What if it doesn't work out?

Which frame shapes are there?

21:9, 16:9, 4:3, 1:1, 3:4, 9:16. 9:16 suits Reels, Shorts and stories; 16:9 suits YouTube and websites.

from 5s to 15s. Pick the length in the settings before you start.

Can I use my own picture?

Yes: add up to 2 — from your computer, from the Library or as an element. The model takes them as a base or a reference.

For developers

Run this from your own code

The same request the Generate tab sends, with the settings you have chosen.

Model id:minimax-h3-max

curl -X POST https://seedara.ai/api/v1/generate \
  -H "Authorization: Bearer $SEEDARA_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{
  "model": "minimax-h3-max",
  "prompt": "Describe the shot: subject, action, camera move, lighting...",
  "params": {
    "aspect_ratio": "16:9",
    "duration_seconds": 5,
    "resolution": "768p"
  }
}'

This snippet updates as you change the form. Copy it once the settings are the ones you want.

Request parameters

What goes in `params`, by the names the API uses.

Optional

`image_urls` Input images	images	up to 1 files	—
`aspect_ratio` Aspect ratio	one of a list	`21:916:94:31:13:49:16`	16:9

How a generation runs

POST /v1/generate answers immediately with a job_id - it does not wait for the result.
Poll GET /v1/jobs/{id} until status is completed or failed.
A completed job carries output_url - the finished file.
