## FAQ

### What is Seedance 2.5?

Seedance 2.5 is ByteDance's video generation model. It makes clips from 4 to 30 seconds with sound from a text prompt, a first frame, a first and last frame, up to 30 reference images, reference video and audio, or a video to edit, at 480p, 720p or 1080p.

### Does Seedance 2.5 have an API?

Yes. On Revana you send POST https://api.revana.si/v1/generations with "model": "seedance-2.5" and one API key, then poll the generation until it succeeds. The same key works for Seedance 2.0, Veo 3.1, Kling and every other model in the catalogue.

### How much does Seedance 2.5 cost?

On Revana, $0.09 per second at 480p, $0.21 at 720p and $0.52 at 1080p, sound included. A 5 second 720p clip is $1.05, a 10 second one $2.10 and a 30 second 1080p clip $15.60. With a video input the rate drops to $0.06, $0.15 and $0.34 a second, but the input clip's seconds are billed too.

### Can I use Seedance 2.5 for free?

Not without limits anywhere: every Seedance 2.5 API charges per second. On Revana a new account gets free signup credit (it unlocks when you save a card, which is not charged), and failed generations are never charged. Revana also runs MiniMax H3 free per clip once an account has topped up at least $10.

### Is Seedance 2.5 open source?

No. ByteDance has not released Seedance 2.5 weights. You use it through ByteDance’s own apps and API, or through an API such as Revana.

### How long can a Seedance 2.5 video be?

Any whole number of seconds from 4 to 30 in one generation, set with the duration field. Seedance 2.0 stops at 15 seconds.

### Does Seedance 2.5 make 1080p and 4K video?

It makes 480p, 720p and 1080p. For 4K, use Seedance 2.0, Veo 3.1 or Kling 3.0 through the same key.

### Does Seedance 2.5 generate sound?

Yes: set audio to true for dialogue, effects and music generated with the picture. The price is the same with sound on or off.

### Am I charged when a Seedance 2.5 generation fails?

No. The price is held when you submit and released if the job fails. Revana tries its other routes first and charges only the one that succeeds.

### Can I use Seedance 2.5 from Claude, ChatGPT or Cursor?

Yes. Add the Revana MCP server (https://revana.si/api/mcp) and ask for a video: it quotes the price, makes the clip on your credits and gives you a download link.
