The Non-Graded Archival Master (NAM) is a fully texted image sequence of the non-color graded, fully conformed and locked picture, including final VFX, rendered in a single scene-referred color space with no output or display transform applied. The archival resolution will be specific to the project and will be communicated by Netflix. At minimum, the archival resolution will be no less than 3840x2160 (UHD) and must include the final delivery active picture area with no cropping, matting or masking applied over the image. If your primary capture format was less than 3840x2160 (UHD) please reach out to your Post Production Management or Creative Technologies Workflow contacts at Netflix to discuss your best options.
The file format of the Non-Graded Archival Master (NAM) will depend on the transfer function of the scene-referred color space as well as the bit-depth of the source files:
*ACES projects must be Linear / AP0, per SMPTE ST 2065-1. ACEScct encoded files will not be accepted.
**10-bit DPX (.dpx) will be accepted only if 50% or greater of the primary capture footage was 10-bit or lower.
Quicktime Wrapped Non-Graded Archival Master Exceptions
Quicktime wrapped compressed formats are acceptable only when 90% or more of the source material originates in a compressed format, such as in the case of Animation. In these cases, the Non-Graded Archival Master must be of equal or higher quality than the original source material.
Acceptable compressed formats:
- ProRes 4444 XQ, DNxHR 444, ProRes 422 HQ.
