What is Seedance 2.5?

Seedance 2.5 is ByteDance Seed’s next-generation audio-video creation model, officially announced on July 31, 2026. It builds on the unified multimodal audio-video architecture introduced with Seedance 2.0 and focuses on longer storytelling, stronger reference understanding, and more precise generation and editing controls.

According to ByteDance Seed, one generation can produce a clip up to 30 seconds and can be extended for longer narratives. The model can accept up to 30 images, 10 video clips, and 10 audio clips as references in one request, using them to understand subjects, scenes, composition, movement, camera language, style, and sound. Those are official model capabilities, not the controls currently exposed by Nano Banana Pro.

Nano Banana Pro has not yet connected a Seedance 2.5 task route. This landing page provides a fact-checked model guide and a temporary Seedance 2.0 workspace so creators can prepare prompts and understand the existing video interface. Always check the model name and point estimate shown inside the workspace before submitting.

03 / Capabilities

Key Seedance 2.5 capabilities

The official release focuses on complete stories, richer references, and production-oriented control.

01

30-second storytelling

Generate up to 30 seconds in one pass with improved transitions, scene changes, audiovisual continuity, and support for extending the result.

02

Multimodal reference input

Combine images, video clips, and audio clips so the model can follow characters, props, composition, motion, style, camera language, voices, and sound.

03

Joint audio-video generation

Plan visuals and sound together, including dialogue, ambience, effects, music, timing, and how audio supports the narrative.

04

Timestamp-level direction

Write prompts in timed segments to control when actions, camera changes, dialogue, and story beats happen within a clip.

05

Reference-based editing

Use targeted instructions to revise characters, actions, shots, or plot details while aiming to preserve continuity around the edited segment.

06

Professional scene control

Official examples include clay-model or white-model control, green-screen editing, camera-perspective editing, blocking, and complex production workflows.

04 / Scene ideas

Where Seedance 2.5 can fit

The official release focuses on complete stories, richer references, and production-oriented control.

Advertising previsualization

Plan longer product stories, camera blocking, sound cues, and transitions before committing to a physical shoot.

Short narrative development

Explore scenes with multiple story beats, characters, locations, dialogue, and audiovisual continuity in one generated sequence.

Reference-controlled campaigns

Use approved brand images, motion references, audio, and style material to communicate a more specific creative direction.

Education and demonstration

Turn processes, historical scenes, scientific concepts, or equipment workflows into structured audiovisual explanations.

Vertical fashion and lifestyle stories

Structure mobile-first scenes around wardrobe continuity, controlled movement, texture, and sound rather than a single static pose.

Location and time transitions

Plan repeated subjects, props, travel direction, and audio bridges across several environments or times of day.

05 / Prompt lab

Seedance 2.5 prompt frameworks

These prompts are structured for the newer model, but the buttons currently load them into the temporary Seedance 2.0 workspace for editing.

SCENE 01text to video

One-take brand story

Organize a continuous commercial scene into timed beats without relying on abrupt cuts.

View prompt
16:9 cinematic one-take product story. 0–5s: macro view of a ceramic tea cup as morning steam catches warm window light. 6–10s: the camera pulls back and follows a craftsperson carrying the cup through a quiet studio. 11–15s: circle around the table as ingredients and tools come into view. Keep the same cup, hands, lighting direction, and spatial continuity. Natural room ambience, subtle ceramic sounds, no subtitles or logos.
SCENE 02image to video

Reference-led character shot

Use an authorized image as the visual anchor and describe only the intended motion and sound changes.

View prompt
Preserve the identity, clothing, color palette, and environment from the uploaded image. The subject turns toward the window, takes two natural steps, and gently opens the curtain as the camera makes a slow lateral move. Maintain facial structure and room geometry. Add soft fabric movement, distant city ambience, and a quiet breath; avoid cuts, extra people, and text.
SCENE 03text to video

Timed dialogue sequence

Align performance, camera, and audio cues by giving each section a clear time window.

View prompt
Naturalistic short drama, consistent characters and location. 0–5s: medium two-shot in a rainy station café; one character says softly, “You came back.” 6–10s: slow push toward the second character as they answer, “Only for tonight.” 11–15s: hold the silence while a train passes outside and window reflections move across their faces. Accurate lip sync, restrained acting, rain and train ambience, no background music.
SCENE 04text to video

Reference-led fashion sequence

Plan a vertical editorial scene that protects wardrobe, identity, and material details across timed beats.

View prompt
9:16 fashion editorial in one continuous take. 0–4s: full-body portrait beneath a rain-lit arcade, silver coat and black boots clearly visible. 5–9s: the subject walks toward camera while reflections ripple across the floor. 10–15s: camera passes beside the subject and reveals a neon street beyond. Preserve face, garment construction, accessories, and walking direction; restrained fabric motion, rain ambience, distant traffic, no captions or brand marks.
SCENE 05text to video

Location change with visual continuity

Use time blocks, repeated props, and sound bridges to hold a story together across an environment change.

View prompt
Cinematic narrative with one recurring red bicycle. 0–5s: sunrise on a quiet coastal lane as a rider enters frame. 6–10s: match the wheel rotation into a crowded afternoon market, keeping rider, bicycle geometry, and travel direction consistent. 11–15s: emerge onto a blue-hour bridge and settle into a wide rear view. Natural wheel and chain sound, market ambience blending into river wind, no logos, no abrupt cuts.

Review before publishing

Availability, limits, and responsible use

Seedance 2.5 is not yet available as a Nano Banana Pro task route. The embedded workspace currently selects Seedance 2.0, which has different duration, reference, quality, and pricing controls. A prompt loaded from this page does not change the selected model into Seedance 2.5.

ByteDance Seed notes that physical plausibility in complex motion and stability in scenes with multiple interacting subjects can still improve. Generated people, hands, objects, subtitles, dialogue, timing, and sound may be inaccurate. Review the entire video and soundtrack before publication or client delivery.

Only upload material you are authorized to use. Do not use generated video for deceptive impersonation, harassment, privacy violations, intellectual-property infringement, or false evidence. Model access, API support, quotas, safety rules, and pricing can change; the official ByteDance source and the live Nano Banana Pro interface remain authoritative for their respective services.

07 / FAQ

Seedance 2.5 FAQ

Can I generate with Seedance 2.5 on Nano Banana Pro now?
Not yet. This page documents Seedance 2.5, but the embedded workspace currently opens Seedance 2.0. Do not submit a task expecting Seedance 2.5 unless that exact model name appears in the live selector.
Why does the page open Seedance 2.0?
The Seedance 2.5 task route has not been connected to Nano Banana Pro. Seedance 2.0 is used temporarily so users can explore the existing video workflow and prepare prompts.
How long can Seedance 2.5 generate?
ByteDance Seed states that Seedance 2.5 can generate up to 30 seconds in a single pass and supports extensions. Nano Banana Pro’s current Seedance 2.0 workspace has different duration controls.
What reference materials does Seedance 2.5 support?
The official launch describes up to 30 images, 10 video clips, and 10 audio clips in one request. The current workspace on this page does not expose that full Seedance 2.5 reference workflow.
Does Seedance 2.5 generate audio?
Yes. ByteDance presents it as a joint audio-video generation model that can coordinate dialogue, ambience, effects, music, and visual events.
Does this page list Seedance 2.5 pricing?
No Seedance 2.5 point price is claimed before integration. Any point estimate currently shown belongs to the live model selected in the workspace, initially Seedance 2.0.
Is Nano Banana Pro an official ByteDance product?
No. Nano Banana Pro is an independent multi-model platform. ByteDance, Seed, and Seedance names and trademarks belong to their respective owners.
How should I structure a Seedance 2.5 prompt?
Write the aspect ratio and visual intent first, then divide the clip into time blocks. For each block, state subject action, camera movement, light, sound, and the continuity details that must not change.
Can I prepare vertical video prompts on this page?
Yes. Use a 9:16 composition and describe full-body framing, safe space for interface overlays, movement direction, and the final hold. The current preview workspace still uses the temporary Seedance 2.0 route.
