Introduction
This page contains some general information about digital cinema content.
Picture
The picture steam is a sequence of JPEG 20000 images, encased in an mxf wrapper. The standard pixel dimensions are:
| Name | Dimensions | Ratio |
|---|---|---|
| Full | 2048 x 1080 | 1.90:1 |
| Scope | 2048 x 858 | 2.39:1 |
| Flat / X-Wide | 1998 x 1080 | 1.85:1 |
| Wide | 1920 x 1080 | 1.78:1 |
Content of any pixel dimensions can be played, however the projector will not perform any scaling; content will be clipped or black bars will be added as necessary.
Sound
The sound stream consists of a single uncompressed pcm file (usually a Windows .wav file) for each audio channel. These, like the picture steam, are encased in an mxf wrapper.
