Folder Naming Examples

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

chefs_table_s01e01/vdm_dolby_hdr/3840x2160/File sequence.######.tiff

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

Features longplay:
NOTE: No title folder needed
vdm_dolby_hdr/3840x2160/File sequence.######.tiff



File Sequence Naming

File names should include the information below separated by underscores:


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.



Framing Charts

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. 



Viewing Transforms

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.

  • 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.
