Multi-View Codec (MVC)
A new video codec based on the Advanced Video Codec (AVC, also known as H.264), called the Multi-View Codec (MVC). Blu-ray 3D discs use MVC video encoding, which provides very high picture quality at a 50% increase in size/bitrate (compared to standard Blu-ray).
While the peak stream for standard Blu-ray movies is 40 Mbps. In the case of Blu-ray 3D, it has increased to 60 Mbps. Blu-ray 3D MVC is encoded as the main video stream (for one eye, i.e. for 2D playback). And an additional (dependent) stream for the other eye. In the second stream, there are references to objects in the frames of the mainstream. That is, only differences are encoded.
Fact about Multi-View Codec (MVC)
- 3D video encoding/decoding in the new version of MPEG-4 is called MVC and is still based on H.264/AVC.
- The MVC format is used both when working with stereoscopic video on Blu-ray 3D discs. And when working with 3D video cameras of the AVCHD standard.
- Despite the same codec name in both cases – MVC, the output files are different. A .M2TS /.SIFF stereo pair on Blu-ray 3D discs and for some reason one single.MTS file for AVCHD 3D video.
- The formal limitation of Full HD quality (1920 x 1080) of progressive scan 24p or interlaced scan 50i/60i recordings. This was in effect for AVCHD versions 1. x and, however, was not respected by almost anyone, was finally removed in version AVCHD 2.0. Finally, 1080@60p/50p scanning for AVCHD is standardized, although, alas, not yet for 3D camcorders.
