Virtual File Structure for Collaborative Video Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current non-linear video editing systems face challenges in collaborative editing, as they often save projects as single monolithic files, making it difficult for multiple editors to work together without overwriting each other's changes and managing permissions effectively.
Innovation Solution
The use of symbolic links and virtualization techniques in a centralized data storage system allows multiple editors to collaborate by creating a virtual file structure where each editor has a unique view of the project, with controlled access and ownership, enabling safe sharing and management of media files across different workstations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple editors open the same Project file simultaneously, then collaborative editing is enabled, but one editor risks overwriting the changes made by another editor
Solution Approach 1:
The patent segments a monolithic Project file into multiple discrete bin files, each representing a separate editable component (e.g., clips, sequences, audio tracks). This segmentation allows different editors to work on different bins simultaneously without conflicts, as each bin can be independently locked or assigned to specific users, thereby enabling collaboration while maintaining data integrity.
Solution Approach 2:
The patent introduces a centralized storage system with file locking and permission management mechanisms as an intermediary between multiple editors and the Project data. This intermediary manages concurrent access by implementing lock protocols that prevent simultaneous writes to the same bin, coordinates editor permissions, and resolves conflicts before they result in data loss, thus enabling safe collaborative editing.
2Device complexity
If Project data is stored in a single monolithic file, then file management is simple, but multiple editors cannot work together without risking overwrites
Solution Approach 1:
The patent divides the monolithic Project file into multiple smaller bin files organized in a hierarchical directory structure. Each bin file represents a logical component (video clips, audio tracks, sequences) that can be independently managed. This segmentation enables multiple editors to work on different bins simultaneously while the centralized storage system maintains overall project coherence, thus achieving both collaboration capability and manageable complexity.
Solution Approach 2:
The patent transitions from a single-dimension monolithic file structure to a multi-dimensional hierarchical file system with multiple bins organized in directories. This dimensional change allows concurrent access from multiple editors while maintaining logical project structure through metadata and indexing, resolving the conflict between simplicity and collaborative capability.
3Reliability
If each editor maintains their own separate Project files, then overwriting risks are eliminated, but collaboration and shared access to media files become difficult
Solution Approach 1:
The patent merges multiple individual editor workspaces into a single centralized storage system where all editors access the same Project and media files through a unified interface. The system implements user-specific bin assignments and permission settings that give each editor their own working environment while maintaining shared access to common assets and sequences, thus achieving both data integrity and collaboration efficiency.
Solution Approach 2:
The patent creates a universal Project structure that serves multiple editors simultaneously through a centralized storage system. The same Project file and media assets can be accessed by multiple users with different permission levels and viewing configurations, enabling one file to serve multiple functions and users without requiring separate copies, thus improving collaboration while maintaining reliability.
4Adaptability or versatility
If a centralized storage system is implemented for collaborative editing, then shared access is enabled, but managing permissions and access control becomes complex
Solution Approach 1:
The patent implements local quality control by assigning different permission levels and access rights to different bins and files within the Project structure. Instead of applying uniform permissions across the entire project, the system allows granular control where specific editors can have read/write access to certain bins while having read-only access to others, thus enabling shared access while managing complexity through localized permission settings.
Solution Approach 2:
The patent enables editors to self-manage their own workspaces by allowing them to create, organize, and manage their own bins and settings within the centralized Project structure. The system provides automatic user profile creation and default permission assignment, reducing the administrative burden while maintaining robust access control, thus achieving shared access with manageable complexity.
Data Source
AI summary
A novel system, method and computer program product for accessing digital media files stored in a media storage device via a server device in communication with the media storage device. The method provides a Project Sharing feature for enabling collaborative sharing of Non Linear Editing (NLE) Projects, even though the NLE application might normally define and save Projects as a single monolithic project file. The system and method provides a file directory and symlink scheme that allows ALL editors who are “members” of a Project Space to see all the bins created by all other editors, but controlling the WRITE ACCESS to the bins according to whose “User Folder” the bins resided in, i.e., a user-based locking scheme is provided to allow control over who can and cannot write to a file. The system and method further treats a single monolithic project file as a collection of smaller Project files, the permissions and ownerships of which could each be controlled independently.
