12 course module intros as 15-second avatar videos: $33.12

A 12-module course needs 12 short intros, and with one Sume avatar they cost $33.12 on standard, $44.10 on plus and $99.00 on max at 15 seconds each. Add $0.95 once for the avatar. Each module is its own job, so you can re-render one intro without paying for the other eleven.

What it costs

Rates are per second of the finished video, without a product image. 15 seconds x 12 modules = 180 billable seconds. Avatar rates are Sume's charged per-second tier rates from the repo rate card (standard $0.184, plus $0.245, max $0.55 without a product image); confirm them in GET /v1/catalog.

Submit all twelve

Use the canonical POST /v1/avatar-1.0/talking-video route with the same avatar_handle. Give each module a stable Idempotency-Key so a rerun of your script does not create duplicates. Poll the jobs afterwards.

import os, requests

H = {"Authorization": f"Bearer {os.environ['SUME_API_KEY']}", "Content-Type": "application/json"}
modules = {
    1: "Welcome. In this module you will set up your project.",
    2: "In module two we cover the data model.",
    # ... one script per module, each about 15 seconds when spoken
}

for n, script in modules.items():
    body = {"avatar_handle": "course_host", "script": script,
            "quality": "standard", "aspect_ratio": "16:9"}
    r = requests.post("https://api.sume.com/v1/avatar-1.0/talking-video",
                      headers={**H, "Idempotency-Key": f"course-intro-module-{n}-v1"},
                      json=body, timeout=60)
    r.raise_for_status()
    print(n, r.json()["data"]["request_id"])

Limits and gotchas

• Sume estimates duration from the script: keep each intro well inside the 4 to 60 second window.
• aspect_ratio supports 1:1, 3:4, 9:16, 4:3 and 16:9 (default 9:16). The resolution is 720p.
• For Korean course intros, choose a Hangul caption style if you turn on inline captions, or Sume rejects the request.
• Preview the first frame of one module before you render all twelve; see the preview guide.
