Crowdfunding intro video: preview first, render at Max

For a crowdfunding intro, create the preview at standard, iterate on the first frame with regenerate, then call generate-video with quality: "max" so only the final render is billed at the top tier. A 30-second Max render costs $16.50, against $5.52 on Standard and $7.35 on Plus.

The override is documented in Sume's avatar video previews guide, read 2026-10-04: structural fields stay fixed, only quality may change, and admission, reservation and billing use the effective tier. That guide does not state a price for the preview itself, so confirm it in GET /v1/catalog before you plan a loop of many previews.

The loop

A campaign video is judged on its first seconds, so the first frame matters. Use previews to pick the frame, not to test the script: a script change is a structural change and needs a new preview.

What the final render costs

The render is per second at the effective tier. With no product image:

Override at the final step

Send an empty body to keep the tier chosen at create, or send quality to override it.

curl -X POST https://api.sume.com/v1/avatar-video-previews/$PREVIEW_ID/generate-video \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: crowd-intro-render-001" \
  -d '{"quality": "max"}'

Be straight with backers

Do not present a generated presenter as a founder or a real customer. If the avatar is made from a real person's photo, get that person's permission first. Say in the clip, the caption or the page around it that the presenter is AI-generated; the API does not add that label for you.
