Video Shooting Audio Analysis for Mistake Shot Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video shooting systems lack effective management of mistake shots, particularly in sound collection, leading to inefficiencies and increased production time due to the need for manual checking and potential re-shooting of videos with sound issues.
Innovation Solution
An electronic device and method that utilize audio data analysis to automatically determine mistake shots, specifically those with sound collection problems, and provide alert information to the user, facilitating efficient video shooting and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual checking of sound quality is performed after video shooting, then sound issues can be detected, but production time and labor load increase significantly
Solution Approach 1:
The system performs sound quality determination processing immediately after video shooting by analyzing audio data from the shot video to detect mistake shots. This preliminary detection allows users to identify sound issues before completing the entire shooting workflow, enabling timely re-shooting and eliminating the need for time-consuming manual checking later in post-production.
2Reliability
If comprehensive sound quality checking is performed on all videos, then sound issues are identified, but the complexity of the shooting management system increases
Solution Approach 1:
The system replaces manual sound quality checking with automated determination processing that analyzes audio data using objective criteria. The controller automatically identifies mistake shots by evaluating sound quality parameters, substituting human judgment with algorithmic analysis. This reduces system complexity while maintaining high reliability in sound quality assurance.
3Productivity
If mistake shots are not detected during shooting, then shooting workflow continues smoothly, but re-shooting is required later increasing overall production time
Solution Approach 1:
The system provides immediate feedback by displaying alert information when mistake shots are detected during or after video shooting. This real-time feedback mechanism allows users to identify and address sound quality issues promptly, preventing the accumulation of undetected mistake shots that would require time-consuming re-shooting later. The feedback loop closes the gap between shooting and quality verification.

AI summary
An electronic device manages video shooting. The electronic device includes: a display that displays information; an input interface that inputs a user operation; and a controller that controls the display according to the user operation input in the input interface. The controller receives an instruction to shoot a video in the input interface, and acquires a result of determination processing to determine whether or not the video is a mistake shot, based on audio data in the shot video. When the acquired result of the determination processing is the mistake shot, the controller displays alert information indicating the mistake shot of the video on the display.
