Welcome to the user guide for our Framing and Working Resolution Calculator. This tool can quickly and easily help determine the framing and working resolutions for your project.
For an in depth explanation of working resolution see: "Working Resolution: Considerations & Best Practices."
Netflix is available to assist in navigating production-specific workflow decisions in collaboration with key production stakeholders. Please reach out to your Netflix contacts with any questions or concerns specific to your production.
WHAT IS A “WORKING RESOLUTION?”
Even on a single camera production, multiple resolutions and/or varying aspect ratios will likely be used throughout the production’s lifecycle. The resolution of Original Camera Files (OCF) will likely differ from the resolution that a production frames for on set. The VFX team might ask for a safety area for image repositioning or tracking effects, and a production’s delivery resolution could differ from the final active image resolution.
Establishing a project’s working resolution will help define, clarify, and then simplify scaling needs, unifying different resolutions into a single container resolution from which minimal image scaling operations may be performed during the lifecycle of a project. Furthermore, establishing a working resolution allows for a single scaling operation between OCF and final delivery.
We’ve developed a Framing and Working Resolution Calculator to speed up and simplify the calculations necessary when determining a project’s working resolution.
THE FRAMING & RESOLUTION CALCULATOR
The Framing and Working Resolution Calculator is designed to help productions quickly calculate a Working Resolution and a Minimum Working Resolution. For more on the differences between these resolution types see: “Working Resolution: Considerations and Best Practices.”
To use the calculator, you will simply need the:
- Camera and Sensor Mode
- For more information about cameras that meet Netflix capture requirements see: “Cameras & Image Capture”.
- Lens Squeeze Factor
- For spherical lenses, use 1x.
- Output Aspect Ratio
- This is the aspect ratio of the active image area in the final deliverable.
- For more information on aspect ratios see “Aspect Ratios - An Overview.”
- Safety Crop
- The safety area outside the active image intended for repositioning, tracking effects, or various other uses.
Once these numbers are entered, the calculator outputs information such as the active image resolution, maximum allowed image resize, and whether or not the resolution will be Netflix approved.
Now that you’re familiar with the calculator’s interface, let’s take it for a test drive.
A RESOLUTION RIDDLE
Imagine you're working on a Netflix production that plans to shoot on the Arri LF camera in Open Gate (OG) sensor mode (4448x3096). The Director and Cinematographer want to frame for an aspect ratio of 2.00:1, a different aspect ratio than the OCF. The Director of Photography (DOP) has added a 5% safety area for post processing and the studio requires a UHD IMF at 3840x2160 as the final deliverable.
Try inputting the values from the production yourself:
- Camera and Sensor Mode: Arri LF OG 4.5K
- Lens Squeeze Factor: 1x (for spherical lenses)
- Output Aspect Ratio: 2:1
- Safety Crop: 5%
It’s as simple as that. Based on these variables, this production would ideally use a working resolution of 4044x2814. If however, there are concerns over the amount of data that must be stored, the minimum resolution of 4044x2022 remains an option.
