Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video compression tools require users to have media expertise to set appropriate transcoding parameters, making it difficult for ordinary users to compress media files efficiently and effectively, especially given the variety of AV encoding standards and file formats.
Innovation Solution
A method and system for media file compression that extracts encoding parameters, separates and decodes audio and video streams, computes transcoding parameters, and encodes the streams to create a new media file, ensuring simple and rapid compression without requiring media expertise, using principles such as adjusting frame rates, resolutions, and encoder types to optimize compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic transcoding parameter computation is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system performs self-service by automatically analyzing the source media file's encoding parameters and computing appropriate transcoding parameters without requiring user expertise. The computation module autonomously determines optimal transcoding settings based on the extracted encoding parameters, making the system serve itself rather than requiring external expert intervention.
Solution Approach 2:
The computation module acts as an intermediary between the encoding parameter extraction and the transcoding process. It receives encoding parameters, processes them through computation algorithms, and generates transcoding parameters that bridge the gap between source and target formats, eliminating the need for users to directly handle complex transcoding settings.
2Manufacturing precision
If comprehensive encoding parameter extraction and analysis is performed, then manufacturing precision is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary action by extracting and analyzing encoding parameters before the actual transcoding process begins. This preliminary analysis phase prepares all necessary information about the source file's encoding characteristics, allowing the transcoding to proceed efficiently with pre-determined optimal parameters rather than requiring trial-and-error adjustments during compression.
