Encoding
Encoding is the process of digitizing and compressing video and audio assets. Blu-ray supports a multitude of video and audio codecs:
Video |
Audio
(mandatory support) |
Audio
(optional support) |
|---|---|---|
AVC |
Linear PCM |
DTS HD |
VC-1 |
Dolby Digital |
Dolby TrueHD (MLP) |
MPEG-2 |
Dolby Digital Plus |
|
DTS |
||
MPEG |
The disc format, content duration, and content style (i.e., static video, fast camera motion, etc.) will determine the encoding bit rate and the amount of video that can fit on your disc (see charts). Source video must be master quality in HDCAM or HDV tape formats, or a high-definition digital source provided on external HDD storage.
