Seedance 2.0 is ByteDance’s latest AI video generation model, and it’s a major step up from 1.5. Character consistency, motion quality, lighting, and temporal stability have all been significantly improved. Characters lock their appearance across entire sequences, motion follows realistic physics, and the flickering issues from 1.5 are gone.
The biggest addition is the multimodal input system. You can now feed up to 12 reference files into a single generation — images, videos, audio, and text — and use the tagging system to assign roles to each asset. Combine that with multi-shot storyboarding, and you can generate connected sequences rather than isolated clips.
Seedance 2.0 also generates audio and video simultaneously, so sound effects land in sync with the visuals. Beat matching lets you upload a music track and generate visuals that hit the beats. Lip sync works across 8+ languages including English, Mandarin, Spanish, French, German, Japanese, and Korean. You can generate voiceover with ElevenCreative text-to-speech, feed that in as your audio reference, add a music track for rhythm, and Seedance 2.0 syncs the visuals to match.
It’s not just generation either — you can take an existing video and regenerate specific parts while keeping the rest intact, whether that’s changing elements in a scene or swapping out a character entirely.
