Music Point Analysis for Video Clip Timeline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in marking music points in audio materials as they often cannot hear these points, and even if they can, it is time-consuming to locate them manually for video clipping purposes.
Innovation Solution
A method and apparatus that analyze initial music points, such as beat and note starting points, to display identifiers on a clip timeline, allowing users to select and align music points automatically, thereby facilitating video clipping by generating corresponding video clips based on these points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users manually mark music points in audio materials, then they can identify music points, but it takes a lot of time and users often cannot hear the music points
Solution Approach 1:
The system performs automatic music point analysis on the audio material without requiring user listening or manual marking. The analysis unit automatically identifies beat points, note starting points, and other music points through audio signal processing, making the system serve itself rather than relying on user input
Solution Approach 2:
The patent replaces the manual mechanical process of listening and marking music points with an automated audio analysis system that uses signal processing algorithms to detect and identify music points programmatically
2Ease of operation
If users manually locate music points by listening, then they can identify music points, but it is time-consuming
Solution Approach 1:
The system performs preliminary automatic analysis of the audio material to pre-identify all music points before the user needs them. The analysis unit processes the audio in advance, generating a list of music points with their positions, so when users need to create video clips, the music points are already prepared and ready for selection
Solution Approach 2:
The system automatically performs the time-consuming task of music point detection without requiring user intervention, making the system self-sufficient in identifying music points while users only need to review and select from the pre-identified points
3Ease of operation
If automatic music point analysis is implemented, then user effort is reduced, but system complexity increases
Solution Approach 1:
The system divides the complex audio analysis task into separate functional modules: an analysis unit that detects music points, a display unit that presents them to users, and a video clipping unit that uses them. This segmentation allows each module to handle a specific aspect of the problem, reducing overall system complexity through modular design
Solution Approach 2:
The patent introduces a display unit as an intermediary between the automatic analysis unit and the user. This intermediary presents the automatically identified music points in a user-friendly format on the operation interface, allowing users to review and select points without directly interacting with the complex analysis processes

AI summary
Disclosed are a method and apparatus for displaying music points, and an electronic device and a medium. One specific embodiment of the method includes: acquiring audio material; analyzing initial music points in the audio material, wherein the initial music points include beat points and/or note starting points in the audio material; and on an operation interface of video clipping, displaying, according to the position of the audio material on a clip timeline and the positions of target music points in the audio material, identifiers of the target music points on the clip timeline, wherein the target music points are some of or all of the initial music points. According to the embodiment, the time for a user to process audio material and to make music points is reduced, and the flexibility of tools is also guaranteed.
