Request body
16 properties · 3 required · 1 $defs| property | type | description | constraints |
|---|---|---|---|
| end_image_url* | string | URL of the ending image. If the input image does not match the chosen aspect ratio, it is resized and center cropped. | |
| start_image_url* | string | URL of the starting image. If the input image does not match the chosen aspect ratio, it is resized and center cropped. | |
| prompt* | string | The text prompt to guide video generation. | |
| enable_prompt_expansion | boolean | Whether to enable prompt expansion. | default: false |
| shift | number | Shift parameter for video generation. | 1 ≤ n ≤ 10 · default: 5 |
| num_inference_steps | integer | Number of inference steps for sampling. Higher values give better quality but take longer. | 2 ≤ n ≤ 40 · default: 30 |
| negative_prompt | string | Negative prompt for video generation. | default: "bright colors, overexposed, sta… |
| loras | LoraWeight[] | LoRA weights to be used in the inference. | default: [] |
| guide_scale | number | Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality. | 1 ≤ n ≤ 10 · default: 5 |
| aspect_ratio | enum | Aspect ratio of the generated video. If 'auto', the aspect ratio will be determined automatically based on the input image. | auto | 16:9 | 9:16 | 1:1 · default: "auto" |
| frames_per_second | integer | Frames per second of the generated video. Must be between 5 to 24. | 5 ≤ n ≤ 24 · nullable |
| resolution | enum | Resolution of the generated video (480p or 720p). 480p is 0.5 billing units, and 720p is 1 billing unit. | 480p | 720p · default: "720p" |
| acceleration | enum | Acceleration level to use. The more acceleration, the faster the generation, but with lower quality. The recommended value is 'regular'. | none | regular · default: "regular" |
| seed | integer | Random seed for reproducibility. If None, a random seed is chosen. | nullable |
| enable_safety_checker | boolean | If set to true, the safety checker will be enabled. Disabling it requires account authorization; unauthorized requests are always checked. | default: false |
| num_frames | integer | Number of frames to generate. Must be between 81 to 100 (inclusive). If the number of frames is greater than 81, the video will be generated with 1.25x more billing units. | 81 ≤ n ≤ 100 · nullable |
Types
1 $defsLoraWeightobject
| path* | string | URL or the path to the LoRA weights. | |
| scale | number | The scale of the LoRA weight. This is used to scale the LoRA weight before merging it with the base model. | 0 ≤ n ≤ 4 · default: 1 |
| weight_name | string | Name of the LoRA weight. Used only if `path` is a Hugging Face repository, and required only if you have more than 1 safetensors file in the repo. | nullable |
