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, Seedance 1.5 Pro generates video and audio simultaneously — delivering perfect synchronization between motion, dialogue, and ambient sound.
Video and audio are generated together in a single pass — no post-processing, no misalignment. Voices, footsteps, and ambient sound emerge naturally from 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 entire clip.
Accurately interprets complex narrative descriptions including scene layout, performance intent, rhythm, and emotional tone — going far beyond simple visual prompts.
Seedance 1.5 Pro sets a new benchmark in AI video generation with capabilities that bridge the gap between AI-generated and professionally produced content.

A comprehensive set of production-grade features designed for creators who demand the best from AI video generation.
Write a prompt describing your scene, characters, camera work, and mood — Seedance 1.5 Pro renders it into a polished cinematic clip with audio.
Bring your still images to life. Upload a reference image and let Seedance 1.5 Pro animate it with natural motion, matching audio, and cinematic camera movement.
