Wan 2.7 — Reference to Video


Model ID	`alibaba/wan-2-7-r2v`
Family	`wan-2-7-novita`
Task	`reference-to-video`
Modality	Video
Upstream	Alibaba Wan 2.7

Like T2V, the output dimension is the explicit size field (full pixel dimensions) — it sets both the aspect ratio and the price tier. At least one of image_urls or video_urls should be supplied — the whole point of this task is to bias generation on references.

Endpoint

POST https://routerbase.com/v1/videos/generations

Async — returns {id, status: "pending"}; poll GET /v1/videos/generations/{id} until success or failed.

enum

default:"\"1920*1080\""

Full pixel dimensions — sets the aspect ratio and the price tier. One of 1920*1080, 1080*1920, 1440*1440, 1632*1248, 1248*1632 (~2M px, $0.15/s**), or `1280*720`, `720*1280`, `960*960`, `1088*832`, `832*1088` (~0.9M px, **$ 0.10/s).

integer

default:"5"

Length of the generated clip in seconds. Range [2, 10].

"single" | "multi"
