Video Synthesis Beat Synchronization via Dotting Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating videos by combining material images and music lack synchronization, resulting in videos that do not effectively integrate music and images, failing to meet user needs for engaging content.
Innovation Solution
A method and apparatus for synthesizing videos by acquiring audio data with beat time points, acquiring material images, and synchronizing these images with the audio data based on the beat time points to create a synthesized video where image switches occur at audio beat times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If background music is added to videos in the related art, then the video has audio accompaniment, but the background music and material images are not synchronized, resulting in poor integration effect
Solution Approach 1:
The patent extracts beat information from audio data in advance and stores it as dotting data including beat time points and beat values. This preliminary processing of audio rhythm information enables subsequent synchronization with video frames without adding complexity during the actual video synthesis process.
Solution Approach 2:
The patent introduces dotting data as an intermediary element that bridges audio data and video frames. The dotting data contains beat time points and beat values that serve as a reference standard, allowing the system to determine which video frame corresponds to which musical beat, thereby achieving synchronization.
2Adaptability or versatility
If video synthesis is performed without beat synchronization, then the process is simple, but the integration effect between music and images is poor and does not meet user needs
Solution Approach 1:
The system performs preliminary extraction of beat information from audio data and stores it as dotting data before video synthesis. This advance preparation of rhythm reference information enables sophisticated beat-synchronized video creation without complicating the actual synthesis workflow for users.
Solution Approach 2:
The system automatically extracts beat information from audio data and performs synchronization without requiring manual user intervention. The dotting data structure enables the system to self-determine optimal frame switching points based on musical beats, providing high-quality synchronized video output automatically.
Data Source
AI summary
A method for synthesizing a video includes: acquiring audio data and dotting data corresponding to the audio data, the dotting data including a beat time point and a beat value corresponding to the beat time point of the audio data; acquiring a plurality of material images from a local source; and synthesizing, based on the dotting data, the plurality of material images and the audio data to acquire a synthesized video, a switching time point of each of the material images in the synthesized video being the beat time point of the audio data.
