QuVIS Acuity and Digital Cinema Content Mastering
QuVIS provides a complete end-to-end solution for the mastering of a DCI JPEG2000 Digital Cinema Package
(DCP) as well as QPE DCPs (QDCP). JPEG2000 Digital Cinema Packages authored using the QuVIS toolset are
interoperable with all industry compliant Digital Cinema playback servers employed for theatrical exhibition
(playback) of Digital Cinema content. QPE Digital Cinema Packages (QDCP) are proprietary and may only be
loaded and played on QuVIS serves (e.g. QuVIS Cinema Player).
In order to facilitate varying file-based and real-time workflow requirements the QuVIS DCP Mastering solution
utilizes a combination of PC-based software tools, QuVIS QuStudio, and real-time mastering hardware available in
the QuVIS Acuity.
QuVIS QuStudio is a computer software application that provides many core functions including:
JPEG2000 image encoding (file-based workflow)
QuStudio provides the commercially licensed KAKADU software engine for encoding Image DCDM (Digital
Cinema Distribution Master) files to the Digital Cinema JPEG2000 image format.
DCP Packaging
QuStudio is used to package completed Digital Cinema Compositions into Digital Cinema Packages
(DCPs) once the project has been assembled, previewed and finalized on a QuVIS Acuity.
Key Management
QuStudio provides key management tools for encrypted compositions.
The QuVIS Acuity mastering server can be used to record Digital Cinema source content in real-time and apply
JPEG2000 image encoding as the input video stream is being recorded. The QuVIS Acuity also combines powerful
composition timeline assembly and editing tools with the ability to preview a composition in its entirety before it is
encrypted and finalized (i.e. packaged).
The QuVIS Virtual Tape (VTP) structure is used to assemble the DCP project timeline. This includes defining the
order of the video, audio and subtitle track files and performing any necessary alignment changes to ensure that the
entire presentation is accurately timed and assembled. The Acuity’s VTP Editor provides a graphical Non-Linear
Editor (NLE) interface for editing the timeline of the DCP project.
Editing a VTP is a non-destructive process, meaning that when an edit is performed on either the VTP video or
audio track the timeline is updated with a new source track file pointer and does not physically overwrite the existing
edit. The VTP Editor provides a session-based ten-layer Undo/Redo mechanism that allows any timeline change to
be easily backed out or reapplied.
The Acuity’s VTR transport buttons and Jog/Shuttle wheel provide real-time playback (QC) of the entire VTP
timeline. This allows the operator to see (video) and hear (audio) the project timeline as changes (i.e. inserting
replacement tracks or segment overlays) are being made. In addition, subtitle file (not spot) placement can be
viewed with fade up/down rendering during playback and jog/shuttle control.
The DCP project timeline does not need to be assembled in one session. In fact portions of the project can be
processed at different times. This can be useful if the project assets (source image or audio files) are not ready at
the same time or if changes need to be made due midstream.
