Seedance 2.0 just landed in three tools at once — sharper motion, smarter scene understanding, sound generated right alongside the video, and full NSFW support across all three.

What makes it different:

• Understands the whole scene, not just a picture — subject, action, environment, and camera all come together into one coherent clip, with noticeably more stable motion than before

• Two distinct input modes — animate a clip with a first/last frame, or try the new Reference mode: build a full clip from up to 9 image references and 3 audio clips

• Flexible clip length, up to 15 seconds — more room to build out a scene, not just short bursts

• Built-in audio generation — sound and motion land in sync without a separate step

• Precise video editing — in Video-to-Video, swap a costume, background, or lighting while keeping the original movement and timing untouched
