Etsy listing video from one photo: Wan 3.0, 5 seconds, 63 cents

To make a 5-second listing video from one product photo, send the photo as a first frame to wan-3.0 with a one-sentence motion prompt. It costs $0.32 at 480p, $0.63 at 720p and $1.25 at 1080p on Sume. For a marketplace thumbnail-sized player, 720p is the sensible default.

The listing photo does the work of keeping your product accurate. The prompt should describe only what moves.

The request

Use frame_images with frame_type: first_frame. The model animates away from your photo instead of inventing a product, and you set duration to 5 and resolution to 720p explicitly (video generation docs). Always send the resolution: leaving it out leaves the price to the runtime default.

curl -X POST "https://api.sume.com/v1/videos" \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "wan-3.0",
    "prompt": "Slow turntable rotation of the ceramic mug on a wooden table, soft window light",
    "duration": 5,
    "resolution": "720p",
    "generate_audio": false,
    "frame_images": [{
      "type": "image_url",
      "image_url": {"url": "https://example.com/mug.jpg"},
      "frame_type": "first_frame"
    }]
  }'

What it costs

Wan 3.0 lists at $0.05, $0.10 and $0.20 per second by resolution. Sume bills list times 1.25 and rounds up to the cent (video router docs).

Settings that save a re-run

Set generate_audio to false if the listing will be silent or you will add music later. Keep motion small: a turntable, a light shift, a hand placing the item. Large camera moves are where a product's shape drifts.

Compare the first and last frame of every result against your photo before you upload. Logos and small print are the details most likely to change.

Know the limits

Sume does not edit the product inside a video, and wan-3.0 is a generator, not a guarantee of fidelity. If the item must be exact, treat the clip as a lifestyle shot and keep the still photos as the source of truth in the listing.

Practical notes

Batch behavior matters if you have a catalog. Each listing is its own job, so submit them in sequence, store the job id next to the listing id, and poll later. A shop with 40 listings at 720p spends $25.20 for one pass, so test the prompt on three listings first.

Check marketplace rules before you upload. Some require that video show the actual item, and an animated photo may or may not meet that rule for your category.
