Key Features
Discover what makes Seedance 1.5 Pro exceptional
Native Audio-Video Generation in a Single Pass
Powered by a Dual-Branch Diffusion Transformer (DB-DiT) architecture, Seedance 1.5 Pro generates synchronized audio and video simultaneously — not sequentially. This eliminates 'audio drift' and delivers millisecond-precision audio-visual alignment with no post-production needed.
Multilingual Lip-Sync with Emotional Tone
Seedance 1.5 Pro supports multiple languages and dialects with accurate phoneme-to-viseme matching. Characters speak naturally with emotionally aligned lip movements. Whether it's English dialogue or regional accents, the model delivers believable, synchronized speech.
Cinematic Camera Control & Long Takes
Execute professional camera movements including pan, tilt, zoom, dolly zoom (Hitchcock zoom), and tracking shots within a single generation. Create continuous long takes with professional color grading and narrative coherence, all from a text prompt.
10x Faster Inference Speed
Seedance 1.5 Pro delivers up to 10x faster inference compared to previous versions. Generate 720p to 1080p videos in seconds across multiple aspect ratios (16:9, 9:16, 1:1, 4:3, 21:9) with support for text-to-video, image-to-video, and first-last-frame input modes.
