What is Seedance 2.5?
Seedance 2.5 is ByteDance's native audio-video model for generating a complete clip from text, one image, or a large reference set containing images, footage, and sound.
Unlike workflows that assemble several independent short clips, Seedance 2.5 can reason across a native take up to 30 seconds. That longer context helps characters, locations, camera logic, sound, and narrative beats remain connected.
Its dedicated reference workflow accepts as many as 30 images, 10 videos, and 10 audio files, with 50 files total. Visual sources can define identity and spatial layout, video can guide motion and camera language, and audio can establish dialogue, performance, or rhythm.
Seedance 2.5 also supports timestamped pacing, layout references, physically grounded fabric and hair, multilingual direction, synchronized sound, and focused scene changes such as replacing a green-screen background.
Seedance 2.5 capabilities
Use Seedance 2.5 as part of a complete AI video workflow in HighReach, from the first reference frame to final output review.
01Native 30-second takes
Direct an establishing moment, progression, camera transition, and final hold inside one generation. Timestamp ranges can allocate time to consecutive, non-overlapping actions.
02Up to 50 references
Combine character sheets, products, wardrobe, environments, blockouts, motion clips, dialogue, and music. Explicit roles prevent a large reference set from becoming an ambiguous mood board.
03Synchronized audio and motion
Write dialogue, ambience, music, effects, and silence alongside action and camera direction. Seedance generates the sound with the moving scene rather than treating it as a later attachment.
Connected production
Brief, generate, compare, and refine without losing the creative thread.
How it works
Seedance benefits from clear timing and role-based references. HighReach keeps source material, controls, output, and follow-up generations in one production view.
Use text for open exploration, an image for a fixed opening composition, or reference mode for production continuity.
Identify which files control characters, products, wardrobe, location, layout, motion, camera, dialogue, or music.
Use consecutive timestamp ranges for setup, movement, transitions, sound cues, and the final composition.
Choose 4-30 seconds at 480p or 720p, then inspect faces, physical contact, sound alignment, and transitions.
Model lineup in HighReach
Each Seedance 2.5 endpoint is designed around different source material while retaining the same duration, resolution, and review workflow in HighReach.
Create from words
Generate a complete scene from a written brief with flexible aspect ratios, native sound, and unusually long output for a direct generation.
Animate a composition
Anchor the opening shot with an uploaded image and optionally define the ending composition with a second frame.
Direct with up to 50 files
Use a large multimodal production board when identity, layout, performance, camera, or sound needs an explicit source.
Prompt playbook
A useful prompt behaves like a compact director's brief. Give every detail a job instead of stacking visual adjectives.
Timed long take
010-6s: wide tracking shot follows the dancer entering the courtyard as quiet cello begins. 6-18s: camera arcs left while coral ribbons respond naturally to her turns and percussion enters. 18-27s: push toward a medium portrait as the musicians resolve one final beat. 27-30s: hold the closing composition. One continuous take, stable identity and architecture.
Reference-rich campaign
02@Image1 defines the actor, @Image2 the exact coat, @Image3 the product, @Image4 the concrete location, @Video1 the camera pace, @Video2 the hand choreography, and @Audio1 the edit rhythm. Build one 20-second commercial scene. Preserve face, garment, label, and spatial layout throughout.
Spatial direction
03Use @Image1 as the exact 3D layout: performer begins at marker A, camera starts at marker B, and the product remains on pedestal C. Replace the blockout materials with warm limestone and late-afternoon light. Follow the marked camera path without changing object positions.

No single model is best for every shot. Move between model families while keeping your source frames and production workflow in HighReach.

Check 01
HighReach currently exposes Seedance 2.5 at 480p and 720p; broader product claims from other surfaces may not match these endpoints.
Check 02
Video and audio references are each limited to 30 seconds total in the reference workflow, even when several files are uploaded.
Check 03
Large reference sets can conflict; remove redundant inputs and clearly identify the source of truth for each detail.
Check 04
Review dialogue clarity, hands, object contact, typography, logos, and identity through every transition before publishing.
