What is the Seedance 2.5 API?
The Seedance 2.5 API is a developer-friendly endpoint for generating cinematic AI video with ByteDance's Seedance 2.5 model. Send a text prompt, a still image, or a reference clip, and get back a finished video — multiple shots, synchronized native audio, and resolution up to 4K — from a single request.
It runs the same model that powers the live generator on this page, so you can storyboard a shot in the browser and ship the identical workflow in code. Generation is asynchronous and simple: submit a job, poll until it is ready, then download a publish-ready MP4. There is no render farm to manage, no separate audio pass, and no stitching short clips together by hand.
Seedance 2.5 is built for people who need real output, not just demos — marketing teams, social creators, product studios, and app developers who want cinematic video on tap. Each render is billed per generation in credits with transparent per-second pricing, and new accounts get free starting credits so you can test with real prompts before wiring it into production.
One Seedance 2.5 API call can accept text, images, video, and audio references together, supports clips of roughly 5 to 15 seconds, and returns multi-shot scenes with camera movement and sound already in place — no timeline editor required.

Cinematic 4K Output
Render up to 4K with film-grade lighting, motion, and detail, ready to drop into a real edit.
Native Audio, Built In
Dialogue, sound effects, and ambient tone generate with the video, so there's no syncing or stock-audio step.
Multi-Shot Storytelling
Describe a scene with several shots and Seedance 2.5 cuts between camera angles in a single render.
Text, Image & Video Inputs
Start from a prompt, animate a still image, or extend a reference clip without switching tools.
One API Call
Send a request to the Seedance 2.5 API, poll for status, and pull back a finished video URL.

Seedance 2.5 vs Seedance 2.0
Seedance 2.5 builds on Seedance 2.0 with two headline upgrades: output up to 4K, where 2.0 topped out at 1080p, and generation speeds that move closer to real time. Everything creators relied on in 2.0 — native audio, multi-shot scenes, and realistic motion — carries straight over.
If you already integrated Seedance 2.0, the 2.5 API keeps the same submit-and-poll workflow, so upgrading is mostly a model-id change. You get sharper, longer-lasting detail for premium ads and large-format screens without rewriting your pipeline.
