Seedance 2.0 makes video with sound, in clips of up to 15 seconds that can cut between shots. Pick it from the model menu in DreamBench’s composer: DreamBench plans your video, Seedance 2.0 makes every scene, and you can redo any scene on its own.

**What Seedance 2.0 is.** ByteDance’s Seed team launched Seedance 2.0 in February 2026 as a model that generates picture and sound together. A single clip runs from 4 to 15 seconds and can hold several shots, so a scene can open wide and cut to a close-up in one generation. ByteDance built it around direction: it follows detailed prompts closely, can carry a character’s look, a setting or a prop over from reference images, and keeps a subject consistent as the action unfolds. Its sound is stereo, with music, ambience and voices generated in time with the picture. ByteDance is open about its limits: fine detail can waver, full photorealism and lively motion still need work, consistency across several subjects and text in the picture can slip, and the sound occasionally distorts. In July 2026 ByteDance released Seedance 2.5, which stretches a single generation to 30 seconds.

**What Seedance 2.0 is good at.**
- Up to 15 seconds, several shots: One generation can hold a short sequence, say an establishing view, a two-shot and a reaction, and the model works out the camera moves from your description.
- Stereo sound with the picture: Music, ambience, voices and small sounds like rustling fabric are created together with the images, in stereo, and timed to what happens on screen.
- Complex movement: ByteDance says it handles scenes where people move fast and interact, like pair figure skating or a sports match with several players, keeping the motion stable and physically plausible.
- Direction from reference images: A reference image can set a character’s look, a location or a prop, and Seedance 2.0 carries it into the video while keeping the subject consistent.

**Seedance 2.0 on DreamBench.**
- At 720p, DreamBench renders with Seedance 2.0 Fast, the variant ByteDance designed for speed. At 1080p and 4K it uses the full Seedance 2.0 model. 4K comes in widescreen (16:9) or portrait (9:16), on Plus, Ultra and Studio.
- Sound is your choice, and a second of Seedance 2.0 costs the same with it on or off, as the rates above show.
- Seedance rejects any reference image with a real person’s face in it, so describe people in your prompt or let DreamBench design the characters. If a video needs a reference like that, choose another model for it.
- Through ByteDance’s own tools, Seedance 2.0 can also edit and extend existing clips and use video or audio clips as references. On DreamBench, each scene is made from your prompt and your reference images, and to change one you give that scene new direction and regenerate it.

**Prompt ideas.**
- The last octopus: Early morning at a busy fish market. A young cook points at the last octopus on the ice and asks the old fishmonger, “Is that one still fresh?” He grins: “Caught it before you woke up.” Close-up on the scale as he weighs it, then a wide shot as they shake hands across the counter. Gulls overhead, ice being shoveled, the crowd’s chatter.
- One run through the bowl: A skateboarder drops into an empty concrete bowl at golden hour. The camera follows low behind her as she carves the wall, pops out over the lip, grabs the board in mid-air and lands clean. Cut to her friend on the deck, whooping and filming on his phone. Wheels roaring on concrete, the clack of the tail, distant traffic.
- Lantern boats at dusk: Hand-painted watercolor animation, 3 shots in 15 seconds. At dusk, a girl and her grandfather set a paper lantern boat on a village river. First, their hands lower it onto the water. Then the boat drifts past reeds and fireflies as the light fades. Last, they sit side by side on the bank, her head on his shoulder. A soft bamboo flute, crickets, lapping water.

- **Does Seedance 2.0 accept photos of real people as references?** No. Seedance 2.0 rejects reference images that show a real person’s face because ByteDance’s API does not accept them.

- **How much does Seedance 2.0 cost on DreamBench?** Credits are charged per second of video, with a base amount per video, and the per-second rate drops when sound is off. The table on this page lists the current rates, and the composer shows the exact cost before you generate.

Both make sound with the picture and can cut between shots within a clip. On DreamBench, Seedance 2.0 renders 4K on Plus and above.
- **Is Seedance 2.0 open source?** No. ByteDance offers Seedance 2.0 through its own platform and API and has not published the model’s weights; its Hugging Face organization lists no Seedance model. You need no GPU or setup to use it: on DreamBench you pick it from the composer’s model menu.
- **Can Seedance 2.0 make a video from a photo on DreamBench?** Yes, from reference images of a character, prop or place, up to 8 per video, as long as none shows a real person’s face. ByteDance’s own tools also accept video and audio clips as references; on DreamBench each scene is made from your prompt and reference images.
- **What makes a good Seedance 2.0 prompt?** Give it a subject, one action, the setting, one camera move, the light and a style word, then the sound. For a clip with several shots, write the shots in order. Put spoken lines in quotation marks and say what else should be heard, because Seedance 2.0 generates the soundtrack from the prompt.
- **What are Seedance 2.0’s limits?** ByteDance says fine detail can waver, text in the picture and consistency across several subjects can slip, and the sound occasionally distorts.
