Seedance 2.5 AI Video Generator
Seedance 2.5 generates up to 30 seconds of video in one pass and supports up to 50 multimodal references, with stronger prompt adherence, professional video editing and extension capabilities, and native support for 10+ languages. It is built for longer narratives, reference-driven workflows, and precise creative control.
Key Features of the Seedance 2.5 AI Video Generator
Longer video generation, richer multimodal references, and more precise creative control make complex AI video production more consistent and efficient.
Native 30-Second Video Generation
Generate continuous videos up to 30 seconds in a single pass while maintaining character, motion, and scene consistency, giving complete narratives, product showcases, and ads more room to develop.
Up to 50 Multimodal References
Use up to 30 images, 10 video clips, and 10 audio clips to control consistency across characters, products, scenes, camera work, visual style, and sound.
Advanced Reference-to-Video Control
Seedance 2.5 understands motion, camera movement, pacing, and spatial relationships in reference videos, then applies them to new scenes for more precise reference-to-video (R2V) generation.
Timestamp-Level and Multilingual Control
Define actions, shots, and scene changes by time range, and write prompts in multiple languages for more precise control over pacing and narrative structure.
More Precise Video Editing
Edit characters, products, backgrounds, lighting, or specific regions without regenerating the full video, while preserving the original motion, composition, and visual continuity whenever possible.

Generate Coherent 30-Second Videos in One Pass
Seedance 2.5 increases the maximum duration per generation from 15 to 30 seconds, producing longer, more coherent videos without stitching multiple clips together. It is better suited to complete narratives, complex camera work, and extended scenes.
Example prompt
Create a 30-second cinematic 3D steampunk animation featuring a vintage miniature world and continuous, fluid fly-through camera movement. 0–10 seconds: Begin on a brass clock face that unfolds into spinning gears. The camera flies through the gears as a mechanical ornithopter rises from a canyon of antique books. 10–20 seconds: Follow the ornithopter into a brass zoetrope, where the light and shadow of a mechanical horse transform into a suspended cable car traveling through a forest of gears. 20–30 seconds: Tilt down to a clockwork sailing ship crossing deep-blue glass waves. The sea transforms into a giant glowing moon as a lantern-carrying explorer walks along a crystal ridge. Spiral outward back to the brass clock face, then show the logo from @Image 1 in the final second. Maintain photorealistic brass machinery, cinematic lighting, shallow depth of field, and seamless transitions throughout, creating an epic fantasy-adventure atmosphere.

Use Up to 50 Multimodal Reference Inputs
Seedance 2.5 accepts up to 50 reference assets in a single generation—30 images, 10 video clips, and 10 audio clips. Mix modalities freely for greater creative control, or generate video from an audio reference alone without adding an image or video.
Example prompt
Create a bright, colorful commercial centered on fruit-flavored sandwich cookies in strawberry, apple, grape, and orange. Use @Image 1 as the reference for the strawberry flavor. Arrange the cookies and matching fruit in precise geometric patterns for a clean, premium look with strong visual rhythm. Open with fast-moving fruit to establish the focal point, using @Video 1 for composition and cutting on the musical downbeat. Then show neatly arranged cookies and close-up product shots, using @Video 2 as the reference for motion and camera movement. At the climax, break one cookie in half and shift into slow motion as the fruit filling bursts out and crumbs scatter, emphasizing juicy texture and impact, based on @Video 3. Next, expand the cookies into a horizontal array with rhythmic arcing motion inspired by @Video 4, highlighting visual order and product variety, then return quickly to fast-paced editing. For the ending, bring in the English line "One bite of crispness, a heart full of delight" word by word in rapid succession, with bold rhythmic text animation and a final product lockup, based on @Video 5. Close with a branded composition as the cookies and fruit radiate outward, inspired by @Video 6. The overall mood should feel youthful, energetic, delicious, and shareable.

Seamless Video Extension
Seedance 2.5 can extend an existing video across multiple rounds while automatically preserving its aspect ratio. It maintains continuity in characters, lighting, color, and motion so new footage blends naturally with the source, turning short clips into more complete scenes.
Example prompt
Extend @Video 1: after the window opens, let the camera move naturally into the gallery interior and transition into @Video 2. Then continue forward into the painting and blend seamlessly into @Video 3.

More Precise AI Video Editing
Seedance 2.5 supports precise targeted edits to existing video, allowing you to modify or replace selected people, clothing, props, and scene elements without regenerating the entire clip. It preserves the original composition, lighting, and temporal continuity whenever possible for faster, more controlled revisions.
Example prompt
Video edit: remove everyone except the main subject. Keep the main subject, background, camera movement, and lighting unchanged.
