This newbie’s guide explains what a DCP is, why it is vital, and what independent filmmakers should know before creating one.
What Is a DCP?
A Digital Cinema Package is a set of files specifically designed for playback on professional digital cinema systems.

Before exporting your ultimate audio master, confirm the delivery specifications provided by the venue.
Subtitles and Captions
If your film includes subtitles, these should also be handled accurately throughout DCP creation.
