How to call the SVI 2.0 Pro API

SVI 2.0 Pro runs through POST /v1/videos/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Get an API key from the EmpirioLabs dashboard.

cURL: submit the job
curl https://api.empiriolabs.ai/v1/videos/generations \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "svi-2-0-pro",
    "prompt": "Describe what you want SVI 2.0 Pro to generate."
  }'
cURL: poll for the result
curl https://api.empiriolabs.ai/v1/jobs/JOB_ID \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY"
Python
import requests

response = requests.post(
    "https://api.empiriolabs.ai/v1/videos/generations",
    headers={"Authorization": "Bearer YOUR_EMPIRIOLABS_API_KEY"},
    json={
        "model": "svi-2-0-pro",
        "prompt": "Describe what you want SVI 2.0 Pro to generate.",
    },
)
job = response.json()

# Generation runs as an async job. Poll until it completes.

Good to know

Theoretically infinite-length video with consistent character ID. Image-to-Video typically yields superior results to text-to-video.

Constraints

  • Generation can take 45+ minutes for long videos
  • For best motion: describe consecutive actions per segment in your prompt

Image formats

  • jpg, jpeg, png, webp, heic, heif, bmp, tiff, tif

Multi-scene mode

  • When describing several scenes in one prompt, lower CFG (1.0-1.3) gives the model more freedom to interpret distinct scene transitions
  • Raise CFG (1.5-2.0) when each scene must follow the prompt literally
