Solution Overview
Problem
Existing video editing technologies require significant human intervention and computing resources, are difficult to master, and cannot efficiently implement user-desired video effects like freezing frames, leading to inefficient resource usage and limited editing capabilities.
Innovation Solution
Implement a method and apparatus for video editing that involves determining a single-frame processing policy and a video post-processing policy based on user selection, performing single-frame processing, caching results, and forming a video editing sequence to reduce operational difficulty and computing resource usage, enabling more complex effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional single-frame processing mode is used for video editing algorithm, then processing simplicity is maintained, but computing resources are wasted due to repeated invocation at different time nodes
Solution Approach 1:
The patent performs video editing algorithm inference in advance for all frames before user editing operations, caching the results. When users switch between time nodes, the pre-computed results are directly applied without re-invoking the algorithm, thereby eliminating repeated computing resource consumption while maintaining operational simplicity.
2Extent of automation
If intelligent video editing algorithm is adopted, then automation is improved, but computing resources are excessively consumed due to multiple frame processing requirements
Solution Approach 1:
The system performs the computationally intensive video editing algorithm inference once in advance for all frames, storing the results in a cache. This preliminary action maintains full automation capability while avoiding repeated computation when users navigate between different time nodes, thus reducing overall computing resource consumption.
Solution Approach 2:
The patent creates a cached copy of the video editing algorithm inference results for each frame. Instead of re-computing when users access different time nodes, the system directly utilizes these pre-generated copies, thereby maintaining automation while significantly reducing computing resource usage during user interactions.
3Manufacturing precision
If video editors with human involvement are used, then editing precision is maintained, but operation difficulty increases making them hard to master
Solution Approach 1:
The patent implements intelligent video editing that automatically performs editing operations based on user-selected time nodes and desired effects. The system self-executes the video editing algorithm without requiring manual frame-by-frame adjustment, thereby maintaining editing precision through algorithmic consistency while dramatically reducing operation difficulty for users.
4Adaptability or versatility
If multiple frames are cached for video editing, then editing capability is improved, but memory consumption increases
Solution Approach 1:
The patent extracts only the essential processing results from the video editing algorithm inference and caches them in a structured format. By taking out only the necessary information needed for subsequent editing operations rather than caching complete frame data, the system improves editing capability while controlling memory consumption through selective extraction and storage of critical processing outcomes.
