wan2.5-i2v-preview
Wan 2.5 I2V Preview creates a video from an image and written motion direction. Ailoot exposes resolution, prompt extension and audio-related fields for the selected shot.
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 wan2.5-i2v-preview with model, image, prompt and negative_prompt. Choose resolution from 480P, 720P or 1080P using the exact uppercase values. The request also exposes prompt_extend, audio_url and audio; retain their selected values with the source image and motion brief.
Describe the action that should develop from the supplied composition and the subject details to preserve. Keep camera motion, background changes and the intended final pose distinct. Use the negative prompt for the unwanted treatment relevant to that shot. If an audio field is used, keep its actual input and selected controls with the request and review the resulting video and audio together.
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.

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 →
