Change Full SBS 3D to Half SBS 3D Video

SBS 3D, short for side-by-side 3D (left and right 3D), is a popular choice and widely used 3D format besides frame-sequential 3D when it comes to airing 3D content over 3D TV, video protjector or VR headset. SBS 3D can be divided into Full SBS 3D and Half SBS. Many people have some Full SBS 3D video and want to convert the Full SBS video to HSBS videos. So what's the difference between Half SBS and Full SBS? And how to get the Full SBS 3D to Half SBS 3D conversion?

Half SBS and Full SBS: Explain The Difference

Half Side-by-Side (SBS), means the left and right views of a 3D video are subsampled at half resolution and you get a backwards compatible full frame.

Example: Say, each view is 1920×1080

subsample to 960 x 1080, put them side by side and now you have a 3D 1920×1080 frame.

Full SBS, means you transmit both views at full resolution; better quality, but bigger file.

The half-SBS was the necessary format for YouTube 3D, until it added the capability for half OU: half Over and Under. This is superior for 3D stereo perception because the full HD horizontal resolution is retained, and the vertical resolution is interlaced between right and left, adding up to a perception of fuller resolution than the actual halving would suggest.

For Example:

Half-SBS = (960+960) 1920 x 1080P
Full-SBS = (1920+1920) 3840 x 1080P

3DBD Bluray 1920 x 1080 Left + 1920 x 1080 Right,
= 3840 x 1080 Full-SBS, but Only can be played
from BD/ BD25/ BD50 via Bluray Player

Now with Passive TV's in 2D they are Full HD 1920 x1080P
In 3D because of the Polarized Glasses you only see,
Half the Horizontal Res of Left Eye and Half for Right Eye 540P

Half-SBS on Passive is 960 x 540 (Left) + 960 x 540 (Right)
Half-SBS on Active is 960 x 1080P (Left) + 960 x 1080P (Right)

Full Over/Under (aka) Top & Bottom
Full – 1920 x (1080+1080) 2160
Half – 1920 x (540+540) 1080P
