## [Vidu Q1 Reference](https://ailoot.ai/models/en/vidu-q1-reference/)

Vidu Q1 Reference combines a written video brief with optional image references and an end image. Choose framing, resolution and a four- or eight-second duration through Ailoot.

About the model

This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below.

Use vidu-q1-reference with model and prompt at /v1/videos. The request exposes image as a string or an array of up to ten strings, end\_image, aspect\_ratio, duration and resolution. Choose four or eight seconds, 360p, 720p or 1080p, and 16:9, 1:1 or 9:16 framing.

Describe a scene that keeps the reference subject identifiable. When supplying images, identify the role of each reference and the subject details to retain. Give the action and camera direction separate instructions, then define the end pose or framing. Keep the selected images, prompt and optional ending image with the request so the completed video can be compared with the same material.

Submit the shot once through /v1/videos and keep the returned request ID. Poll that same operation through /v1/videos/{request\_id}, then save every completed video output and the complete response. Review the full action and final composition against the supplied material and brief.

### Pricing

##### How the final charge is calculated

The displayed rates estimate the cost before generation. The final charge is calculated from the cost recorded for the original generation. Measured output duration and forecast quantities are not the final billable quantity.

Tariff references do not add request options. Supported parameters are listed for the selected method.

Fast mode

Not specified When fast mode is selected

Flex mode

Not specified When flex mode is selected

Maximum reasoning effort

Not specified When maximum reasoning effort uses the default adjustment

#### Estimated rates for comparison

#### Prices by configuration

Match each charge to the conditions shown. Use one rate for each set of alternative configurations.

| ConfigurationEstimated generation cost | Rate schedule— | Forecast quantityone generation estimate | Billing quantity— | Charge Output · Estimated generation cost · Estimate for comparison only **$0.8** estimate before generation This estimate is not an additional charge or a fixed rate for the completed generation. |

Ailoot reserves an estimated amount before a request. After the result, it settles the final charge from measured usage. Streaming settlement uses the final usage record. [How reservation and settlement work →](https://ailoot.ai/docs/en/billing/reserve/)
