Ailoot exposes 720P resolution, duration and audio-related fields for the shot. - [**Ailoot Ultra · Video** `POST /v1/videos` `wanx2.1-i2v-plus`](https://ailoot.ai/models/en/wanx2-1-i2v-plus/#method-0) About the model This description covers the model’s capabilities. Available in Ailoot inputs, outputs and options are listed for the selected method below. Select wanx2.1-i2v-plus with model, image, prompt and negative\_prompt at /v1/videos. Supply image using the documented input form for this exact profile. Resolution is 720P and the duration field defaults to five seconds; prompt\_extend, audio\_url and audio are also exposed. Describe the movement that should develop from the source image, including the desired end pose or framing. Keep the subject details to preserve separate from camera direction and background changes. Use the negative prompt for the unwanted treatment relevant to the brief. Retain the original image and any audio input with the selected settings for review of the finished clip. 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. **Ailoot Ultra · Video** `POST /v1/videos` `wanx2.1-i2v-plus` [`wanx2.1-i2v-plus`](https://ailoot.ai/models/en/#m=wanx2.1-i2v-plus&route=Ultra&caller=wanx2.1-i2v-plus&fmt=videos) Other /`wanx2.1-i2v-plus` ### Overview Wanx 2.1 I2V Plus creates a video from supplied image material and a motion prompt.

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.
