Inside the Seedance 1.5 Pro API
Every Seedance 1.5 Pro API request can carry synchronized native audio, directed camera motion, consistent characters, and lip sync that tracks multiple languages.
Native Audio Generation
The Seedance 1.5 Pro API generates dialogue, sound effects, and ambient audio in the same pass as the video. Sound and motion stay locked together, so clips arrive ready without a separate dubbing step.
Cinematic Camera Control
Describe a pan, orbit, dolly, or zoom in plain language and the Seedance 1.5 Pro API executes the move on screen. This gives creators shot-level direction without manual keyframing or editing tools.
Multilingual Lip-Sync
Need dialogue that matches the mouth in more than one language? The Seedance 1.5 Pro API aligns speech with lip movement across languages, so localized ads and multilingual dialogue scenes look natural.
Multi-Shot Character Consistency
If a story spans several clips, the Seedance 1.5 Pro API holds faces, clothing, and style steady across every shot. That consistency makes it dependable for episodic ads, product series, and character-driven narratives.
