Editing Apparatus for Seamless Video File Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional editing methods for video data stored in multiple files cause image deterioration at connection points due to interframe coding, making it difficult to integrate files seamlessly without proper frame referencing.
Innovation Solution
An editing apparatus and method that determines the generation order of multiple files with interframe coded data and integrates them in that order, allowing for seamless connection and editing without image deterioration, by using a determination unit and integration unit to arrange and combine files as a single virtual clip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If video data corresponding to one shot is stored as multiple files due to file size limits, then the storage medium can accommodate the data, but image deterioration occurs at connection points between files during editing
Solution Approach 1:
The video data of one shot is segmented into multiple files based on file size limits, with each file containing a portion of the interframe coded data. The system manages these segmented files through determination units that identify generation order and integration units that combine them, resolving the contradiction between storage capacity and image quality at connection points.
Solution Approach 2:
The patent introduces determination units and integration units as intermediary components that manage the connection between multiple files. These units ensure proper inter-frame referencing across file boundaries, preventing image deterioration at connection points while maintaining the ability to store large volumes of video data as multiple files.
2Manufacturing precision
If a file system with large maximum file size is used to store one shot as a single file, then image deterioration is avoided, but the file system becomes complex and OS-specific
Solution Approach 1:
The patent creates a universal file management system that works with conventional OS and standard file systems. By using determination units to identify generation order and integration units to combine files, the system achieves single-file-like editing capabilities without requiring a complex, OS-specific file system structure, thus maintaining compatibility while avoiding image deterioration.
Solution Approach 2:
The determination and integration units act as intermediaries between the conventional file system and the editing process. They enable the system to treat multiple files as a unified entity for editing purposes, achieving the benefits of large file storage without actually requiring a complex file system structure.
3Ease of operation
If multiple files are edited without proper integration, then editing flexibility is maintained, but inter-frame references cannot be performed properly causing image deterioration
Solution Approach 1:
The determination units identify the generation order of multiple files, and integration units combine them with proper inter-frame referencing. This intermediary processing maintains editing flexibility by allowing editors to work with multiple files while ensuring proper image quality at connection points through automated integration.
Solution Approach 2:
The patent replaces the manual mechanical process of ensuring proper frame referencing with an automated determination and integration system. The determination units automatically identify generation order, and integration units handle the complex inter-frame referencing, substituting manual operations with automated processing that ensures image quality.
