Making a DCNC DCP name

The ISDCF DCNC (Digital Cinema Naming Convention)

When creating DCPs, it’s crucial to avoid whitespaces and special characters in filenames to ensure compatibility across different playback systems. Rather than using casual names like ‘My Super Movie,’ industry professionals follow the ISDCF DCNC (Digital cinema naming convention) . Here’s an example:

MovieTitle_FTR_F_EN-XX_INT_51_2K_NULL_20230622_NUL_SMPTE_OV

Understanding DCNC Components:

  • Each DCP must include all required fields to pass validation tests
  • When no studio code or distributor code is available, use ‘NULL’ as a placeholder
  • The DCNC name applies to multiple elements:
    • The DCP folder
    • Content title
    • PKL (Packing List)
    • CPL (Composition Playlist) annotation text

Important Note: The content title using DCNC format will be displayed on cinema playback systems.

Special Case for Multiple CPL DCPs:
When dealing with DCPs containing multiple CPLs, there are two options for PKL naming:

  1. Use the primary CPL name
  2. Create a descriptive PKL name that encompasses all CPLs

This standardized naming convention ensures compatibility and proper identification across the digital cinema ecosystem.

Making a DCNC name

Title

MovieTitle

The title portion of a DCP name must follow specific formatting rules:

Character Limit

  • Maximum 15 characters
  • Includes letters and numbers only
  • No spaces or special characters allowed

Formatting Rules

  • Use CamelCase (capitalize first letter of each word)
    Example: BigHero6, FastFive, TheMatrix

Long Title Handling

  • For titles exceeding 15 characters, use the beginning portion
    Original: “The Incredible Journey”
    DCNC: “TheIncredible”

Remake Identification

  • Include release year for movie remakes
    Example: King Kong (2005) could be “KingKong2005”

Content Type

FTR

  1. Basic Requirements
    • Content Type must match the DCP’s Content Kind setting
    • Example: FTR designation requires “feature” Content Kind
  2. Version Numbering
    • Add numbers for multiple versions
    • Format: [Type]-[Number]
    • Example: FTR-7

Common Applications:

  • Feature Films: FTR
  • Movie Trailers: TLR
  • Festival Short Films: SHR

Version Management
Original Version (OV) and Version File (VF) Correlation:

  • OV and corresponding VF must share the same version number
  • Example:
  • Original: FTR-7 (OV)
  • Supplemental: FTR-7 (VF)

Creating Unique Identifiers
To distinguish between versions, modify:

  • Date code
  • Version number
  • Or both elements

Best Practices:

  1. Always verify Content Type matches Content Kind
  2. Maintain consistent numbering between OV and VF

Content Type matches the Content kind set on the DCP. So FTR must match Content Kind “feature”.

Aspect Ratio

F

Standard Cinema Aspect Ratios

  • Flat (F): 1.85:1
  • Scope (S): 2.39:1
    These are universally supported by all cinema projection systems.

Handling Non-Standard Aspect Ratios
Films often come in various aspect ratios:

  • 1.33:1 (Academy)
  • 1.66:1 (European standard)
  • 1.78:1 (16:9)
  • 2.00:1
  • 2.20:1

Container Format Naming Convention
Non-standard aspect ratios must be packaged within either Flat or Scope containers. The naming convention uses the following format:

  • [Container]-[Aspect Ratio]
    Examples:
  • F-133: 1.33:1 within Flat container
  • F-200: 2.00:1 within Flat container
  • S-266: 2.66:1 within Scope container
  • F-190: 1.90:1 within Flat container

Important Notes:

  • The Full Container (C) format is not recommended
  • DCPs created in C format typically display in Flat with potential cropping

Trailer Specifications

Trailers are produced in both Flat and Scope versions

They use only F or S designations regardless of internal black bars

This ensures proper projection and masking to match their accompanying feature films

Language

EN-XX

Language Code Basics

  • EN: English dialogue
  • XX: No subtitles present
  • [Primary Language]-[Subtitle Language]: Format for subtitled content

Examples:

  • EN-XX: English dialogue, no subtitles
  • EN-NO: English dialogue with Norwegian subtitles
  • FR-EN: French dialogue with English subtitles

Subtitle Format Indicators
The case of the subtitle language code indicates the subtitle type:

  • UPPERCASE (EN-NO): Soft-coded subtitles (XML/MXF format)
  • Can be turned on/off
  • Separate file from the image
  • lowercase (EN-no): Hard-coded subtitles
  • Burned into the image
  • Cannot be disabled

Multiple Language Content

  • For films with multiple spoken languages, use the predominant language as the primary code
  • Example: A film primarily in English with some French dialogue would use EN as the primary code

Pro Tip: Always verify the correct language codes from the official ISDCF DCNC documentation when preparing your DCP.

Territory/Rating

INT

Rating and Territory Codes
These standardized codes, defined by the ISDCF Digital Cinema Naming Convention (DCNC), indicate a film’s rating and intended territory.

Common Examples:

  • UK-12A: United Kingdom, rated 12A
  • INT: International version (suitable for all territories)
  • INT-TD: International version with text elements (credits, signs, etc.)
  • INT-TL: International version without text elements (textless)

When to Use Each Code:

International Versions
• INT: Standard international version
• INT-TD: Use for versions with burned-in text elements
• INT-TL: Use for clean versions without text elements (useful for localization)

Territory-Specific Ratings
• Use when the DCP is for a specific country with a defined rating
• Example: US-R, DE-12, NO-15

Audio

51: 5.1 surround sound

Most common format for Original Version (OV) DCPs

Consists of: Left, Right, Center, LFE (subwoofer), Left Surround, Right Surround

Advanced Audio Formats

    • Different audio formats (5.1 to 7.1)
    • Enhanced sound (Dolby Atmos)
    • Alternative aspect ratios

Version Management:

  • OV and related VFs should maintain consistent naming conventions
  • Version numbers should correlate between OV and VF
