Why Choose Seedance 2.0 API on Kie AI Platform

Seedance 2.0 and 2.0 Fast on One Endpoint

bytedance/seedance-2 and bytedance/seedance-2-fast run on POST /api/v1/jobs/createTask with the same request fields. Seedance 2.0 adds higher resolutions, while 2.0 Fast stops at 720p, the default for both. Pricing for each resolution, with or without video input, is shown in the pricing card above.

First Frames and References Do Not Mix

First-frame image-to-video, first-and-last-frame image-to-video and multimodal reference-to-video cannot be used together, so do not combine first_frame_url or last_frame_url with any reference field. When the first and last frames must match your images exactly, use first-and-last-frame image-to-video.

Audio Is On by Default, and 4K Is H.265

Audio is generated by default; set generate_audio to false to turn it off. At the highest resolution, output is encoded as H.265 (HEVC), so make sure your player or pipeline supports it. Pass a callBackUrl to receive the result when the task finishes, verify each callback with the HMAC signature described in the Kie.ai webhook guide, and query Get Task Details for the authoritative result. New Kie.ai users receive 80 free credits for testing.

Dreamina’s Seedance 2.0 is ByteDance’s multimodal AI video generation model designed to create cinematic, multi-shot videos with synchronized audio from mixed inputs such as text, images, video clips, and music.

Seedance 2.0 API adds multimodal input, native audio-video generation, and stronger multi-shot consistency. It can combine text, images, video, and audio references to replicate motion, camera style, and rhythm while keeping characters stable across scenes.

Unlike standard tools that rely mainly on prompts, seedance 2.0 api uses reference video, images, and audio to control motion, camera behavior, and style. This approach improves consistency, reduces character drift, and delivers more production-ready results.

Seedance 2.0 Fast can be understood as a more efficient version of Seedance 2.0, designed for faster generation and lower cost. Seedance 2.0 API focuses more on quality, control, and production-ready video output, while Seedance 2.0 Fast API is better suited for rapid iteration, frequent testing, and scalable video generation workflows.

Seedance 2.0 is billed per second. Without video input, Seedance 2.0 costs 19 credits ($0.095) per second at 480p, 41 credits ($0.205) at 720p, 102 credits ($0.51) at 1080p and 208 credits ($1.04) at 4K. Seedance 2.0 Fast costs 11.7 credits ($0.059) per second at 480p and 24.8 credits ($0.124) at 720p. With video input the per-second rate is lower, but input and output seconds are both billed: from 11.5 credits ($0.0575) for Seedance 2.0 and 6.8 credits ($0.034) for Seedance 2.0 Fast at 480p. Seedance 2.0 prices are currently in beta and may change. Prices may be updated; the pricing card at the top of this page always shows the current rate.

For the lowest cost, Seedance 2.0 Mini starts at 2.4 credits ($0.012) per second. Seedance 2.0 Fast stops at 720p and suits quick, low-cost iterations, while Seedance 2.0 adds 1080p and 4K output. For clips longer than 15 seconds, Seedance 2.5 generates 4–30 second videos at up to 1080p. ByteDance's newer Seedance 2.5 Flash covers faster 480p and 720p generation of up to 30 seconds.

Sign in to Kie.ai and create a key on the API Key page (kie.ai/api-key), then send it in the Authorization: Bearer YOUR_API_KEY header. Each key can have its own hourly, daily and total usage caps and an IP whitelist. Seedance 2.0 runs as the model bytedance/seedance-2 and Seedance 2.0 Fast as bytedance/seedance-2-fast, both on POST https://api.kie.ai/api/v1/jobs/createTask. Keep the key on your server and never expose it in browser or mobile app code.

The API reference is at docs.kie.ai/market/bytedance/seedance-2, and Seedance 2.0 Fast has its own page at docs.kie.ai/market/bytedance/seedance-2-fast. Generation is asynchronous: createTask returns a taskId, and a 200 response only means the task was created. Pass a callBackUrl to be notified when it finishes, or poll GET /api/v1/jobs/recordInfo?taskId=… until the state is success or fail. Any other code in the response means the request failed, for example 401 for an invalid or missing API key, 402 for insufficient credits or 429 when the rate limit is exceeded. Generated files are kept for 14 days, so download the videos you want to keep.

Seedance 2.0 API accepts up to 9 reference images, 3 reference videos and 3 reference audio clips in one generation. Each video or audio clip must be 2–15 seconds long, and the total length of all videos, and of all audio clips, cannot exceed 15 seconds. Reference inputs cannot be combined with first_frame_url or last_frame_url. Using mixed references helps define character appearance, motion patterns, and editing rhythm more precisely.

Yes. Seedance AI API includes native audio support that can align dialogue, rhythm, and sound effects with on-screen motion. This enables lip-sync, beat-matched editing, and more realistic audiovisual storytelling for marketing or creative content.

Seedance V2 API (Seedance 2.0 and Seedance 2.0 Fast) accepts a duration of 4–15 seconds per clip (default 5), or -1, in which case billing follows the length actually generated. Resolution is 480p, 720p (default), 1080p or 4K on Seedance 2.0, and 480p or 720p on Seedance 2.0 Fast. Aspect ratio can be 1:1, 4:3, 3:4, 16:9 (default), 9:16, 21:9 or adaptive.

You can test Seedance 2.0 API on Kie AI using the built-in Playground. New users receive free credits to try Seedance 2.0 AI video generation, upload references, and preview results before integrating the Seedance AI API into production workflows.

You can create realistic human videos with Seedance 2.0 API on Kie AI by describing the character, motion, and scene clearly, or by using image references to guide appearance. This helps improve human consistency, natural motion, and overall video realism.
