Select runway-gen4-turbo in /v1/videos. The request exposes image as a string or an array of up to ten strings, prompt, end_image and five- or ten-second duration. Prepare the supplied material and written direction around one readable action and the final framing.
State which subject details the shot should preserve and what should change over time. Give the camera a clear direction and describe the intended end state. A product shot can use a gradual reveal; a character moment can use a gesture and final pose. Keep the chosen input image, optional end image and motion brief together for comparison with the finished clip.
Submit the shot once through /v1/videos, retain the returned request ID and poll that original operation through /v1/videos/{request_id}. Save every completed video output and the complete response before reviewing the action, framing and end state against the brief.

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.
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 →
