Digital Cinema Naming Convention

Appendix #3

 

Content Type and Version Number      The Content Type and Version field is the area of the Naming Convention that identifies what type of content the DCP contains -- whether it's a feature, a trailer, a short subject, etc. -- and what the version number is.  The field can contain up to 7 characters.  All content should be categorized as one of the following:

FTR = Feature

TLR = Trailer

TSR = Teaser

PRO = Promo

This should be used for all non-trailer promos such as those shown at CinemaCon or CineEurope.

TST = Test

(Framing and/or color charts, etc.)

RTG = Rating Tag

("RTG" should be followed by either "-F" for feature or "-T" for trailer)

SHR = Short Subject

ADV = Advertisement

All commercials, including music videos.

XSN = Transitional

(Includes Digital Black for spacing as well as "Put Your 3D Glasses On Now" cards.)

PSA = Public Service Announcement

(Charity trailers.)

POL = Policy Trailer

("Turn off cell phones", etc.)

 

 It's important to add a version number after the Content Type code.  For example, feature version 2 would be "FTR-2", etc.  This is important not only for selecting the correct version, but also for matching an "OV" with a "VF" version file.  (See Appendix #8.)  The Content Type field can also be expanded to add 2D or 3D identifiers.  (See Appendix #3a.)

 

Temp

This means the picture and/or sound are temporary and unfinished:  such as a preview or rough-cut version etc.  This is to prevent this version from accidently being distributed to theatres as the "final release".  If the picture and sound are final, you would simply leave the word "Temp" off.

Pre

If the picture and sound are final, but the Package is a "Pre-Release" package without Accessibility features such as HI or VI, you may use the Descriptor:  "Pre" to indicate that it is pre-release.  If the picture is final and includes those Accessibility features that you intend to include in the wide release, then you would simply leave the word "Pre" off.

RedBand

For US released trailers, NATO and the MPAA have requested that trailers with the Red Band MPAA rating be clearly marked early in the DCP file name.  This is so theatres will more clearly see the trailer is restricted, and not accidently place a Red Band trailer with a G, PG, or PG-13 movie.  The trailer rating will still also be mentioned in the Territory/Rating Field as:  "US-RB".

CHAIN

Many Promos or Trailers (especially Policy Trailers) are designed for specific Theatre Chains or Events.  This sub-field is where to name the specific theatre chain or event.  For example:  "MovieTitle_Pro-1-Cannes" would be the Cannes Film Festival Promo #1 for this movie.

Occasionally, several theatre chains want the same "Special" version of a trailer.  You have the option of using the word "ALT" in the theatre chain sub-field instead of naming a specific theatre chain.

For example, suppose "Grand Cinemas" wants your Trailer # 1 except without a certain Giant Screen Logo at the end because they have their own giant screen brand.  You could call this version:

MovieTitle_TLR-1-GrandCinemas etc.

But if several different theatre chains want the same exact trailer without the well-known Giant Screen Logo, you would have the option of creating a single DCP with the word "ALT" instead:

MovieTitle_TLR-1-ALT

This makes the DCP a generic alternative to TLR 1.

It is up to the studios to communicate to theatres what "ALT" signifies.

3D or 2D

If the product is 3D, say it here.  If the product is in both 2D and 3D, label the 2D version:  "2D" and the 3D version:  "3D".  If the product only exists in 2D, you do not need to label it "2D"; it will be assumed to be in 2D if it is not otherwise described.

4fl

There is currently no luminance standard for mastering 3D Digital Cinema Content.  Some films are color timed at 3.5 foot lamberts, others at 4, 4.5, 6, 7, and even 10 foot lamberts.  If you have multiple luminance versions of your product, put the foot lamberts here in order to signal which version the DCP contains.  Do not use decimal points.

48

Frame Rate.  (If other than 24 frames per second.)

 

In the Composition Playlist

The Chain is listed at //Reel[1]//Chain:

     ...

     <Chain>Grand Cinemas</Chain>

The Luminance is listed at //Reel[1]/Luminance:

<CompositionMetadataAsset>

     ...

     <Luminance units="foot-lambert">3.5</Luminance>

</CompositionMetadataAsset>


2D content is identified by the presence of the MainPicture element, which is listed at //Reel//MainPicture[1]:

<Reel>

     ...

     <MainPicture>...</MainPicture>

     ...

</Reel>


3D content is identified by the presence of the MainStereoscopicPicture element, which is listed at //Reel//MainStereoscopicPicture[1]:

<Reel xmlns:msp-cpl=”http://www.smpte-ra.org/schemas/429-10/2008/Main-Stereo-Picture-CPL”>

     ...

     <msp-cpl:MainStereoscopicPicture>...</msp-cpl:MainStereoscopicPicture>

     ...

</Reel>


The Frame Rate is listed at //Reel//MainPicture[1]/FrameRate or //Reel//MainStereoscopicPicture[1]/FrameRate:

<Reel>

     ...

     <MainPicture>

          <FrameRate>48 1</FrameRate>

     </MainPicture>

     ...

</Reel>


Additional Notes:

     1) The MainPicture and MainStereoScopicPicture elements are mutually exclusive: both may not appear within the same reel.

     2) The MainStereoScopicPicture element is described in the SMPTE 429-10 standard.


In the Composition Playlist

The Content Type is listed at //ContentKind:

<CompositionPlaylist>

     xmlns="http://www.smpte-ra.org/schemas/429-7/2006/CPL">

     ...

     <ContentKind>feature</ContentKind>

     ...

</CompositionPlaylist>


Additional Notes:

     If the scope attribute is absent, the permissible SMPTE 429-7 ContentKind values are as follows: "feature", "trailer", "teaser", "promo", "test", "rating", "advertisement", "short", "transitional", "psa", and "policy".  See the specification for details.

In the Composition Playlist

The Version Number is listed at //Reel[1]//VersionNumber:

<CompositionMetadataAsset>

     xmlns="http://www.smpte-ra.org/schemas/429-16/2014/CPL-Metadata">

     ...

     <VersionNumber status="final">2</VersionNumber>

     ...

</CompositionMetadataAsset>


Additional Notes:

     1) The status attribute of the version number should have one of the following values: "final", "temp", or "pre".

     2) The VersionNumber element of the Composition Metatdata Asset is preferred over the ContenVersion element of the Composition Playlist.  The latter element is more suitable for registry-based identifiers such as EIDR.


     After the Content Type and Version number in the Content Type Field, you may add further descriptions or "Content Type Modifiers" in sub-fields separated by hyphens.

For example:  POL-1-Temp-RedBand-TheatreChain-3D-6fl-48

 

These are used "a la carte" only if needed, and must be used in this order with these words:
