Wan 2.7

Generate videos from text or images with the Alibaba Wan 2.7 model — first-and-last-frame, video continuation, automatic audio, up to 1080p.

POST /v2/videos/generate — model: "wan-2.7"

Combined text-to-video and image-to-video generation at 720p or 1080p, 2–15 seconds. Supports first-and-last-frame (FLF) constraints, continuation from an existing video clip, custom driving audio, and automatic prompt expansion. When no audio is provided the model auto-generates a matching soundtrack.

The mode is selected automatically:

Provide neither image nor first_clip → text-to-video.
Provide image → image-to-video (optionally with last_frame for FLF).
Provide first_clip → continuation from the given video (optionally with last_frame).

image and first_clip are mutually exclusive.

See Video Generation overview for common request fields, response format, and error codes.

Model-specific parameters

Parameter	Type	Required	Default	Description
`wan27Params.image`	string	No	—	First-frame image URL for I2V. Mutually exclusive with `first_clip`.
`wan27Params.last_frame`	string	No	—	Optional last-frame image URL. Requires `image` (FLF) or `first_clip` (continuation with target last frame).
`wan27Params.first_clip`	string	No	—	Source clip (2–10 s) to continue from. Mutually exclusive with `image`.
`wan27Params.audio`	string	No	—	Driving audio URL (wav/mp3, 3–30 s, ≤ 15 MB). Omit to auto-generate.
`wan27Params.resolution`	string	No	`"1080p"`	Output resolution: `"720p"` or `"1080p"`.
`wan27Params.aspect_ratio`	string	No	—	T2V only. One of `"16:9"`, `"9:16"`, `"1:1"`, `"4:3"`, `"3:4"`. I2V inherits aspect ratio from the input.
`wan27Params.duration`	number	No	`5`	Video duration in seconds (integer, 2–15).
`wan27Params.negative_prompt`	string	No	—	Elements to avoid in the generated video.
`wan27Params.enable_prompt_expansion`	boolean	No	—	Enable automatic prompt optimization.
`wan27Params.seed`	number	No	—	Random seed for reproducible generation.

Credit cost

Pricing is per second of generated video (credits = rate × duration).

Mode	Resolution	Credits / second
T2V	720p	17
T2V	1080p	17
I2V (image or first_clip)	720p	17
I2V (image or first_clip)	1080p	26

A 10-second I2V clip at 1080p therefore costs 26 × 10 = 260 credits.
