Best 3D Video Converter to Convert Video to 3D and 2D Format

Since the movie Avatar shot and played in 3D hit the bull's eye, 3D technology has been more and more popular in video making. It enriches audiences' visual experiences compared to common 2D videos. However, to enjoy a 3D video at home is not a fantasy without 3D glasses or 3D players, thus you need to convert it to 2D format. On the other hand, some people want to create 3D videos from 2D like professionals. Take both situations into consideration, we picked up the best video converters that can convert either 3D to 2D or 2D to 3D. Read this post and surely you'll find more.

Quick Navigation:

Part 1. What is 3D Video?

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. The most common way to produce a 3D video originates from stereoscopic photography. 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. Then a stereoscopic image turns up.

In the process of a 3D video conversion, the biggest challenge is to separate the frames shot from 2 perspectives without any distortion. The basic way to divide 3D frames is to crop the images, which is also employed by VLC to convert 3D videos to 2D. However, the cropped frames turn out to be square by simply cutting a half of the original 3D frames. 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. Another point is that the simple and quick cropping sometimes cuts the frames inaccurately. As a result, what you get is a seriously distorted and quality degraded 2D video.

3D Video

3D video system is divided into 3 different types: anaglyph 3D, active shutter 3D, and polarized 3D.

Anaglyph 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.
You may get more detailed information of Anaglyph 3D on Wikipedia.

Active 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. 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 find more detailed information of Active shutter 3D on Wikipedia.

Polarized 3D: this 3D system uses polarization glasses to create an illusion of a 3D image. There are two types of polarized glasses: linearly polarized glasses and circularly polarized glasses, and this is how it works: two images are projected onto the glasses which contain two polarizing filters. Each filter passes only that similarly polarized light and blocks the other light. By restricting the light that reaches each eye, each eye sees a polarized image.
You can have more detailed information on Polarized 3D on Wikipedia.
