Describes the resource file to be used by the model for video generation, divided into first and last frame mode, reference image/video/sound generation, video editing, and other modes.

First and last frame video generation: The Usage field of the first frame image is FirstFrame, and the Usage field of the last frame image is LastFrame. One image is supported for each. The first frame can be imported separately, but the last frame cannot be imported separately. First and last frame generation uses the image ratio for reference.
Reference image/video/sound generation: You can import single or multiple images/videos/sounds as references, with the Usage field set to Reference. In reference mode, you can adjust the aspect ratio of the generated video.
Video editing: Vidu and Kling can input a video for editing. You can also import images while importing a video, with the Usage field of the image set to Reference.

Note:

1. Image size cannot exceed 10 MB.
2. Supported image formats: jpeg, jpg, png. x0b
3. For whether a specific model version supports reference image/video/sound, first and last frame, video editing, and other features, you can request documentation from us or refer to the original vendor's document information.

2. Image size must be less than 5M.
3. Supported image formats: jpeg, jpg, png, webp.

Prompt for video generation.
When no reference file is passed in, no usage scenario type is used, and ExtInfo is not null, Prompt is required.

Prompt to prevent the model from generating videos.

Whether to optimize Prompt content automatically. When Enabled, the passed-in Prompt will be optimized automatically to enhance generation quality. Valid values:

Output media file configuration for a video task.
