ByteDance Seed's native audio-video joint generation model. Create cinematic videos with synchronized audio, expressive human motion, and film-grade visuals — from text or image inputs.
Available on SeedDance platform
Seedance 1.5 Pro is a joint audio-video generation model developed by ByteDance's Seed team. Unlike traditional video models that add audio in post-processing, it generates video and audio together — improving sync between motion, dialogue, and ambient sound.
Video and audio are generated together in a single pass — reducing post-processing and misalignment. Voices, footsteps, and ambient sound emerge with the visual scene.
Produces cinematic compositions with controlled camera movements, accurate depth of field, and professional-grade lighting. Close-up shots, wide angles, and dynamic transitions are all supported.
Captures subtle facial expressions, natural body language, and emotionally nuanced movements. Characters maintain pose continuity and identity consistency across the clip.
Interprets complex narrative descriptions including scene layout, performance intent, rhythm, and emotional tone — going beyond simple visual prompts.
Seedance 1.5 Pro focuses on native audio-visual synergy, cinematic camera control, and expressive motion — helping creators move closer to professionally produced results.

Production-oriented features for creators who need synchronized audio-visual clips from text or images.
Write a prompt describing your scene, characters, camera work, and mood — Seedance 1.5 Pro renders it into a cinematic clip with audio.
Bring still images to life. Upload up to two reference images (first and optional last frame) and animate with natural motion, matching audio, and cinematic camera movement.
Audio is generated jointly with video, not added after the fact — so dialogue, music, and ambient sound stay tightly timed with the picture.
Handles complex human performances including dance, gestures, emotional scenes, and multi-person interactions with strong realism and continuity.
Supports expressive camera techniques — panning, zooming, tracking shots, close-ups, and wide establishing shots — with smooth, intentional transitions.
Generate videos at 480p, 720p, or up to 1080p. High-detail textures and cinematic color grading help output ready for professional workflows.
Understands narrative arc, scene transitions, and emotional context. Ideal for short films, brand stories, educational content, and social video production.
Generate clips from 4 to 12 seconds, giving you control over pacing and content length for common short-form use cases.
