Animated Video Editing With Automatic Character-Text Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video editing processes require manual alignment of characters with line text on a timeline, leading to low efficiency.
Innovation Solution
A video editing method that automatically associates characters with line text using text-to-speech technology, allowing for the generation of animated videos where characters read the corresponding text synchronously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual alignment of characters with line text is used, then precise positioning can be achieved, but video editing efficiency deteriorates
Solution Approach 1:
The system performs automatic character-text alignment using text-to-speech technology and time synchronization, eliminating the need for manual positioning operations. The character automatically associates with the corresponding line text based on temporal relationships, making the system self-sufficient in the alignment task.
Solution Approach 2:
The manual mechanical alignment process is replaced by an automated digital system that uses text-to-speech conversion and time-based synchronization algorithms. This substitution transforms a labor-intensive manual operation into an automated computational process, significantly improving efficiency.
2Productivity
If automatic character-text association is implemented, then editing efficiency improves, but technical complexity increases
Solution Approach 1:
Text-to-speech audio serves as an intermediary element that bridges the character and line text. By converting text to speech and synchronizing it with character actions, the system creates a temporal mediator that automatically establishes the association without requiring complex direct linking mechanisms.
Solution Approach 2:
The system performs preliminary text-to-speech conversion and timing analysis before finalizing the character-text association. This preliminary processing prepares the data in advance, allowing the automatic alignment to occur smoothly during video generation without adding complexity to the final assembly process.

AI summary
This application provides a video editing method performed by a computer device. The video editing method includes: displaying a video editing interface; determining a target character and an input text in the video editing interface; generating an animated video and a line audio, the animated video comprising the target character, and the line audio corresponding to the text for the target character in the animated video; and synchronously playing the line audio corresponding to the text in a process of playing the animated video.
