Information about 3D

A 3D (three-dimensional) video is a motion picture that enhances the illusion of depth perception. While our software provides customers two solutions to add 3D effect to the output video – Anaglyph and Split Screen.

Anaglyph 3D

Anaglyph 3D were the earliest method of presenting theatrical 3D and it requires less specialized hardware.

In an Anaglyph 3D video, the two images are superimposed in an additive light setting through two filters, for example one red and one cyan. In a subtractive light setting, the two images are printed in the same complementary colors on white paper. Glasses with colored filters in each eye separate the appropriate images by canceling the filter color out and rendering the complementary color black.

To watch the Anaglyph 3D video, what you need is just a pair of archetypical 3D glasses. And you can play the 3D video on the common TV, the common computer monitors, and even the common portable devices

Split Screen 3D

Side by Side 3D - In Side by Side 3D, one frame consists of two halves on the left and right, with the entire frame for the left eye scaled down horizontally to fit the left-half of the frame, and the entire frame for the right eye scaled down horizontally to fit the right side of the frame.

When the 3D ready TV receives this Side by Side 3D signal, it splits each frame to extract the frame for each eye, and then rescales these individual frames to a full HD resolution using upscaling algorithms. It then displays these upscaled individual frames alternately in a frame-sequential manner.

The difference between Side by Side (Half-Width) and Side by Side (Full)

Let's take a 720p (resolution of 1280*720) source video as an example.

If you choose the Side by Side (Half-Width), the output video frame for the left/right eye will be at a 640*720 resolution, and the resolution of the output video will be 1280*720.

If you choose the Side by Side (Full), the output video frame for the left/right eye will be at a 1280*720 resolution, which means the resolution of the output video will be 2560*720. So before you choose the Side by Side (Full) as the output 3D mode, you should check whether the device supports the output video resolution first.

Side by Side (Half-Width) Side by Side (Full)
Resolution of the left eye frame 640*720 1280*720
Resolution of the right eye frame 640*720 1280*720
Resolution of the entire frame 1280*720 2560*720

Top and Bottom 3D - In the Top and Bottom 3D format, one video frame is divided into two sub-frames, the upper one consisting of the sub-frame meant for the left eye and the lower sub-frame meant for the right eye.

And the difference between Top and Bottom (Half-Height) and Top and Bottom (Full) can be largely understood the same as the difference between the two Side by Side modes. The output Top and Bottom (Half-Height) 3D video will keep the resolution of the source video, and the output Top and Bottom (Full) will double the vertical resolution of the original video.

When playing a Side by Side 3D or Top and Bottom video, a 3D PC or 3D TV and the assorted 3D glasses are necessary. But the visual effect of Side by Side 3D and Top and Bottom 3D videos is much better compared to that of Anaglyph 3D video.
