Music-Track Shooting Unit Mapping for Synchronized Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording devices struggle to manage video shooting in synchronization with music tracks, making it difficult to create cohesive video works that align with the rhythm and tempo of the music.
Innovation Solution
An electronic device equipped with a display, input interface, and controller that allows users to set shooting units within a music track, generating management information to associate time ranges with video shooting, facilitating synchronized video capture and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If video recording devices continuously play back video data for each section of music, then video creation over entire music becomes easier, but management of video shooting in synchronization with music track becomes difficult
Solution Approach 1:
The music track is divided into multiple sections, and video shooting is organized into corresponding shooting units that map to these sections. Each shooting unit contains specific shooting information (camera angles, timing, etc.) that corresponds to a particular music section, enabling systematic management of video shooting across the entire track while maintaining synchronization.
Solution Approach 2:
Shooting management information is prepared in advance before actual video recording. This includes pre-defining shooting units, assigning camera angles, setting timing parameters, and organizing the structure of video shooting for each music section. This preliminary organization simplifies the actual shooting process and facilitates easier video creation.
2Measurement precision
If detailed management information is generated for each shooting unit, then synchronization precision with music track improves, but system complexity increases
Solution Approach 1:
The music track structure is copied into a corresponding video structure through shooting management information. Each music section has an associated shooting unit that mirrors its temporal and structural characteristics. This copying approach maintains precise synchronization without requiring complex real-time coordination systems.
Solution Approach 2:
Synchronization is achieved by defining specific parameters for each shooting unit (start time, end time, camera angle, shot type) that directly correspond to music track parameters. By changing and controlling these discrete parameters, precise synchronization is obtained while keeping the management system organized and manageable.

AI summary
An electronic device is provided for managing video shooting in accordance with a music track. The electronic device includes: a display that displays information; an input interface that inputs a user operation; and a controller that generates management information managing a video associated with audio data indicating the music track. The controller causes the display to display a time range within the music track indicated by the audio data and the input interface to receive the user operation setting a shooting unit for the management information, the shooting unit during which a video is shot for the time range within the music track. The controller generates the management information by associating the time range within the music track with the shooting unit set by the user operation.
