Concept / campaignComplex advertising demo
Use strong image references to hold product shape, color, logo placement, and overall composition while refining local action.


Seedance 2.5 is a professional multimodal video creation model built around long-form narrative, high-capacity reference control, precise editing, and native multilingual generation. Create a single continuous video up to 30 seconds from as many as 50 reference assets.
The official update highlights film and video creation, knowledge content, and complex advertising demos. These concept directions show how the same capabilities can support production work.
Concept / campaignUse strong image references to hold product shape, color, logo placement, and overall composition while refining local action.
Concept / previsUse a full 30-second sequence to direct lighting, camera movement, performance, pacing, and the final emotional beat.
Concept / musicUse background music, human voice, or sound effects as audio-only references to guide rhythm, beat points, and lip sync.
The official Seedance 2.5 update defines the model through longer narrative, stronger references, precise editing, and native multilingual generation.
Generate one continuous video up to 30 seconds, increased from the 15-second single-output limit in Seedance 2.0.
Combine as many as 30 images, 10 video clips, and 10 audio clips in one generation. Referenced audio and video can total up to 30 seconds.
Lock the overall frame and preserve what already works while changing only the selected local detail.
Generate across more than 10 languages without reducing multilingual direction to a post-production step.
Lighting, camera movement, expression, and emotional impact are improved to reduce the artificial AI look and move results closer to live-action production.

Separate the story, reference set, audio direction, and edit priorities so each input has a clear job.
The concrete limits and controls described in the official update summary.
| Dimension | Seedance 2.5 specification | Production value |
|---|---|---|
| Single output | One continuous video up to 30 seconds. | More room for a complete narrative arc and camera progression. |
| Reference capacity | Up to 50 assets: 30 images, 10 videos, and 10 audio clips. | Characters, products, motion, style, and sound can share one brief. |
| Media duration | Referenced audio and video can total up to 30 seconds. | Longer motion and sound context can guide the generated sequence. |
| Precise editing | Lock the overall frame and edit selected local details. | Preserve the successful result instead of rebuilding the full scene. |
| Native languages | Support for more than 10 languages. | Create multilingual content inside the generation workflow. |
| Audio-only reference | Use music, human voice, or sound effects without video. | Direct rhythm, beat points, performance timing, and lip sync. |
Use the prompt to define the 30-second progression, identify what each reference controls, and separate locked composition from local changes.
SUBJECT — A silver-haired rider in a reflective raincoat. REFERENCES — Use @Image1 for identity and wardrobe, @Video1 for the lateral tracking motion, and @Audio1 for rhythm and rain ambience. 00–22 SEC — Begin wide as she crosses a wet boulevard, then move into a medium portrait. Keep the same face, coat, motorcycle, and cool street lighting. 22–30 SEC — Slow orbit as she stops beneath a single white sign. Finish on a stable product-ready frame. EDIT PRIORITY — Lock the overall composition and identity. If adjustment is needed, change only the sign area and preserve everything else.
