BoomCut uses patented technology to solve the problem:
- Lip-sync drive technology: When this option is checked, the AI will analyze the voice characteristics of the dubbed voice and automatically adjust the character's mouth movements
- frame-level alignment: The system calibrates the audio and video tracks in 0.04 second increments to ensure subtle expression synchronization.
- Preview of the adjustment mechanism: Provide frame-by-frame checking function after translation is completed, and fine-tune keyframe position manually.
- Intelligent buffer design: automatically inserts reasonable frame intervals for fast-talking languages to avoid lagging.
Tests have shown that the solution can achieve professional dubbing-level synchronization for translated videos above 95%.
