This recommendation and guidance is meant for a wide audience and may not apply to your production. Please reach out to your Netflix Representative with any questions. 

 

Introduction

The VFX industry has had to pivot quickly from a highly-centralized workforce to a highly-distributed one. This document is a quick reference for platforms and methods which seem to be best serving this dramatic shift in the VFX work paradigm.  The topics mentioned deal more with the logistics of working from home, with the subsequent solutions and practices that are deemed success factors through industry conversations. As a result, please consider this document as organic in nature, with the possibility of change due to evolving solutions and collaborative feedback from our industry partners.  What this document does not try to address are the specific aspects of proprietary pipeline adjustments that may need to be made per studio due to working remotely, which are not necessarily exposed to Netflix.  To be clear, this is not a requirements document, an official endorsement by Netflix of any solutions referred to herein, or a waiver of any contractual requirements or obligations pursuant to a services agreement entered into with Netflix on a specific title. This information is solely provided to engage collaboration and discussion and to share what we know with the vendor ecosystem.

 

While the industry is doing everything it can to keep projects moving forward when possible, our priorities are always guided by the health and safety of our employees and partners. We want to make sure we are all taking the necessary precautions to minimize risk across all of our global productions, VFX facilities, post-facilities, local language vendors, and service providers. We strongly encourage following all recommended health guidelines provided by local governments and health organizations. 

 

The best solution will depend on the specifics of the production and the capabilities of the VFX facility. Please reach out to your VFX Management contact at Netflix for guidance on your specific title(s).

 

Setting Proper Expectations

VFX work from home will have various compromises in comparison to working within a highly-optimized VFX facility. The compromises will vary for each setup and for the range of VFX tasks being addressed.  A general setup for the broad base of VFX artists may be acceptable for a significant amount of the pipeline.  However, for work that is approaching finaling for delivery, the requirements for color accuracy and delivery specifications may require considerations that are more along the lines of Editorial and Color Grading. The Netflix document which addresses these requirements can be found at their respective links.

 

Remote Desktop/Application Control

These solutions require dedicated bandwidth and low-latency connections. The type of solution depends on the type of tasks that the VFX artist is addressing.  For the most part,  products like HP RGS or Teradici have been applied with varying degrees of success by many VFX studios for the majority of departments in their VFX workflows.  Other studios have invested in the infrastructure required to run sessions through Teradici services.  See Remote Desktop Apps Guidance for security best practices.

Remote Reviews/Dailies

We are considering Reviews as an adjunct consideration to the remote workflow for VFX.  This is due to aspects of the reviewing process that might require additional hardware, software licensing, or workflow considerations.  The solutions listed below are by no means an exhaustive list of available products.  They represent the top-of-mind, most commonly deployed solutions that are currently utilized in the industry.  This may change with hardware and application advancements.

 

Solutions

Technical and HD/SDR Reviews

  • CineSync (HD/SDR)
    • Integration with ftrack, Shotgun, and Aspera
      • Playlists generated within Shotgun
    • Python API for integration with other tools
    • Synchronised colour tools
    • Zoom, masking and aspect ratio tools
    • Multiple simultaneous sessions per account

 

SDR/HDR Reviews

  • Streambox (SDR or HDR)
    • Provides a range of products for sending and receiving live video streams, either “one-to-many” using their Cloud offering or “point-to-point” where the devices connect directly to each other. 
    • For SDR review only, our base recommendation is to use the Cloud Encoder and NODE 2 receiver box (Smart TV) or iOS Media Player (iPad Pro).
    • For HDR or any colorist working remotely, our base recommendation is to use the Chroma box solution with a calibrated display.

 

Bandwidth considerations:

  • Cinesync bandwidth requirements for active sessions are very minimal, according to Cospective.  However, since media for dailies need to be transferred prior to the session, please be aware that bandwidth will factor into the physical transfer times. 
  • Streambox: 
    • 20Mb/s for 1080p reviews 
    • 80-100Mb/s for 2160p reviews

 

Additional Guidance (Editorial Best Practices)

 

Displays

This list is not exhaustive, but includes some of the more common displays we recommend for their tier of general use. We always recommend that displays be calibrated to industry standards. Color Grading & Calibration Guidelines provides minimum specifications for HDR and SDR displays as well as calibration and viewing environment guidelines.

 

SDR Displays - Calibrated for Rec.709/BT.1886 at 100-nits

Most of the modern professional and consumer displays are able to meet the standards of SDR color grading. Below are some common displays used for SDR grading/viewing. 

  • SDR (only) Reference Options
    • Sony PVM-A250 
    • Sony BVM-F250
    • Dolby PRM-4220
    • Flanders FSI DM250

* Certain scenarios that use HDR10 signals may require calibration to PQ / Rec. 2020

 

Calibration and Working/Viewing Environment

We understand that having the proper working or viewing environment at home can be difficult to achieve on such short notice. If proper viewing environment guidelines can not be met (Color Grading & Calibration Guidelines) then please make sure the working and viewing environments are not completely dark or extremely bright. A dimly lit environment with neutral (6500K) color temperature is ideal. 

 

Bias Lighting for Home Setups

 

Calibration Probes for Home Setups

Note: The Portrait Displays C6 HDR2000 is only compatible with Calman 2019 R2 and future software releases.

 

Calibration Software

 

Data Management and Custody

Below are guidelines provided by Netflix Studio Information Security on the key aspects for data management and custody.

 

Transferring Content 

Transferring content using home internet services may become a hurdle due to bandwidth limitations. When possible, transferring files via the internet using a secure transfer protocol like Aspera is the best case scenario; Aspera is commonly used by most major facilities as well as Netflix Content Hub.  When bandwidth is limited, the only other option for moving digital assets is using fully disk encrypted hard drives.

 

Secure Network File Transfer (preferred)

  • Content Hub
  • Vendor/Facility offered secure file transfer solution
    • Aspera or Signiant
    • If other please reach out to Netflix's Studio Information Security team (sis@netflix.com) for security guidance.

Physical

  • Fully Encrypted Hard Drives
    • Hardware encryption is preferred and will provide the best performance
    • Software encryption is acceptable but there will be a sacrifice to performance
    • For a short list of drives that meet the Netflix Best Practices requirements  please refer to the Home Studio Security Guidance

 

Working Storage

If a local storage system is used for VFX work, it must also be fully disk encrypted. We recommend Windows Bitlocker or macOS FileVault to encrypt the storage.

 

Data Custody

Please refer to the Storage Policies within the Home Studio Security Guidance doc. Below are some key factors.

  • All disks must be fully disk encrypted 
  • When media is not being used it must be stored in a secure location (safe, locked file cabinet or room, etc.)
  • Once media on temporary storage is no longer needed it must be deleted.

 

Change Log

  • v1.2 - April 1, 2020
    • Release
