Which Sume video model lists 4K?

The video docs say gemini-omni-flash-1.1 accepts 3 to 10 seconds at 360p, 720p, 1080p and 4K, in 16:9 or 9:16, with native synced audio and image or video references. The resolution list is per model, so check supported_resolutions in the catalog before you pin it.

What does the request look like?

Set resolution to the tier and aspect_ratio to a listed ratio. Do not send size; it returns 400 unsupported_parameter because every v1 model reports supported_sizes: null.

curl -X POST https://api.sume.com/v1/videos \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: shopify-4k-001" \
  -d '{
    "model": "gemini-omni-flash-1.1",
    "prompt": "Ceramic mug rotating on a white sweep, soft studio light",
    "resolution": "4K",
    "aspect_ratio": "16:9",
    "duration": 8
  }'

How do I confirm the pixel size?

The docs name a tier, not a pixel count. Extract a still from the delivered clip with video frames, read its width and height, and compare them to 3840x2160 before you upload. The docs also say higher resolutions take longer and cost more.
