Seedance 2.0
ByteDance Seed Team (Beijing, China / Singapore HQ) — Unified audio-video generation in a single pass. 4 to 15 seconds with synchronized music, dialogue, and sound effects. Multiple shots in one output.
Strengths
Native audio-video generation
Music, dialogue with precise lip-sync, and sound effects are all produced in the same generation pass as the video — no need to layer audio in post.
Multi-shot in one clip
Within 15 seconds, Seedance 2.0 produces multiple shots with natural cuts and transitions — it feels like an edited sequence rather than a single continuous clip.
Exceptional motion stability
Characters, objects, and camera stay consistent across the full generation. Movement is natural and physically plausible.
6 aspect ratios
From 16:9 for YouTube to 9:16 for reels to 21:9 for cinematic compositions — every standard ratio is supported.
