Color Management in DaVinci Resolve and ACES

Overview

  • Focus on color management in DaVinci Resolve and ACES.
  • Key differentiation between display-referred grading and scene-referred grading.
  • Suitable for beginners, with timestamps for advanced users.

Basic Concepts

Display-referred Grading vs Scene-referred Grading

  • Display-referred Grading:

    • Directly adjust image to improve appearance based on monitor display.
    • Typically involves adjusting lift and gain to enhance contrast and saturation.
    • Suitable for outputs like web and broadcast.
  • Scene-referred Grading:

    • Utilizes camera manufacturer's technical specs to establish a better starting point.
    • More technically accurate; involves using LUTs for correct color mapping.
    • Example: using AR Alexa LUT to transform log footage to Rec 709.

Using DaVinci Resolve Color Management

  • Color Space Transform:
    • Allows users to set input and output color spaces.
    • Input example: AR Wide Gamma 3, Output example: Rec 709.
    • Ensures images are in a technically correct color space before grading.

Steps for Color Management in DaVinci Resolve

  1. Create versions for testing adjustments.
  2. Use Color Space Transform to apply camera-specific specs.
  3. Copy settings across shots for consistent starting points.
  4. Customize timeline color space for better grading efficiency.

Working with ACES

Overview of ACES

  • ACES standardizes color management across various platforms.
  • Supports a large color space (AP0) and dynamic range.
  • Utilizes input device transforms (IDTs) to correctly interpret camera footage.
    • Example IDTs include AR log C, Red log 3G10, etc.

Working Process in ACES

  • Clips are processed through AP0 to AP1 to be used for grading.
  • Input Device Transform is essential for accurate color representation.
  • Final output can be easily transformed to various delivery formats (Rec 709, P3, HDR).

Comparison of ACES and Resolve Color Management

  • ACES:

    • Industry standard; better interoperability between platforms.
    • Open source; recommended for broadcasting platforms like Netflix.
    • Fewer options, easier for beginners.
  • Resolve Color Management:

    • More customizable and scalable for advanced users.
    • Offers flexibility in managing color spaces and tone mapping.
    • Provides a familiar feel for users accustomed to Resolve.

Practical Tips for Beginners

  • If unsure about source material, check file names or consult the production team.
  • Experiment with various input transforms if the source is unknown.
  • Use Rec 709 scene settings when dealing with stock footage or graded clips.

Conclusion

  • Understanding color management is essential for effective grading in DaVinci Resolve.
  • Both ACES and Resolve color management offer unique benefits based on project needs.
