Semi-Automatic Video Editing System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual video editing is time-consuming and often results in amateurish outcomes, with unstable videos and imperfect soundtrack synchronization, due to the extensive manual effort required for selecting clips, synchronizing soundtracks, and adding graphical effects.
Innovation Solution
A semi-automatic video editing system for mobile devices that analyzes input videos, suggests additional footage, and processes metadata to automatically select scenes, synchronize soundtracks, and apply graphical assets, reducing user effort while improving video quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual video editing is performed, then user control over video content is high, but editing time and effort are excessive
Solution Approach 1:
The system performs preliminary analysis of the input video to automatically generate scene segments, captions, and metadata before the user begins editing. This pre-processing reduces the time required for manual editing while preserving user control over the final content selection.
Solution Approach 2:
The system introduces an intermediary automated processing layer that acts as a mediator between raw video input and final edited output. This intermediary automatically performs tasks such as scene detection, caption generation, and synchronization, reducing the manual effort required while maintaining user control through selective approval or modification of automated results.
2Adaptability or versatility
If manual video editing is performed, then customization options are high, but video quality and professionalism are insufficient
Solution Approach 1:
The system replaces manual mechanical editing operations with automated computer-based processing. Algorithms automatically perform scene analysis, caption synchronization, and effect application with precision that exceeds manual capabilities, while still allowing users to customize the output through parameter adjustment and selective approval.
3Measurement precision
If extensive manual editing operations are performed, then detailed control is achieved, but synchronization accuracy with soundtrack is imperfect
Solution Approach 1:
The system implements feedback mechanisms that automatically analyze the relationship between video scenes and soundtrack, detecting temporal alignments and generating synchronization recommendations. This feedback loop enables precise synchronization without requiring users to manually adjust timing, as the system continuously monitors and adjusts based on detected patterns.

AI summary
A non-transitory computer readable medium that stores instructions that cause a computerized system to: acquire at least one picture; analyze the at least one picture to provide analysis result; suggest to a user to acquire at least one other picture, if the analysis result indicates that there is a need to acquire at least one other picture; acquire the at least one other picture if instructed by the user; receive from the user metadata related to an acquired picture, the acquired picture is selected out of the at least one picture and the at least one other picture; and process the acquired picture in response to the metadata.
