What is the Seedance 2.5 AI Video Generator?

Seedance 2.5 is ByteDance's next-generation multimodal AI video model, built on the Seedance 2.0 architecture. It generates an entire 30-second video in one coherent diffusion pass and combines up to 50 multimodal reference inputs, so you can control characters, motion, style and composition at the same time. Video and audio are generated together in the same latent space, so sound is natively synchronized without post-processing.

Native 30s 4K, No Stitching

Going beyond the previous 15-second limit, Seedance 2.5 generates a full 30-second video in a single diffusion pass. Get consistent native 4K (10-bit color) results from start to finish, with no need to stitch clips together.

Up to 50 Multimodal Reference Inputs

Use up to 50 reference inputs (previously 12) in a single generation, including images, audio clips, 3D white models and style references. Lock character identity, transfer motion and camera language, and apply a consistent brand style, all at once.

Joint Audio-Video Generation & Precise Prompt Understanding

Audio is processed jointly with video in the same latent space, so sound effects, dialogue and ambience are natively synced to on-screen action. Prompt adherence is improved by about 20%, which means fewer regenerations.

Seedance 2.5 in Action

Explore real examples that show the power of multimodal AI video generation. Each demo shows how images, videos and prompts combine to create stunning results.

Creative Templates & Complex Effects

Precisely replicate fish-eye lens effects, flash overlays and outfit changes. Reference a model's appearance across multiple clothing styles with dynamic camera cuts.

Model reference and outfits

โ€œReference the model's facial features from the first image. The model wears the outfits from reference images 2-6 and approaches the camera with playful, cool, cute, surprised and stylish poses. Each outfit change triggers a camera cut, using the fish-eye lens effect and flash overlay from the reference video.โ€

Motion & Camera Replication

Combine a character's motion from one video with the camera movement from another. Create an epic battle scene with dust effects and cinematic tension under a starry night sky.

Character reference

โ€œReference the character motion from Video 1 and the orbiting camera movement from Video 2. Generate a battle scene between Character 1 and Character 2 under a starry night sky, with white dust rising during the fight. The battle is spectacular and intense.โ€

Native 30s Video Extension

Extend smoothly up to 30 seconds in a single diffusion pass while keeping everything consistent. Create a quirky ad in which a donkey riding a motorcycle moves through a series of cinematic shots.

Donkey riding a motorcycle reference

โ€œReference @image1 and @image2 of a donkey riding a motorcycle and generate a 30-second video. Scene 1: a side shot of the donkey bursting through a fence and startling the chickens. Scene 2: the donkey doing motorcycle stunts on sand, a close-up of the tires, then an aerial shot. Scene 3: the donkey jumps with mountains in the background, and the text 'Inspire Creativity, Enrich Life' is revealed with a masking effect.โ€

Cinematic Audio & Visuals

Create MV-quality content with precise cinematography keywords. Build film-like compositions with golden-hour lighting and a film-grain look.

Cinematic scene reference

โ€œGenerate a 30-second MV. Keywords: stable composition, smooth push-pull, low-angle hero shot, premium documentary feel. Ultra-wide establishing shot, slightly upward-tilted low angle, a cliffside dirt road with a vintage travel car in the lower third, distant sea and horizon for depth, sunset side-back light with volumetric rays through dust particles, cinematic framing, authentic film grain, clothes moving gently in the wind.โ€

Video Editing & Character Replacement

Replace a character while keeping every action and movement from the original video. Swap a female vocalist for a male singer while the band keeps playing.

Male singer reference

โ€œReplace the female lead singer in Video 1 with the male singer from Image 1. His movements must match the original video exactly. No camera cuts. The band keeps playing.โ€

One-Take Long Shot

Create a seamless one-take sequence from multiple reference images. Follow a runner from the street, up the stairs and through a hallway to the rooftop in a single continuous shot.

Scene sequence reference

โ€œ@image1 @image2 @image3 @image4 @image5, one-take tracking shot following a runner from the street up the stairs, through a hallway and onto the rooftop, ending on a view of the city.โ€

3D White Model Previsualization

Block out scene layout, camera framing and motion with 3D white models before the final render. With minimal input, the AI completes an emotional story.

Story inspiration image

โ€œUse the audio from Video 1 to create an emotional video inspired by Images 1-5. Pre-define the camera path with 3D white models, and reference @video1 for the background music.โ€

Create with Seedance 2.5 in 3 Steps

Turn multimodal assets into native 30-second 4K AI video with the most flexible input system available.

1

Upload Reference Assets

Upload up to 50 multimodal reference inputs in a single generation, including images, audio clips, 3D white models and style references. Mix different input types for maximum creative flexibility.

2

Write a Prompt with @ References

Use natural language and @ mentions to specify how each asset is used, for example: 'Reference @Image1 as the character, use @Video1 for camera movement'. Prompt adherence is improved by about 20%.

3

Generate Native 30s 4K Video

Generate native 4K (10-bit) video up to 30 seconds long in a single diffusion pass. Synchronized audio is generated along with the video, ready to share or edit further.

What Creators Say About Seedance 2.5

Hear from filmmakers and content creators who switched to Seedance 2.5.

Getting 30 seconds of 4K in one go is a game changer. I no longer stitch clips together, and everything stays consistent from start to finish.

David Chen, Digital Artist

With 50 reference inputs I can lock the character, style and camera language at the same time. The level of control is on a different level.

Rachel Kim, Content Creator

Because the audio is generated in the same pass as the video, lip sync and sound effect timing are remarkably accurate.

Marcus Thompson, Filmmaker

Prompt adherence is clearly better. I regenerate far less often, so my workflow is much faster.

Sofia Garcia, YouTube Creator
