Google Cardboard compatible video files with the best quality. After the conversion, click “Open” to quickly find the converted movies.
