Video Formats
The following lists the video formats that are suitable for a DCP:
If your source material is in a different aspect ratio than the ones de-
tailed above, the material should be scaled for the digital cinema output
so that it fits either vertically or horizontally in one of the ’full’ formats
(thereby applying either letter- or pillarboxing).
Audio Formats and Mapping
Audio should be saved in 24 bit at 48,000 Hz and the DCI specification
suggests the WAV file format. For a DCI Mastering the routing of the
audio tracks containing the audio data must be adapted as outlined in
SMPTE 428-3 in the CLIPSTER Edit Tool. The table below shows map-
ping and labels suitable for audio in a DCP (quoted from the specifica-
tion for nine channels):
