Ultra-realistic. ARRI Alexa Mini, 50mm lens. Hard natural light, shallow depth of field. Steadicam medium shot tracks a sharp young man in a black suit walking through a busy street. He snaps his fingers: a sharp white shockwave ripples out, freezing dust, pigeons mid-flight, and pedestrians in place. Silence falls; only his footsteps echo. He brushes frozen pigeons, eyes a statuesque woman in a red dress with wind-swept hair, and whispers, "Perfect." He snaps again—a stronger reverse shockwave. Time resumes: crowds move, pigeons scatter, leaves fall. He melts into the city as the camera cranes up. Fade to black.

Create Better Videos With Seedance 2.5 AI Video Generator
Seedance 2.5 is ByteDance's advanced AI video model for longer, more controlled creation. If 5–15 second clips feel too short, complex motion is hard to guide, or your results lose consistency across scenes, Seedance 2.5 gives you more room to create. With longer video generation, multimodal references, precise motion control, and flexible editing, you can build ads, product videos, social clips, and cinematic scenes with fewer retries and more consistent results.
Create Up to 30s Videos With Better Continuity
Still cutting several short clips together just to finish one scene? Seedance 2.5 can generate continuous videos up to 30 seconds, giving actions, camera moves, dialogue, and story beats more room to unfold naturally. Longer generation also helps characters, lighting, backgrounds, and motion stay consistent from start to finish. In AI Ease, you can keep a longer idea in one generation instead of breaking it into multiple short clips.
Combine Up to 50 Multimodal References
Some ideas are simply too detailed for one prompt or one reference file. Seedance 2.5 can work with up to 50 multimodal references in one generation, including 30 images, 10 videos, and 10 audio files. Bring character photos, product shots, motion clips, music, voice, and other references into AI Ease to shape different parts of the same video. With more source material to work from, the model can better follow your characters, style, movement, sound, and overall creative direction.
Control Different Parts of Your Video With R2V
Getting the exact result from text alone can be difficult, especially when motion, timing, and character consistency all matter. With R2V (Reference-to-Video) control, different references can guide different parts of the generation. Use images to define characters, products, outfits, or visual style; videos to guide body movement, action timing, interactions, and camera paths; and audio to shape voice, sound, rhythm, or pacing. Add your references in AI Ease and tell Seedance 2.5 how each one should be used, giving complex scenes clearer creative direction from the start.
Edit Specific Details and Create in 4K
Found one detail you want to change after generation? You do not need to rebuild the whole video. Seedance 2.5 supports localized video editing, so you can adjust specific characters, objects, or visual details while keeping the rest of the scene, motion, and composition intact. It also supports 4K video output for sharper textures, clearer subjects, and cleaner details. In AI Ease, you can keep the parts that already look right and focus your edits only where they are needed.
What Can You Create With Seedance 2.5?
Product Ads
Turn product photos into polished AI product videos with close-ups, camera movement, and product interaction. A faster way for ecommerce sellers and brands to create launch ads, landing page visuals, and social content without a full shoot.
Social Videos
Create longer TikTok, Reels, and Shorts with up to 30 seconds in one generation. Add more actions, transitions, and story beats without splitting one idea into several short clips on AI Ease.

How should I write a prompt for Seedance 2.5?
Keep your prompt clear and specific. Describe the subject, action, camera movement, setting, lighting, and mood, then use references for details that are easier to show than explain. For example: "A woman walks through a rainy Tokyo street at night, slow tracking shot, reflections on the pavement, soft neon light, cinematic mood." If you use images, videos, or audio in AI Ease, tell Seedance 2.5 what each reference should control.
What is the difference between Seedance 2.0 and Seedance 2.5?
Seedance 2.0 is better suited to shorter AI video generation, with clips up to 15 seconds and more limited reference input. Seedance 2.5 pushes this much further with up to 30-second videos, 4K output, up to 50 multimodal references, R2V (Reference-to-Video) control, and localized video editing. In practice, Seedance 2.5 is a better fit for longer scenes, more complex motion, and projects that need tighter control over characters, style, sound, and continuity.
