Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video editing systems cache a fixed number of frames per video material, leading to inefficient memory usage and stuck video clipping processes when handling multiple video materials, resulting in low editing efficiency.
Innovation Solution
A video processing method that determines cache priorities for video track segments based on their location in the display area and timeline range, allowing flexible caching and optimizing memory usage by prioritizing frames for caching based on their visibility and importance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed number of video frames are cached per video material according to preset configuration, then the caching process is simple to implement, but the memory occupation increases significantly when handling multiple video materials, causing the video clipping process to stall and reducing editing efficiency
Solution Approach 1:
The patent changes the caching parameter from a fixed preset number to a dynamic value determined by actual needs. Specifically, it calculates the required cache size based on the number of video materials being edited and the display area requirements, transforming the caching strategy from static to adaptive, thereby resolving the contradiction between implementation simplicity and editing efficiency
Solution Approach 2:
The patent introduces dynamic adjustment mechanisms for video frame caching. The cache size and priority are dynamically determined based on real-time factors such as the number of video materials, display area occupancy, and editing progress, allowing the system to adapt to changing editing scenarios and avoid memory overflow while maintaining high clipping efficiency
2Ease of operation
If a fixed number of video frames are cached per video material, then the caching strategy is easy to manage, but the memory usage becomes excessive when editing multiple video materials, leading to process stagnation
Solution Approach 1:
The patent transforms the caching parameter from a fixed preset value to a dynamically calculated value based on actual editing needs. The system determines the optimal cache size by considering the number of video materials and their display requirements, changing the parameter from static to adaptive to reduce unnecessary memory occupation while maintaining ease of management through automated calculation
Solution Approach 2:
The patent performs preliminary calculation of cache requirements before actual caching occurs. By pre-determining the appropriate cache size based on the number of video materials and display area needs, the system avoids excessive memory allocation while ensuring sufficient cache space is available, thus preventing process stagnation without complicating management
3Adaptability or versatility
If more video materials are edited simultaneously, then the video editing capability is enhanced, but the memory occupation increases causing the clipping process to get stuck
Solution Approach 1:
The patent introduces dynamic cache management that automatically adjusts to the number of video materials being edited. The system calculates and adjusts cache allocation based on real-time editing conditions, ensuring that sufficient resources are allocated to maintain stable clipping processes while supporting the editing of multiple video materials simultaneously, thus enhancing versatility without compromising reliability
