Seedance 2.0 API: Make Product Short Videos

Short product videos — a 5-second spin for a product page, a looping hero for an ad, a social teaser — used to mean a shoot or a motion-graphics pass. With the Seedance 2.0 API you generate them from a prompt, or from a product photo you already have. This tutorial walks both paths end to end on hiapi: a text-to-video product reveal, and an image-to-video clip that animates a static packshot — each a real generated video with its prompt, parameters, and task ID.

There are two ways into a product clip, and they share one API call:

• Text-to-video — describe the shot. Best when the product is flexible or you are exploring a look.
• Image-to-video — hand Seedance a product still as the first frame and it animates that. Best when the product must match an asset you already own.

Path 1: text-to-video product reveal

Describe the product, the camera move, and the lighting. Seedance handles the motion — here, a sneaker on a turntable under a sweeping spotlight.

A premium athletic sneaker slowly rotating on a glossy black turntable,
dramatic studio spotlight sweeping across the mesh and sole, subtle
reflections on the floor, high-end product commercial, clean dark background.

• Model: seedance-2-0 · aspect_ratio: 16:9 · duration: 5 · resolution: 720p · Task ID: tk-hiapi-01KVSPB1P7DNXSF5TB0Y03NYJ2 · Cost: $1.65
• What to copy: lead with the motion ("slowly rotating on a turntable") and the light ("spotlight sweeping across"). Naming the camera and light is what separates a product commercial from a static render.

Path 2: image-to-video from a product photo

This is the one most brands want: you already have a clean packshot — animate it. Pass the image as first_frame_url and Seedance moves from that exact frame.

Start with a still you already own:

Then animate it — a slow push-in with a light sweep and a wisp of steam:

{
  "model": "seedance-2-0",
  "input": {
    "prompt": "Slow cinematic push-in on the product with a soft light sweep moving across its surface, a gentle wisp of steam rising, keep the product still and centered",
    "first_frame_url": "https://static.hiapi.ai/blog/gpt-image-2-product-image-api/white-bg-packshot.jpg",
    "aspect_ratio": "1:1",
    "duration": 5,
    "resolution": "720p"
  }
}

• Model: seedance-2-0 · aspect_ratio: 1:1 · duration: 5 · resolution: 720p · Task ID: tk-hiapi-01KVSPFPMAR1MYH6Z3D9ER544N · Cost: $1.65
• What to copy: the product in the output is the product from your still — the model preserved its exact shape and color. Keep the prompt to motion only ("push-in", "light sweep", "keep the product still") so it animates rather than redesigns.

What it costs

Both clips above are 5-second 720p renders at $0.33/s = $1.65 each. Seedance is billed per second by resolution:

Resolution	Per second	5-second clip
480p	$0.15	$0.75
720p	$0.33	$1.65
1080p	$0.823	$4.115

For a product line, the workflow that keeps the bill down: prototype the motion at 480p ($0.75 a clip), lock the prompt and camera move, then re-render the keepers at 720p or 1080p. For a batch run, pass a callback instead of polling each task.

Then animate your own products on the Seedance 2.0 model page — start with a packshot you already have.
