Principles of Work
Seedance 1.5 Pro uses a multimodal AI architecture to generate video and synchronized audio from a single image and your text prompts. It analyzes the selected image together with your Narration, Action Prompt, Camera Motion, and Action Template to create a short animated video.
The model animates facial expressions, body movement, and camera motion while generating synchronized speech. It is designed to preserve the appearance of the original subject throughout the generated scene.
Main Features:
High-Quality Lip Sync: Automatically animates mouth movements that perfectly match the generated speech in multiple languages.
Accurate Prompt Interpretation: Excels at rendering subtle human micro-expressions (hesitation, tension, joy). Accurately interprets prompt instructions for hand gestures, facial expressions, and subtle background motion.
Professional Camera Motion: Works well with cinematic camera movements to create polished, presentation-ready videos.
Native Audio Generation: Generates speech and supporting audio elements together with the video for a cohesive result.
Cross-Model Regeneration Ready: Ideal as a baseline for testing how different models render the same prompt settings.
