Thailand Film Dubbing -Content Hub & Physical Archive Media Delivery Specifications Requirements v1.6

We follow what we consider to be the world leader in cutting-edge film production techniques. Netflix. This is because Netflix techniques were designed from the ground up as a digital-technology without any of the legacy that traditional film technology and production houses grew up with. A completely fresh & fully digital approach with a full understanding of current technology provides what we consider the pinnacle of global dubbing processes.

3 Delivery Preparation

3.1 Folder Structure & Naming Conventions

FOR ALL DELIVERABLES:

Legal characters: [ a-z ], [ A-Z ], [ 0-9 ], [ . ], [ _ ], [ - ]

(ILLEGAL: spaces or any other symbols/characters)

3.2 Production Digital Media Assets

The following section applies to productions that are NOT using a Netflix API-integrated dailies solution. Production assets should be prepared by a DMT / DIT according to the following specification. 

→ Root directory: PROJECT TITLE

→ Second-level directory: ASSET TYPE

         OCF - Original Camera Files

         ♦ WAV - Production Sound

         ♦ LOOKS - Any on-set looks (.cdl, .ccc, .edl with CDLs)

         ♦ LUT - Any LUTs used (.cube, .3dl)

         ♦ ALE - Any ALEs generated, with all fields available, including CDL columns if applicable

         ♦ PROXIES - Any proxies recorded or generated, whether at camera or through dailies processing                        (for editorial and/or review)

         ♦ REPORTS - Any data or dailies reports generated

→ Third-level directory: SHOOT DAY & DATE

         ♦ Example:Day_001_20161016

→ Fourth-level directory: CAMERA / SOUND ROLL

OCF Example:

CHEFS_TABLE/

   OCF/

        Day_001_20161016/

            A001CGAL/

            A002DJEU/

Below this folder level, original folder structure and filenames must be maintained from camera or sound cards.

MD5 checksum manifest must accompany all original camera files, stored in the folder of files upon which the checksums are being run, at one of the following directory levels:

Netflix MD5 Checksum and ZIP Tool

For those familiar with Python, Netflix has provided a freely available Python package called the “Netflix Packager” (aka “npack”) that can run MD5 checksums and create the required checksum.txt file. The tool can also ZIP archive the frame sequences in COPY/STORE ONLY mode which is required for Content Hub uploading. Instructions and example command can be found on our Backlot Help center at the following link.

Production Assets Example

3.1.2 Post-Production Assets

3.1.2.1 Editorial Cut Turnovers

Video and edit lists submitted to Content Hub to facilitate review, post-production and distribution work (i.e., work or reference picture, cuts for review and notes) must follow the specifications outlined below.

3.1.2.1.1 Edit List

File type: Edit list should correspond to the video file delivered, in one of the following formats:

3.1.2.1.2 Video File

Resolution: Both vertical and horizontal pixel counts must be integers evenly divisible by 4. It is recommended to encode content at its native aspect ratio, padding with black to the nearest integer evenly divisible by 4.

Frame Rate:

Video/Audio Source Format Specs:

Note: forward slash "/" denotes track separation and comma "," denotes channel separation

3.1.2.2 Editorial Media for Archive

3.1.2.3 Picture Archival Assets

Folder Structure

The first table shows each folder level as a row, along with a corresponding example.

The second table is a legend for the “Deliverable Name” item in red.

pwbh_r01_dcdm_sdr_xyz_g26_20160430_01_textless_3996x2160.#######.tiff

For textless or other versioned inserts, reel numbering and frame numbering of textless should match the texted sections, and be provided cut to cut.

Also, textless end credits do not require a distinct naming convention; they should be submitted alongside the rest of the textless sections.

Full Example

MD5 Checksums

Every directory that contains an image sequence should also contain an MD5 checksum manifest of the files contained within it.

MD5 Checksum Example for Frame Sequences

From within the sequence folder, call the following command to create checksum.txt

find . -type f -maxdepth 1 -exec sh -c "ls -s '{}' | cut -d' ' -f1  | tr  '\n' ' ' " \; -exec md5 -r {} \; | awk '{print $3,"\t",$1,"\t","md5","\t",$2}' > checksum.txt

Example of checksum.txt (note spaces are TABs)

Netflix MD5 Checksum and ZIP Tool

For those familiar with Python, Netflix has provided a freely available Python package called the “Netflix Packager” (aka “npack”) that can run MD5 checksums and create the required checksum.txt file. The tool can also ZIP archive the frame sequences in COPY/STORE ONLY (no compression) mode which is required for Content Hub uploading. Instructions and example command can be found on our Backlot Help center at the following link.

3.1.2.4 LUTs

All LUTs must be delivered in .cube format; we have 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.

LUT Example:

chefs_table_s01_redlogfilm_dragoncolor2_TO_rec709_g24_100nits_FF.cube

3.1.2.5 Servicing Elements

3.1.2.5.1 ProRes Servicing Elements

Resolution: Both vertical and horizontal pixel counts must be integers evenly divisible by 4. It is recommended to encode content at its native aspect ratio, padding with black to the nearest integer evenly divisible by 4.

Frame Rate:

Video/Audio Source Format Specs:

Note: forward slash "/" denotes track separation and comma "," denotes channel separation

ProRes Servicing File Naming
