Runs Seedance 2.0, Fast and Mini — the Seedance models our provider routes today. Seedance 2.5 joins the model list as soon as the API opens.
Seedance 2.5 AI Video Generator
ByteDance's Seedance 2.5 generates 30 seconds of synchronized audio and video in a single pass, from up to 50 reference files, with timestamp-level editing. We're integrating it — the generator above runs Seedance 2.0 today.
What's New in Seedance 2.5
Seedance 2.5 raises the ceiling on every part of the pipeline: longer single-pass output, far more references, and editing you can aim at a specific moment.
30-Second Single-Pass Output
Seedance 2.5 generates a full 30-second clip in one pass, up from 15 seconds. Multi-round extension carries that out to several minutes while holding characters, environment and narrative pacing steady.
Joint Audio-Video Generation
Audio and visuals come out of one unified multimodal architecture, so sound and picture are aligned from the first frame. Seedance 2.5 keeps that alignment across extension rounds.
30 Images, 10 Videos, 10 Audio Clips
One pass accepts up to 30 reference images, 10 video clips and 10 audio clips. That is the 50-reference figure, broken down — video and audio are first-class references, not just style hints.
Timestamp-Level Editing
Point Seedance 2.5 at a time range and change the narrative, camera, movement or rhythm inside it. Characters, actions and plot in a specific clip can be revised after the video exists.
Clay-Render Blockout
Feed in a textureless 3D model to lock spatial structure, character poses, motion paths and camera angles. Seedance 2.5 reads the blockout and derives light direction, colour temperature, intensity and shadow from it.
Green Screen & Camera Editing
Replace a background while the subject stays intact, with clothing, hair, gait and lighting responding physically. Camera movement can be re-aimed without disturbing the performance underneath.
Seedance 2.5 vs Seedance 2.0
Seedance 2.5 keeps 2.0's joint audio-video architecture and pushes length, references and editing control well past it. The Seedance 2.0 column is what the generator on this page does right now.
One continuous 30-second take replaces a stitched sequence of short shots.
Extension rounds carry characters, environment and pacing forward, so a multi-minute video holds together.
Same unified architecture in both. Seedance 2.5 adds sync that survives extension rounds.
Video and audio become reference material in their own right, not just an image board.
Editing moves from re-rolling a prompt to aiming at a moment, a subject or a camera path.
Camera position and staging can be locked before generation instead of coaxed out of a prompt.
Native 4K with 10-bit colour was the Seedance 2.0 upgrade. The Seedance 2.5 launch post states no resolution, so don't read 4K into 2.5 yet.
Seedance 2.5 appears in the model list the day our provider opens the route.

How to Use Seedance on This Page
The same workflow transfers to Seedance 2.5 when the route opens. Build it now on Seedance 2.0.
Pick a mode and a model
Choose text-to-video, image-to-video or reference-to-video, then Seedance 2.0 for maximum quality, Fast for speed, or Mini for volume.
Write the shot, not the summary
Name the subject, the action, the camera move and the light in one line. Add reference images to hold a character or a look steady across takes.
Set duration, ratio and audio
Pick 4 to 15 seconds, an aspect ratio from 21:9 through 9:16, and leave audio generation on. Finished videos land in Creations and stay there.
Can You Use Seedance 2.5 Here Yet?
Seedance 2.5 has shipped. Our upstream provider hasn't opened the route, so this page runs Seedance 2.0 until it does — and switches over the day it opens.
Released by ByteDance
The official Seed launch post documents 30-second single-pass audio-video, the 30 + 10 + 10 reference breakdown, timestamp editing and clay-render blockout.
API access is still rolling out
ByteDance lists Seedance 2.5 API access as coming soon. Until an upstream route exists, no third-party tool can honestly call Seedance 2.5 — including this one.
Live here today: Seedance 2.0
Seedance 2.0, Fast and Mini run in the generator above with text, image and reference input, 4 to 15 second clips, up to 4K on the standard tier, and audio generation on by default.

Seedance 2.5 Frequently Asked Questions
What Seedance 2.5 does, what changed since 2.0, and when you can run it here.
What is Seedance 2.5?
Seedance 2.5 is ByteDance's video generation model. It produces a 30-second clip with synchronized audio in a single pass, accepts up to 30 reference images, 10 video clips and 10 audio clips, and supports timestamp-level editing of narrative, camera, movement and rhythm.
What's new in Seedance 2.5 compared with Seedance 2.0?
Single-pass length doubles from 15 to 30 seconds and extends to several minutes across rounds. References grow to 30 images plus 10 video and 10 audio clips. Editing gains timestamp targeting, green-screen replacement, camera-perspective changes and clay-render 3D blockout.
How long can a Seedance 2.5 video be?
Thirty seconds in one pass. Longer pieces are built with multi-round extension, which carries characters, environment and narrative pacing forward so a multi-minute video stays consistent shot to shot.
Does Seedance 2.5 generate audio?
Yes. Seedance 2.5 uses a unified multimodal architecture that generates audio and video jointly, so sound and picture are aligned from the start rather than dubbed on afterwards — and stay aligned through extension rounds.
What is the clay-render reference in Seedance 2.5?
A textureless 3D model you supply to define spatial structure, character poses, motion paths and camera angles. Seedance 2.5 reads that blockout and renders realistic light direction, colour temperature, intensity and shadow on top of it.
Does Seedance 2.5 support 4K?
The official Seedance 2.5 launch post states no resolution. Native 4K with 10-bit colour was announced as a Seedance 2.0 upgrade, so treat 4K as a 2.0 spec until ByteDance publishes 2.5 resolution details.
When can I use Seedance 2.5 on this page?
As soon as our upstream provider opens the Seedance 2.5 route — ByteDance still lists API access as rolling out. The generator above runs Seedance 2.0, Fast and Mini meanwhile, and Seedance 2.5 appears in the model list the day it's available.
