Master-Slave Color Grading Hierarchy for Video Trim Pass Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current color grading tools are inefficient and lack creative flexibility, particularly in trim pass operations, as they often require manual manipulation of every frame or shot, and global color grading is insufficient for achieving desired creative outcomes.
Innovation Solution
The method involves designating a master component and associated slave components within video content, allowing for global master grading operations while enabling component-specific slave grading, and prioritizing trim pass operations based on importance metrics to optimize efficiency and creativity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual manipulation of every frame or shot is performed, then creative control is maintained, but time consumption increases significantly
Solution Approach 1:
The patent segments video content into hierarchical components (scenes, shots, frames) and applies color grading at different levels. Master components represent larger segments that can be graded once to affect multiple slave components, reducing redundant operations while maintaining creative control through selective application at different hierarchy levels.
Solution Approach 2:
The patent creates master components that serve multiple functions: they represent a group of slave components for efficient bulk grading, while also allowing individual slave component grading when needed. This multi-functionality enables the same component structure to support both efficient global operations and detailed local adjustments.
2Productivity
If global color grading is applied to all shots, then efficiency is improved, but creative flexibility is reduced
Solution Approach 1:
The patent enables different quality levels of color grading application: master components allow global/ regional grading with uniform properties, while slave components permit local/individual grading with customized properties. This local quality approach ensures that each component receives the appropriate level of attention and customization based on its specific requirements.
Solution Approach 2:
The patent creates a dynamic system where the relationship between master and slave components can be flexibly adjusted. Color grading operations can be applied dynamically at different hierarchy levels, and the system adapts to allow both broad global adjustments and specific local modifications within the same workflow, maintaining creative flexibility while improving efficiency.
3Manufacturing precision
If trim pass operations are performed on every frame, then accuracy is maintained, but processing time increases
Solution Approach 1:
The patent performs preliminary color grading operations on master components before finalizing slave component grading. This preliminary action establishes a baseline grade that can be applied broadly, and then only necessary adjustments are made at the slave component level, reducing the total number of operations required while maintaining accuracy where needed.
Solution Approach 2:
The patent applies color grading operations selectively rather than uniformly to all components. Master components receive full grading treatment, while slave components receive grading only to the extent necessary to achieve the desired result, combining efficient partial action with maintained accuracy in critical areas.

AI summary
Methods and systems for color grading video content are presented. A component (e.g. a frame, a shot and/or a scene) of the video content is designated to be a master component and one or more other components of the video content are designated to be slave components, each slave component associated with the master component. A master component color grading operation is performed to the master component. For each one of the slave components, the master component color grading operation is performed to the slave component and a slave color grading operation that is specific to the one of the slave components is also performed. Metadata, which form part of the video content, are created to provide indicators on to whether components of the video are designated as master or slave components.
