SBS: If the video is taken with settings that enable 3D, the MP4 will be encoded in SBS (Side by Side) format, which is a 3D filetype where one video per eye is encoded side by side, the left eye on the left, and the right eye on the right. These files will automatically be detected on Leia devices as 3D videos. They may be backwards compatible with other 3D devices, but may require extra filename tagging or manual option selection to show the file in 3D. On 2D devices, you will be able to play back the SBS file, however you will see both the left and right eye video on the screen at the same time.
