Why creators choose Seedance 2.5
Create a beginning, middle, and end
Thirty seconds means you can craft a narrative that actually tells a story. Your character holds across the scene, the light holds, and nothing drifts at the seams.
Your own material does the directing
With 30 images, 10 clips, and 10 audio files in one generation, label each in the prompt and the model reads it as a brief: this face, that palette, this camera move, that voice.
Sound that lands finished
Dialogue, music, and effects are written alongside the picture rather than laid over it afterwards. Footsteps hit on the footstep — that takes a whole pass out of your edit.
Fewer takes before the keeper
Seedance 2.5 follows prompts roughly 20% more accurately than Seedance 2.0. If 2.0 typically takes three or four attempts to nail a specific camera move, 2.5 often gets there sooner.
Define aspect ratio
Set it yourself or let the model decide from your prompt: 16:9, 9:16, 1:1, or 21:9. Useful when you're not yet sure where the clip will run.
Four steps from an empty prompt to a finished clip with sound using Seedance 2.5 on this platform.

Start creating with Seedance 2.5
Generate 30-second clips from up to 50 references on this platform. One workflow, commercial-ready output, and every control you need to direct the scene.
Beyond duration and references, Seedance 2.5 handles multi-shot sequences, targeted edits within a defined time range, and clip extension — all within one generation.
What Seedance 2.5 can do
Multi-shot generation
Describe several shots in one prompt, and the model cuts between them, holding style and continuity across each change.
Reference-driven editing
Replace a subject, add or remove an element, or redraw a region. Limit the change to a time window — for example 0:02 to 0:05 — and the rest of the clip stays untouched.
Extension in both directions
Continue a clip from its final frame, or generate the moment before it using the first frame as the endpoint. Style, rhythm, and camera logic carry across.
Seamless bridge
Hand the model two clips, and it generates the transition between them, matching the motion on both sides.
First and last frame
Set the opening and closing image so the model builds the movement in between. Match the aspect ratios of both, or the last frame is cropped to fit the first.
Smart Duration
Set any length from 4 to 30 seconds, or hand the decision over — the model picks a natural cut point in the 4 to 15 second range.
Audio-only references
Feed an audio file on its own to drive dialogue, music, or effects. No matching image or video reference is required.
Dialogue in eleven languages
Generate dialogue in English, Chinese, Spanish, Portuguese, Japanese, Korean, Arabic, Vietnamese, Thai, Indonesian, or Malay.
Seedance 2.5 extends clip length and reference depth. Seedance 2.0 remains the choice for maximum resolution workflows up to 4K.
