![]() You may find more detailed information of Active shutter 3D on Wikipedia. It uses a pair of liquid crystal shutter glasses to watch, and can be applied to present 3D images on various types of displays, namely, LCD, Plasma TV, CRT, projectors, etc. ![]() You may get more detailed information of Anaglyph 3D on Wikipedia.Īctive shutter 3D: it is a technique of displaying stereoscopic 3D images, which works by presenting the image to the one eye which blocking the other eye and repeating that interruptions rapidly. As a result, what you get is a seriously distorted and quality degraded 2D video.ģD video system is divided into 3 different types: anaglyph 3D, active shutter 3D, and polarized 3D.Īnaglyph 3D: it is the earliest approach to present theatrical 3D, and this 3D media needs a pair of red and greenish-blue (cyan) glasses to watch. Another point is that the simple and quick cropping sometimes cuts the frames inaccurately. ![]() After cropped, the square frames need to stretch to fill up the screen which is at the aspect ratio of 16:9 or 4:3. However, the cropped frames turn out to be square by simply cutting a half of the original 3D frames. ![]() The basic way to divide 3D frames is to crop the images, which is also employed by VLC to convert 3D videos to 2D. ![]() In the process of a 3D video conversion, the biggest challenge is to separate the frames shot from 2 perspectives without any distortion. In this way, a regular motion picture camera system is employed to record the images as seen from two perspectives and a special projection or eyewear is used to limit the visibility of each image to the watcher's left or right eye exclusively. The most common way to produce a 3D video originates from stereoscopic photography. In simple words, 3D video stands for three-dimensional video which offers a stereoscopic image by enhancing the illusion of depth perception to add a third dimension. ![]()
