Input Schema

​
prompt
string
required
The text prompt used to generate the video.
​
image_urls
list<string>
Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPEG, PNG, WebP. Max 30 MB per image. Up to 9 images. Total files across all modalities must not exceed 12.
​
video_urls
list<string>
Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 3 videos, combined duration must be between 2 and 15 seconds, total size under 50 MB. Each video must be between ~480p (640x640) and ~720p (834x1112) in resolution.
​
audio_urls
list<string>
Reference audio to guide video generation. Refer to them in the prompt as @Audio1, @Audio2, etc. Supported formats: MP3, WAV. Up to 3 files, combined duration must not exceed 15 seconds. Max 15 MB per file.If audio is provided, at least one reference image or video is required.
​
resolution
ResolutionEnum
default:"720p"
Video resolution - 480p for faster generation, 720p for balance. Default value: "720p"Possible values: 480p, 720p
​
duration
DurationEnum
default:"auto"
Duration of the video in seconds. Supports 4 to 15 seconds, or auto to let the model decide based on the prompt. Default value: "auto"Possible values: auto, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15
​
aspect_ratio
AspectRatioEnum
default:"auto"
The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. Default value: "auto"Possible values: auto, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16
​
generate_audio
boolean
default:"true"
Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not. Default value: true
​
seed
integer
Random seed for reproducibility. Note that results may still vary slightly even with the same seed.
​
end_user_id
string
The unique user ID of the end user.

​
Output Schema

​
video
File
