Who makes Seedance 2.0?

ByteDance's Seed team. It was announced in February 2026 as the successor to Seedance 1.5.

Does the video come with sound?

Yes. Sound is generated together with the picture, including music, ambience, effects and dialogue, in stereo.

How long can a clip be?

4 to 15 seconds per generation. For up to 30 seconds in one pass, use Seedance 2.5.

Can I use video and audio as references, not only images?

Yes. A video can carry camera movement or choreography, and an audio clip can set rhythm or a voice. State in the prompt what each one should contribute.

What is Seedance 2.0?

Seedance 2.0 is ByteDance Seed's audio-video model. It reads text, images, video and audio in one brief and returns up to 15 seconds of multi-shot video with sound generated alongside the picture, so one run can come back as a cut sequence rather than a single take.

What you can make with the Seedance 2.0 tool

These are the jobs people actually bring to Seedance 2.0, and the settings each one needs.

Performance and sport

Scenes with several people moving at once, like a pair skating routine or a dance, where timing and contact have to look physically right.

Storyboard to film

Hand it a storyboard, a character, a location and props as separate images, and ask for the short film they describe.

Ads with sound

Product spots and explainers where the music, ambience and voice need to land on the same beat as the picture.

What Seedance 2.0 does well

Each clip below is one of ByteDance Seed's published Seedance 2.0 examples, cut to ten seconds. They show the four things the model was built to improve over earlier versions.

Official example · ByteDance Seed

Motion that obeys physics

Multi-person interaction and fast, complex movement stay stable: in the skating example, lifts, spins and landings hold together across the whole routine.

Official example · ByteDance Seed

References with a job each

Name what each upload is for, such as the script, the character, the scene or the props, and the model borrows exactly that from it.

Official example · ByteDance Seed

Follows detailed instructions

Long prompts with several characters and a sequence of actions come back in order, with each person staying recognizable.

Official example · ByteDance Seed

Sound made with the scene

Music, ambience, effects and voices are generated as separate stereo layers timed to the picture, down to small sounds like rain on a blade.

Compared with Seedance 2.5

Shorter clips (up to 15 s) but a higher resolution ceiling, up to 4K

Best decision signal

A short, finished shot with sound, possibly delivered in 4K

How to direct Seedance 2.0

Upload references by role

Add the images, clips and audio the shot should draw on. Up to 9 images, 3 videos and 3 audio clips can go into one run.

Say what each one is for

Refer to uploads by number in the prompt: the character from Image 1, the camera move from Video 1, the rhythm from Audio 1. Then describe the action and sound you want.

Pick length and resolution

Draft at 480P or 720P, then rerun the version you like at 1080P or 4K. The finished video appears in Studio.
