Proxy Video Transmission with Metadata Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video production faces challenges such as time constraints, budget limitations, and the complexity of transferring high-resolution video files, particularly over long distances with limited wireless coverage, which can result in errors, delays, and compromised quality.
Innovation Solution
A system that extracts metadata from high-resolution video files and transmits lower-resolution proxy files via a high-bandwidth channel, such as Wi-Fi or Ethernet, allowing for seamless editing and using bonded cellular networks for reliable transmission, eliminating the need for physical media and reducing data loss risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution video files are transmitted over long distances with limited wireless coverage, then video quality is maintained, but transmission reliability deteriorates and errors increase
Solution Approach 1:
The system segments video transmission into two parts: proxy video files (lower resolution) are transmitted wirelessly for immediate editing, while original high-resolution video files are stored locally or on physical media. This segmentation allows editors to work with proxy files over unreliable wireless connections while preserving the ability to access high-quality originals when needed.
Solution Approach 2:
Proxy video files serve as an intermediary between the shooting location and the editing process. These lower-resolution files can be transmitted over limited wireless coverage areas, enabling editors to access and work with video content without requiring direct access to the original high-resolution files or being present at the shooting location.
2Manufacturing precision
If original high-resolution video files are transmitted, then video quality is maintained, but data loss risks increase due to errors and delays
Solution Approach 1:
The system creates proxy copies of the original video files at lower resolution. These proxy copies contain all necessary metadata and are sufficient for the editing process. By working with copies rather than originals during transmission, the risk of data loss to the original high-resolution files is eliminated while still enabling full editing functionality.
3Reliability
If proxy video files are transmitted, then transmission reliability improves, but video quality deteriorates
Solution Approach 1:
Different parts of the video workflow use different quality levels appropriately. Proxy files with lower quality are used for transmission and initial editing operations where full quality is not critical. The original high-resolution files are preserved locally and used for final rendering and delivery, ensuring that each stage of production uses the appropriate quality level.
4Reliability
If physical media or cables are used for video transmission, then transmission reliability improves, but device complexity and operational difficulty increase
Solution Approach 1:
The system replaces mechanical transmission methods (physical media, cables) with wireless electronic transmission of proxy video files. This substitution eliminates the need for physical connection infrastructure while enabling reliable transmission through standardized wireless protocols, reducing operational complexity associated with physical media handling and cable management.

AI summary
The present disclosure relates to a system, method, and apparatus for transmission of proxy video clips for video processing which extracts metadata for an original high resolution video file for transmission together with a lower resolution proxy file to provide seamless remote video editing, even without the original high resolution video. In an embodiment, the present system, method, and apparatus executes a custom metadata extraction process for each video camera model, such that all essential metadata is extracted from the original video footage. The extracted metadata may include information such as frame rate, resolution, color space, codec, etc., and is formatted for transmission together with a lower resolution proxy file to a remote video editing and postproduction location.
