Create Videos with Synchronized Audio Using Seedance 1.5 Pro
Text-to-Video with Audio Synchronization
Based on your text prompt, the Seedance 1.5 Pro AI model can generate spoken dialogue or voiceover, sound effects, and background music. All audio elements are synchronized with on-screen actions, so speech, motion, and sound stay aligned without additional editing.
Image-to-Video from a Single Image or Start–End Frames

Key Features of the Seedance 1.5 Pro AI Video Generator
Audio-Visual Synchronization with Lip Sync
The Seedance 1.5 Pro AI video model delivers precise audio-visual synchronization, including consistent lip movement when characters speak. Spoken dialogue aligns closely with mouth shapes and facial motion, reducing the mismatch often seen in AI-generated videos and making conversations easier to follow.
Cinematic Camera Control and Multi-Shot Scenes
With Seedance 1.5 Pro, users can describe multiple shots directly in the prompt, including camera angles, transitions, and movement. The model handles shot changes smoothly while maintaining character consistency, enabling more structured, cinematic scenes instead of a single continuous take.
Multilingual and Dialect Support
Seedance 1.5 Pro supports multiple languages, including English, Chinese, Spanish, and Japanese, with particularly strong performance in Chinese dialects. Speech is generated with natural pronunciation and intonation, allowing dialogue to sound fluent rather than robotic.
Emotion-Driven Performance and Scene Dynamics
Seedance 1.5 Pro adjusts voice tone, background music, and sound effects to reflect the intended emotion of a scene. Camera movement and pacing follow the same emotional direction, helping the video convey mood through both audio and visual cues rather than dialogue alone.
Enhanced Physical Realism and Natural Movement
The Seedance 1.5 Pro AI video model applies improved physical simulation to character movement and object interaction. Body proportions remain balanced, motion follows realistic physics, and actions appear smoother and more controlled, reducing unnatural or exaggerated movement in dynamic scenes.
Stable Backgrounds and Scene Consistency
With Seedance AI video model, backgrounds remain visually stable throughout the video. Scene elements stay anchored in place, minimizing flicker, distortion, or unexpected shifts during motion. This helps generated videos look cleaner and more consistent from start to finish.
