Something about 3D in General
3D TV might be unofficially dead, but 3D movies are still alive and kicking — particularly with the latest resurgence of virtual reality. 3D technology changes people’s life and make it possible to have an immersed sense when watching 3D movies.
Today let us grasp some more information about 3D. To get any kind of 3D effect, a different image must be delivered to your left and right eye. You can demonstrate this by placing your finger in front of your face and focusing on something behind it. Close one eye, then the other. Observe how the position of your finger changes drastically depending on which eye you’re viewing from. Your brain is constantly combining those two images to give you a 3D picture of the world. In this case, the fact that the finger position changes so much gives it a strong depth clue about how close your finger must be.
The two current methods to do this are called active and passive. Active 3D uses battery-operated shutter glasses that do as their name describes: they rapidly shutter open and closed. Passive uses inexpensive polarized glasses, like what you get at most movie theaters. The TV has a special filter that polarizes each line of pixels. This filter (a Film Patterned Retarder is one type) makes the odd lines on the screen only visible to the left eye, and the even lines only visible to the right. Without the glasses, the TV looks normal.
Active Shutter 3D System
An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images. It works by openly presenting the image intended for the left eye while blocking the right eye’s view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image.
An active shutter 3D system generally uses “liquid crystal shutter glasses” (also called “LCS glasses”, “LCS 3D glasses”, “LC shutter glasses” or “active shutter glasses”. Each eye’s glass contains a liquid crystal layer which has the property of becoming dark when voltage is applied, being otherwise transparent. The glasses are controlled by a timing signal that allows the glasses to alternately darken over one eye, and then the other, in synchronization with the refresh rate of the screen. The timing synchronization to the video equipment may be achieved via a wired signal, or wirelessly by either an infrared, radio frequency, Bluetooth, or optical transmitter. Active 3D provide full 1080p picture resolution for each eye. However, the glasses are expensive and usually bulkier than passive glasses, and some viewers are bothered by their high-speed flickering.
How to copy 3D Blu-ray video
Now, no need to go to the cinema, you can also enjoy active shutter 3D Blu-ray video at home with the help of portable devices or 3D copy software. This guide will teach you how to decrypt a 3D Blu-Ray movie and make a copy of it with 3D effect preserving using an active shutter 3D copy software.
First of all, download and install Leawo Blu-ray Copy to your PC. After installing the program and launch it, its neat interface gives you a deep impression. The friendly step-by-step layout will display as follows:
Step 1. Insert Blu ray disc into BD drive and launch the program.

Step 3. Define copy settings
Choose copy mode and select output disc type at the bottom left. Click the big green “Copy” button. Three types of copy mode will display. If you choose the main mode, it will only copy the main 3D movie and remove menus and other unnecessary special functions.
If you can tick the “custom mode”, it allows you to define what chapters, subtitle and audio you want to back up. Moreover, you can choose the custom chapters comfortably with a preview function.
Step 4. Start to copy
Before you click “start” button, please check out all your settings are right. Set “Copy to”, “Disc Label” and “Save to” options. Make sure you have enough hard drive space. Once all are ok, start to copy 3D Bluray movies from BD disc. The process of duplication needs little system resource.
By the way, Leawo Blu-ray Copy can compress BD-50 to BD-25 with an outstanding output quality. After duplication, open output file destination, locate the created 3D video and you could watch it on your 3D player as you want.
The program is a highly-rated Blu-ray copy software on the market and available for Windows and Mac users. Leawo Blu-ray Copy comes with all features that we could expect from a “Pro” level Blu-ray copy software.
