Choose this model for

Test one product-shot idea
Use a short brief with one subject and one movement, as in the red-shoe example below. This tests whether the scene follows your direction; a text-only shoe is a concept, not a verified image of a real SKU.
Budget ten-second scene variants
Set duration and resolution explicitly before comparing several scene ideas. Budget each ten-second output at ten times its per-second resolution tariff.

Alternatives

Kling 3.0
Choose Kling when an explicit generated-audio switch is required. Compare its matching duration, resolution and audio tier rather than its starting price.
Veo 3.1 Lite
Consider Lite when a fixed eight-second text-only shot is enough. Its whole-generation tariff has a different duration basis from this ten-second example.

What does a ten-second 720p video request cost?

Current USD catalog examples: duration × the 720p rate. Supported durations start at six seconds; a ten-second request is not priced as eight seconds. These are request costs, not a measured cost per approved clip.

Request configurationCost (USD)
One ten-second 720p request$0.26
Four separate ten-second 720p attempts$1.04

Get your first result

  1. Create an account and API key. Keep the key on your server, outside browser code.
  2. Top up your balance to cover the request price.
  3. Use the playground or the API quick start above. Use the explicit inputs shown above. Poll the returned task ID until completion, then inspect the whole clip for shape changes, unwanted graphics and camera movement. Do not create a replacement task just to check progress.

Check progress with the returned taskId. Creating a new task charges for another request.

1curl https://api.api-stock.com/api/v1/task/status/YOUR_TASK_ID \

The task response reference covers results, errors and webhooks.

Recorded result

First output, 15 October 2026: ten seconds, 720p. The returned file includes audio. Check the shoe's shape through the clip; one example does not establish a model quality ranking. Inputs and method

Limits and test notes

  • The recorded output contains an audio stream although the request has no audio switch. A workflow requiring silence needs a separate audio-removal step or a model with explicit audio control.
  • Inspect the shoe's silhouette throughout the sample. One text-only output does not test preservation of a real product, repeated-run reliability or typical latency.

Frequently asked questions

Does a finished task mean the clip is ready to publish?

No. Completion means a result was produced. Inspect details, unwanted graphics and motion against your brief. A product campaign also needs comparison with the real product; a text-only prompt cannot preserve an unseen item.

How do I budget for more than one attempt?

Multiply the price of the exact request by the number of generations. Measure how many outputs you approve in your own pilot before projecting a production budget; these samples do not establish an approval rate.
