ByteDance's newest AI video model, with native synchronized audio and advanced multi-shot narrative that holds character, style, and environment consistent from a single text prompt.

We've run 750+ seedance 2.1 generations internally while building Wireflow and identified the three factors that separate high-quality AI outputs from generic ones — and built them directly into this workflow.
What Seedance 2.1 Is
Seedance 2.1 is ByteDance's newest AI video generation model and the official successor to Seedance 2.0, built on the same unified multimodal foundation. The headline upgrade is roughly a 20 percent jump in overall visual quality, with better rendering stability, more realistic textures, and fewer artifacts. It outputs up to 1080p and as high as 2K with a cinematic look, and it generates ambient sound, sound effects, and character dialogue in the same pass as the video, so there is no separate dubbing or audio post step.
Its other defining strength is multi-shot narrative. From a single text prompt it can produce a sequence of shots that holds character, style, and environment consistent across changing camera angles. Prompt comprehension is strong, turning complex instructions of up to about 2,000 characters into a coherent storyboard, and it also accepts a reference image as input. ByteDance exposes the model through Dreamina, CapCut, and its enterprise clouds, while most developers outside China reach it through third-party API providers.
Seedance 2.1 Capabilities
Native Synchronized Audio
Generates ambient sound, sound effects, and character dialogue in the same pass as the video, removing any separate dubbing or audio post step.
Multi-Shot Consistency
Holds character, style, and environment stable across changing camera angles, producing a coherent multi-shot sequence from a single prompt.
Up to 1080p and 2K
Renders short clips at up to 1080p and as high as 2K, with a cinematic look and improved texture realism.
Text and Image Input
Accepts complex text prompts of up to about 2,000 characters as well as a reference image to guide the generated scene.
Roughly 20% Quality Jump
Improves overall visual quality by about 20 percent over Seedance 2.0, with better rendering stability and fewer visible artifacts.
Chain With Other Models
Runs as one node next to Flux 2 Pro, Nano Banana 2, and upscalers on Wireflow, so a whole pipeline executes from one endpoint.
More Than Just Seedance 2.1
See What Changed From 2.0
Seedance 2.1 builds directly on its predecessor with a roughly 20 percent quality gain. The Seedance 2.0 page covers the prior model's specs and prompt behavior for a side-by-side read.
Call It From Your Code
Prototype the clip on the canvas, then ship the same pipeline as a REST endpoint. The Seedance 2.1 API page documents the async submit, poll, and retrieve pattern for production apps.
Compare Against Kling 3
Run the same prompt through two video models in parallel branches before committing to one. Kling Video 3 sits a single node swap away inside the same workflow for direct comparison.
One Canvas, Many Models
Seedance 2.1 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 Seedance 2.1 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.

Create With Seedance 2.1 on Wireflow
Drop Seedance 2.1 onto a visual canvas, wire it to image and prompt nodes, and run the whole pipeline in one click. Native audio, multi-shot output, and per-node cost reporting are built in, with Kling 3 and Veo 3.1 a swap away.
