File-Based Insert Editing for Finalized Multimedia Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-linear editing (NLE) software requires time-consuming and resource-intensive processes for exporting finalized multimedia files, making it inefficient to make changes to source media or modification layers, as the reading and writing processes are separate and cannot locate or replace data within the finalized file effectively.
Innovation Solution
A file-based 'insert edit' system combines reader/decoder and writer/encoder functions to directly manipulate and replace specific data in finalized multimedia files, allowing for frame-accurate editing without modifying the entire file, supporting various multimedia data encoding and container types according to industry standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional NLE software uses separate reading and writing processes for finalized files, then the file structure remains stable and standardized, but editing efficiency deteriorates and requires re-exporting entire files
Solution Approach 1:
The patent merges the reading and writing processes into a unified system where the writing process can directly access and modify specific regions of the finalized file without requiring complete re-export. The writing process incorporates reading capabilities to locate precise insertion points, combining previously separate functions into an integrated editing mechanism that enables direct file manipulation.
Solution Approach 2:
The patent segments the finalized file into identifiable regions and tracks, allowing the writing process to target specific segments for modification without affecting the entire file. This segmentation enables selective editing where only the necessary portions of the file are processed, rather than requiring complete re-export of the entire finalized file.
2Reliability
If conventional NLE software re-exports entire files for any modification, then data integrity is maintained, but resource consumption increases and processing time extends
Solution Approach 1:
The patent applies local quality by maintaining different processing approaches for different parts of the file. The writing process reads and verifies relevant metadata and track information to ensure data integrity at modification points, while avoiding unnecessary processing of unchanged file regions. This localized verification maintains reliability without requiring complete file re-processing.
3Measurement precision
If conventional NLE software cannot locate specific insert points in finalized files, then file compatibility is preserved, but editing precision deteriorates
Solution Approach 1:
The patent performs preliminary actions by reading and analyzing the finalized file structure, metadata, and track information before executing the write operation. This preliminary reading phase identifies precise insertion points, frame boundaries, and track alignments, enabling accurate positioning without requiring complex real-time calculations during the actual write process.
Data Source
AI summary
Techniques are disclosed for non-linear media editing where insert edits are performed directly on finalized digital multimedia files to replace target frames of essence data with new frames of essence data without modifying metadata within the finalized digital multimedia files. Through these techniques, the time-consuming process of re-exporting an edited multimedia file is avoided.
