Wan 2.7 I2V - MixRoute API

Wan 2.7 I2V supports first-frame and first/last-frame generation, driving audio, and continuation from a first_clip video. Use the exact model ID wan2.7-i2v with the MixRoute Video Generations API.

Model Specifications

Property	Value
Mode	Image-to-Video
Resolution	720P / 1080P
Duration (seconds)	2-15
Output	MP4 / 30 fps
Request	`model` + `metadata.input` + `metadata.parameters`

The Wan API reference defines the model-specific fields, media limits, defaults, and polling workflow. Do not copy a different version’s input or output-size fields.

Set MIXROUTE_API_KEY and replace media placeholders with accessible files.
