What Is Seedance 2.5 and What Can It Do

By the Krea Team. Published July 9, 2026. Updated October 26, 2026.

Seedance 2.5 is ByteDance’s latest AI video generation model, and it’s available on Krea now. It generates complete clips of up to 30 seconds at up to 1080p from a single prompt, accepts up to 50 multimodal references (30 images, 10 videos, 10 audio files), and follows complex prompts more reliably than Seedance 2.0.

Seedance 2.5 is available on Krea’s Pro plan and above, in the Krea Video tool and through the API.

How Seedance 2.5 improves on Seedance 2.0

Seedance 2.5 is a major step up from 2.0. Here’s what changes:

• Clip length doubles to 30 seconds. A full 30-second clip generates in one pass. Characters, lighting, and scene continuity stay locked from first frame to last. No stitching, no separate passes. Any whole-second duration from 4 to 30 seconds is supported.

• 480p, 720p, or 1080p output. Pick 480p or 720p while iterating and 1080p for the final take. For 4K delivery, upscale the result with Krea’s video enhancer.

• 50 multimodal reference inputs. Up from 12 in Seedance 2.0. Supply a reference for every character, product, or object in your scene using images, video clips, and audio files. Each subject stays stable across the full clip.

• Video editing, extension, and reframing. Give Seedance 2.5 an existing clip as a reference and describe the change, extend a clip past its last frame, or reframe it to a new aspect ratio, without rebuilding the shot from scratch.

• Better prompt adherence. Complex briefs with specific camera angles, character actions, and lighting directions resolve correctly more often on the first generation.

• Native audio sync. Audio is generated in the same pass as the video. Footsteps, ambient sounds, and effects are synchronized to on-screen action without a separate audio step.

Seedance 2.5 example prompts and results

Every video below was generated by Seedance 2.5 with the exact prompt shown. Each clip is a single generation with native audio.

Backward Glance in Golden Light

A young woman with windswept dark hair and an oversized brown hoodie glances backward over her shoulder. Striking sunlight cuts across her face in golden-hour warmth, strands of hair lifting in the wind. Slow push-in on a handheld 35mm frame, shallow depth of field, subtle film grain. Ambient street noise and a soft gust of wind synchronized with the hair movement.

Victorian House in Night Fog

A pale pink Victorian house stands in dense night fog, glowing with warm light from curtained windows. Slow dolly forward along the front path, volumetric fog catching the glow, cool moonlit rim light playing against the warm interiors. Distant wind chimes and muffled night ambience rise gently as the camera approaches the porch.

Floating Product Reveal

Floating modern soccer cleat with a beige textured upper and a translucent sole plate with traction studs, clean white studio background. The cleat rotates slowly in zero gravity while macro details resolve: stitching, texture grain, light refracting through the sole. Orbiting camera ends in a snap to a centered hero frame, punctuated by a clean whoosh and a click on the lock-in.

Neon City Sleeper

A person sleeps in a bed facing a large window overlooking a vibrant neon-lit cityscape at night. The camera drifts slowly from over the bed toward the glass, city lights pulsing softly across the sheets. Rain streaks the window; distant traffic and a low synth hum give the scene a calm, cyberpunk mood.

Retro Headlights Ignition

Extreme close-up of dual square headlights emitting blinding white light on a red and grey retro vehicle. The lights flare on with a mechanical clunk, lens flares blooming across chrome trim. Slow pull-back reveals wet asphalt reflections while an engine rumble builds beneath an electronic ignition chime.

Who is Seedance 2.5 for

Ad and campaign teams

A 30-second ad needs an opening, a product moment, and a closing frame. Seedance 2.5 can generate all three in a single pass with consistent product appearance and lighting throughout. Draft mode previews a take at 480p before you pay for the full-quality render, which cuts wasted generations for teams producing high volumes of variants.

Directors and filmmakers

The jump to 50 reference inputs changes what’s possible in a single generation. Supply a reference for every character in a multi-person scene and get consistent faces, clothing, and proportions across the full 30 seconds. Extension continues a finished clip from its last frame when a scene needs to run longer.

Product and e-commerce teams

Product videos need precision. Seedance 2.5 holds macro details like stitching, texture, and material across camera moves, and video-reference editing lets you change a finished clip by describing the edit instead of regenerating it. Combined with native audio sync, the output is closer to production-ready than any previous version.

Getting started with Seedance on Krea

1. Open Krea Video. Go to the Krea Video tool and pick Seedance 2.5 from the model selector. It’s available on the Pro plan and above.

2. Add your references. Upload reference images or clips to lock characters, products, and style. Seedance 2.5 raises the limit to 50 multimodal references, including video and audio.

3. Write the prompt. Describe the shot like a director: subject, camera movement, lighting, mood, and the sounds that should sync to the action. Longer, more specific prompts give the model more to work with — see tested Seedance 2.5 examples and prompts for structures worth copying.

4. Generate and refine. Generate, compare takes, then enhance and upscale the best one. Everything stays inside Krea, ready to download for social, ads, or client work, with the full walkthrough in our step-by-step Seedance 2.5 tutorial.
