DCP Mastering – File-based Workflow Overview
QuVIS QuStudio provides the tool set necessary to encode or compress source image files that meet DCDM
(Digital Cinema Distribution Master) image specifications (16-bit Uncompressed TIFF, CAP XYZ colorspace) to the
JPEG2000 Digital Cinema standard. Encoded JPEG2000 image and Broadcast Wave audio files are then
transferred to a QuVIS Acuity where the DCP Composition timeline is assembled, edited, previewed and encrypted
(optional). The DCP Composition is then transferred back to QuStudio where all of the assets are packaged and the
DCP is finalized and prepared for distribution. Encrypted content is registered with QuStudio for KDM (Key Delivery
Message) management.
DCP Mastering – Real-time Workflow Overview
The role of the Acuity in the DCP Mastering process varies depending upon the type of DCP Mastering workflow is
employed. If DCP source content can be played as a real-time video stream then the Acuity can be configured to
record that source and perform JPEG2000 image compression (encoding) real-time.
DCP Composition image and audio track assets can be recorded to the Acuity in a couple of ways including as
individual clips that can later be imported into a VTP (DCP) timeline or can be recorded directly into a QuVIS Virtual
Tape. Using the Virtual Tape Editor all of the assets can be edited, previewed and encrypted before the
Composition is finalized and packaged into a DCP.
QuVIS TitleMaster and Output Colorspace Conversion options can be employed to allow preview Subtitle track
assets on a wide variety of display devices including broadcast and production monitors.
QPE content production is popular and the same constructs and workflows that are used to package and distribute
JPEG2000 Digital Cinema content can be used to create QPE Digital Cinema Packages or QDCP. QDCP
packages are only support by QuVIS servers (currently only QuVIS Acuity and QuVIS Cinema Player).
