Multi-Scene Video Recording Description File for Unified Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in editing video files recorded by multiple cameras on intelligent terminals after multi-scene video recording is completed.
Innovation Solution
A method and apparatus for multi-scene video recording that generates a description file during the recording process, allowing video files from multiple cameras to be separately stored and simultaneously played, edited, or shared on a single interface based on the description file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cameras record videos separately, then video recording capability is improved, but video file processing complexity increases
Solution Approach 1:
The patent introduces a description file as an intermediary data structure that mediates between multiple separately recorded video files. This description file contains metadata about each video file including file paths, timestamps, and camera parameters, allowing the system to manage multiple video files through a unified interface without increasing processing complexity. The description file acts as a central index that simplifies access and manipulation of multiple video files.
Solution Approach 2:
The patent creates a universal processing interface that can handle multiple video files from different cameras simultaneously. The same interface used for single-camera video processing is extended to support multi-camera recordings through the description file, allowing play, edit, and share operations to work uniformly across all recorded videos without requiring separate processing logic for each camera.
2Ease of manufacture
If video files from multiple cameras are separately stored, then storage organization is improved, but user operation convenience deteriorates
Solution Approach 1:
The system performs preliminary organization of video files by creating the description file during the recording process itself. This description file pre-organizes all video file information including paths, timestamps, and camera identifiers, so that when users need to access or process the videos, the work of organization has already been completed. This eliminates the need for users to manually manage multiple video files after recording.
Solution Approach 2:
The description file serves as an intermediary layer between the separately stored video files and the user interface. Instead of requiring users to directly manage multiple video files, the system provides a unified interface that operates on the description file, which in turn manages all video files. This intermediary approach maintains storage organization while significantly improving user operation convenience.
3Productivity
If a description file is generated to manage multiple video files, then video processing efficiency is improved, but data management complexity increases
Solution Approach 1:
The patent segments the data management system into two distinct components: the description file containing metadata and references, and the actual video files containing media data. This segmentation allows the system to process video files efficiently by working with the lightweight description file for coordination, while keeping the heavy video data separate. The description file is divided into structured fields (file paths, timestamps, camera parameters) that can be easily parsed and managed.

AI summary
This application provides a multi-scene video recording method and apparatus, and an electronic device. In the method, a description file may be generated in a multi-scene video recording process, and video files recorded by cameras may be separately stored. Further, the video files recorded by the cameras may be simultaneously played, edited, or shared on a same interface based on the description file, so that a user can perform, based on a requirement of the user, an operation on the video files generated by the multi-scene video recording, thereby improving convenience of video file processing.
