Seedance 2.5: price, API and how to try it

Seedance 2.5 at a glance

Seedance 2.5 price (November 2026)

Seedance 2.5 is billed per second of video. Sound is included. The table shows the rate and what common clip lengths cost. Each price is held from your prepaid credit when you submit and charged only if the clip is delivered.

A job that takes a video as input (video to video, or reference clips) is billed at the lower video-input rate, and the input clip’s seconds are billed with the output: a 10 second 720p clip made from a 10 second video is billed as 20 seconds, $3.00. A first frame can cost a little more than the listed rate, so ask POST /v1/generations/quote for the exact price of a request; quotes are free.

Seedance 2.5 price at other APIs

Listed prices per second for a 16:9 clip with sound, checked up to 31 October 2026. An API is shown only at the resolutions where its listed price is above Revana’s; a dash means it lists that setting at or below Revana’s price or not at all.

Can you use Seedance 2.5 for free?

Not without limits. Every Seedance 2.5 API charges per second, and the “free” Seedance 2.5 sites give a few trial credits. What you can get for free on Revana:

• Signup credit. A new account gets free credit to try Seedance 2.5. It unlocks when you save a card; saving the card does not charge it.
• Failed generations are free. A job that fails costs nothing, so you never pay for a refusal or a timeout.
• Free quotes. POST /v1/generations/quote tells you the exact price before you spend anything.
• A free video model. Revana runs MiniMax H3 for free on its own GPUs, for drafts before you render the final take on Seedance 2.5 (it needs a first top-up of at least $10, which stays your credit). More in Can you use Seedance 2.5 for free?

The cheapest way to iterate is a 4 to 5 second 480p draft ($0.45 for 5 seconds), then the final at 720p or 1080p once the prompt works.

Seedance 2.5 API: make a video in one request

Create a key at revana.si, then send POST /v1/generations. The answer is a generation id; poll it until status is succeeded and download the file. This 10 second 720p clip with sound costs $2.10; max_cost_usd is the most you allow it to cost.

Every field, the error codes and retries are in the API docs and llms.txt. The Seedance 2.5 model page has a live price calculator and the request for every setting.

From Claude, ChatGPT, Cursor or Codex: add the Revana MCP server (claude mcp add --transport http revana https://revana.si/api/mcp) and ask for a Seedance 2.5 clip in plain words. It quotes first and spends only what you approve.

Seedance 2.5 modes, with example requests

Every mode uses the same POST /v1/generations call; only the input changes. References are public https links, or files you upload with POST /v1/uploads.

Text to video

Write the shot like a director: subject, action, camera, light, then the sound. Seedance 2.5 follows numbered shots inside one prompt, so a 15 to 30 second clip can hold several cuts.

{
  "prompt": "Shot 1: wide aerial of a lighthouse at dawn. Shot 2: the keeper climbs the spiral stairs, handheld. Shot 3: the lamp turns on, lens flare. Waves, wind, a low cello.",
  "duration": 20,
  "resolution": "720p",
  "audio": true
}

Image to video (first frame)

Pass image_url and the clip starts on exactly that picture: a product shot, a character, a storyboard frame.

{
  "prompt": "The sneaker rotates slowly as the studio light sweeps across it",
  "image_url": "https://example.com/sneaker.jpg",
  "duration": 6
}

First and last frame

Add end_image_url and the clip moves from one picture to the other. Use the same image twice for a seamless loop.

{
  "prompt": "Day turns to night over the city skyline, lights come on",
  "image_url": "https://example.com/day.jpg",
  "end_image_url": "https://example.com/night.jpg",
  "duration": 8
}

Reference to video

Up to 30 reference images (image_urls), 10 reference clips (video_urls) and 10 sounds (audio_urls) keep a character, a product, a style or a camera move the same across shots. Name them in the prompt by their order.

{
  "prompt": "The woman in image 1 walks through the shop in image 2 holding the bottle from image 3, camera follows from behind",
  "image_urls": [
    "https://example.com/woman.jpg",
    "https://example.com/shop.jpg",
    "https://example.com/bottle.png"
  ],
  "duration": 12,
  "audio": true
}

Video to video

Give a clip in video_urls and describe the change: restyle it, swap the setting, or extend the scene. Billed at the video-input rate, $0.15 a second at 720p, for the input and output seconds.

{
  "prompt": "Same shot, but the street is covered in fresh snow at night",
  "video_urls": [
    "https://example.com/street.mp4"
  ],
  "duration": 8
}
