How to Use Seedance 2.5
Steps to get you started in Wireflow.
Add a Seedance video node
On the visual canvas, drop in a Seedance video node and connect a text input. Optionally wire in a reference image from an upstream image generator node to guide the scene. The workflow on this page runs Seedance 2.5.
Write your shot prompt
Describe the scene, the characters, and any dialogue in the prompt field. Set resolution and clip length, then leave audio enabled so sound generates alongside the video.
Run and collect the clip
Run the workflow and watch the live log. When the node finishes, the canvas returns a hosted video with audio plus a per-node cost line for tracking spend.
What Seedance 2.5 Is
Seedance 2.5 is ByteDance's video generation model, unveiled in Beijing on June 23, 2026, with a public launch window that opened on July 3, 2026 as an enterprise beta rolling out through Dreamina and Jimeng. ByteDance released nothing between 2.0 and 2.5, so 2.5 is the direct successor to Seedance 2.0 and any spec sheet for an in-between version describes a release that never shipped.
The headline change is length. Seedance 2.5 generates a full 30 seconds in a single pass, so there is no stitching and no seam where two clips join. Output is native 4K at 10-bit color depth, and audio is generated in the same latent space as the video rather than added afterwards, which is what keeps sound and picture in sync natively. It accepts up to 50 multimodal reference inputs, including images, audio clips, 3D white-box models, and style references, roughly four times what Seedance 2.0 allowed. Prompt adherence is about 20 percent better than 2.0, and subjects and characters stay consistent across cuts inside the 30-second window. ByteDance offers its own Seedance 2.5 API. On Wireflow, you can run Seedance 2.5 from the canvas, the REST API, or Claude, at 27 credits a second. A 5 second clip uses 135 credits.
Seedance 2.5 Capabilities
30 Seconds in One Pass
Generates a full 30-second clip in a single pass, so there is no stitching step and no visible seam between segments.
Native 4K, 10-Bit Color
Renders at native 4K with 10-bit color depth, which leaves grading headroom that 8-bit output does not give you.
Audio in the Same Latent Space
Sound is generated in the same latent space as the video rather than bolted on afterwards, so audio and picture line up natively.
Up to 50 Reference Inputs
Takes up to 50 multimodal references: images, audio clips, 3D white-box models, and style refs. That is about four times the Seedance 2.0 cap.
Consistency Across Cuts
Holds subject and character consistent across cuts within the 30-second window, and follows prompts about 20 percent more closely than 2.0.
Chain With Other Models
Wireflow runs video models as nodes next to Flux 2 Pro, Nano Banana 2, and upscalers, so a whole pipeline executes from one endpoint.
What one Seedance 2.5 clip costs on Wireflow
Wireflow runs Seedance 2.5 and Seedance 2.0 as video nodes and bills each run in credits. Starter is $36 a month for 2,660 credits, and Professional is $59 a month for 4,370 credits.
- One 5 second Seedance 2.5 clip uses 135 credits, $1.83 on Starter or $1.82 on Professional. That is about 19 clips a month on Starter and about 32 on Professional.
- One 5 second Seedance 2.0 clip uses 90 credits, $1.22 on Starter or Professional. That is about 29 clips a month on Starter and about 48 on Professional.
Shorter clips can cost a bit more per second; you're always charged for the real length.
Run Seedance 2.5 from Claude
You can also run Seedance 2.5 from a Claude chat. Add Wireflow as a connector once:
- In Claude, open Customize, then Connectors. Click + Add and choose Add custom connector.
- Name it Wireflow and paste
https://www.wireflow.ai/api/mcpas the server URL. - Sign in to Wireflow when Claude asks, and approve the access.
The Claude app setup guide has the full steps. Then ask in plain words, for example:
Example prompt: "Use Wireflow to make a 5 second Seedance 2.5 clip of a chef plating a dessert in a busy kitchen, then make the same shot with Seedance 2.0 so I can compare them. Tell me the credit cost and wait for my yes before you run it."
With that last line, Claude looks up the price and waits for your yes before it spends any credits. Runs use the credits on your Wireflow account.
More Than Just Seedance 2.5
See What Changed From 2.0
Seedance 2.5 lifts single-pass clip length to 30 seconds, raises output to native 4K, and takes up to 50 reference inputs, roughly four times the 2.0 cap. The Seedance 2.0 page covers the previous version.
Call It From Your Code
Seedance 2.5 runs through the Wireflow REST API as well as on the canvas. The Seedance 2.5 API page shows the async submit, poll, and retrieve pattern Wireflow already uses for video.
Compare Against Kling 3
Run the same prompt through two video models in parallel branches before committing to one. Kling Video 3 has a free tier and multi-shot clips around 15 seconds, and sits a single node swap away.
One Canvas, Many Models
Seedance is one of several video options on the platform. The AI video generator lets you generate from text or images and swap engines without rewriting any integration code.
Build Visual Video Pipelines
Chain a Seedance video node with image models, upscalers, and LLM prompt steps on a canvas. The node-based video generation editor and the API run the exact same workflow definition.

Build Your Video Pipeline on Wireflow
Seedance 2.5 pricing and general API access have not been announced yet. Seedance 2.5 already runs as a node on the Wireflow canvas, wired to a prompt node next to a Seedance 2.0 node, with Kling 3 and Veo 3.1 a swap away. This workflow renders 5-second clips at 720p.
