Auxiliary Archival Assets
The following auxiliary assets are to be included with picture archive assets:

Legal and Illegal Characters
- Legal characters: [ a-z ], [ A-Z ], [ 0-9 ], [ . ], [ _ ], [ - ]
- ILLEGAL: spaces or any other symbols/characters
Folder Structure
DI Assets now have a folder structure which is shorter and concise. Please follow the examples illustrated below:

Folder Naming Examples
DI Assets now have a folder structure which is shorter and concise. Please follow the examples illustrated below:
Episodics:

Features by reel:
Bright/reel_01/dcdm_sdr_xyz/2048x858/File sequence.######.tiff

File Sequence Naming
File names should include the information below separated by underscores:
ProjectTitle_Episode/Reel#_DeliverableName_DynamicRange_ColorSpace
_CreationDate_AspectRatio_Resolution_framenumbers.extension
chefs_table_s01e01_vdm_sdr_rec709_g24_20160430_178_3840x2160.#######.dpx, .tiff, .exr

- For textless or other versioned inserts, reel numbering and frame numbering of textless should match the texted sections, and provide the entire shot.
- Textless end credits do not require a distinct naming convention; they should be submitted alongside the rest of the textless sections.
A framing chart image must be delivered to define the mapping from camera source resolution to final presentation resolution. Specific requirements are listed below:
- A unique framing chart should be supplied for each camera with a unique capture resolution.
- Framing charts should be supplied at the original camera capture resolution.
All output viewing transforms or Look-Up Tables (LUTs) used in color grading must be delivered. LUTs should be delivered .cube format; there is no requirement for LUT dimensions.
File Naming
For a LUT to be useful, it is important that its file name be descriptive as to its application. It must be easy to understand at a glance.

Change Log:
2019-04-12
- Folder and File Naming Structure: Added "GAM" not required for Dynamic Range.
2018-06-19
- Folder Structure: Removed "lp" designation for Longplay content. Requirement to include "Creation Date & Render #" in the folder structure has been removed. Requirements to list "Language version if other than OV" has been removed.
- Folder Naming Examples: Updated to reflect new short/concise folder structure.
- File Naming Examples: Updated to "File Sequence Naming" to provide clarity that guidelines in this section refer to the image sequence itself.
