Seedance 2.5 AI Video Features

30-Second Native Video Generation

Seedance 2.5 raises the native generation length from 15 seconds to 30 seconds. This gives creators more room for dialogue, camera movement, action buildup, and short narrative scenes without relying on multiple stitched clips.
PromptGenerated Clip
A cinematic 30-second 3D steampunk motion sequence with smooth seamless camera movement: [0–10s] an antique brass clock face unfolds into rotating gears and fog, as the camera dives through to reveal an ornithopter rising from aged-book canyons; [10–20s] the camera follows it into a spinning brass zoetrope with galloping mechanical horse projections, then transforms into a floating brass cable car moving through a glowing gear forest; [20–30s] the camera tilts down to a wind-up wooden sailboat cutting through deep-blue glass waves, which turn into a giant moon, ending with lantern-carrying explorers on a crystal ridge as the camera spirals back to the ticking brass clock.

Up to 50 Full-Modal References

The model can use up to 50 full-modal reference materials, including character close-ups, product photos, scene references, motion videos, audio cues, and text prompts. This helps improve consistency across people, objects, settings, style, rhythm, and camera direction.

Bright and colorful commercial ad style, featuring fruit cookies in four flavors: strawberry, apple, grape, and orange. Use @Image 1 as the strawberry flavor reference. Arrange the cookies and matching fruits in clean, premium geometric arrays with strong rhythm and order. Open with fast fruit-focused shots inspired by @Video 1, then cut to neatly arranged cookies and close-ups with motion like @Video 2. In the climax, a cookie snaps in slow motion, with fruit filling bursting, crumbs flying, and juicy texture emphasized, referencing @Video 3. Show a horizontal product array with rhythmic motion inspired by @Video 4, then return to fast-paced editing. End with the text “One bite of crispness, a heart full of delight” appearing in quick word-by-word motion, followed by a product freeze-frame and cookies and fruits spreading outward like @Video 6, creating a young, energetic, delicious, shareable brand-ad atmosphere.

More Controllable Video Editing

Seedance 2.5 is designed for finer video edits. It can preserve identity, action, pacing, camera composition, and shot structure while replacing selected environments, outfits, props, visual effects, or subject details.
PromptReference ImageGenerated Clip
Keep the character, jungle environment, camera movement, composition, action rhythm, and duration unchanged from @Video 1. A blue-white energy bow and a glowing arrow, as referenced in @Image 1, gradually appear in the character’s hands. The bow should slowly take shape through the subtle aggregation of electric arcs and particles, with delicate flowing current textures, slight volumetric light, and a stable energy outline. As the character draws the bow, a bright energy arrow forms at the center of the bowstring. The moment the character releases, the arrow shoots out at high speed, leaving behind a bright, thin, continuous, and sharply defined energy trail.

A More Director-Like AI Workflow

Instead of generating isolated short clips, Seedance 2.5 moves closer to a director workflow: provide references, guide the scene, maintain continuity, and revise specific visual details without rebuilding the entire video from scratch.

Single continuous take, smooth camera following a person in a black coat from **@Image 1** walking left to right through six connected rooms. Each room keeps the same structure as **@Image 2**: white walls, light herringbone wood floor, French floor-to-ceiling double windows, and white sheer curtains, but each has a completely different outside view and mood. 0–5s: comic-book fight room, the character battles and defeats the figure from **@Image 3**. 5–10s: warm felt-style room with a sunflower field outside **@Image 4**, soft orange light, and a painter painting sunflowers **@Image 5**; the main character also turns into felt style. 10–15s: sad black-and-white manga stop-motion room, rainy outside, a lonely person sits on the floor with an unanswered phone call; the main character switches the light off and on, turning the room colorful as flowers bloom everywhere. 15–20s: joyful underwater room inspired by **@Image 6**, the character swims through coral reefs and fish. 20–25s: surprise room with fireworks outside **@Image 7**, colorful flashing reflections and a cheering atmosphere. 25–30s: the character enters a blank room, snaps their fingers, snap sound effect, cut to black, and the word “seedance” appears in the center, referencing **@Image 8**. Cinematic, high-end fashion commercial style, emotional lighting driven by each window view, no text except the final title.

3D White-Model Previsualization

The 3D white-model workflow lets users provide a simple scene layout and reference style, then generate a more detailed rendered video. This is useful for planning camera movement, blocking, space, and visual atmosphere before final production.

Multilingual Creative Support

Seedance 2.5 also emphasizes broader language support, making it more useful for overseas marketing, multilingual short videos, localized social campaigns, and global creative teams.
