Input Parameters
| Name | Type | Description | Default | Constraints |
|---|---|---|---|---|
image * | string (uri) | Image for use as the initial frame of the video. | — | — |
prompt * | string | Text prompt for image generation | — | — |
aspect_ratio | string | Aspect ratio of the output video. | "16:9" | 16:9 9:16 |
disable_safety_checker | boolean | Disable safety checker for generated videos | false | — |
fast_mode | string | Speed up generation with different levels of acceleration. Faster modes may degrade quality somewhat. The speedup is dependent on the content, so different videos may see different speedups. | "Balanced" | Off Balanced Fast |
lora_scale | number | Determines how strongly the main LoRA should be applied. Sane results between 0 and 1 for base inference. You may still need to experiment to find the best value for your particular lora. | 1 | min: 0, max: 4 |
lora_weights | string | Load LoRA weights. Supports HuggingFace URLs in the format huggingface.co/<owner>/<model-name>, CivitAI URLs in the format civitai.com/models/<id>[/<model-name>], or arbitrary .safetensors URLs from the Internet. | — | — |
negative_prompt | string | Negative prompt to avoid certain elements | "" | — |
sample_guide_scale | number | Guidance scale for generation | 5 | min: 1, max: 10 |
sample_shift | integer | Flow shift parameter for video generation | 3 | min: 0, max: 10 |
sample_steps | integer | Number of inference steps | 30 | min: 1, max: 40 |
seed | integer | Random seed. Set for reproducible generation | — | — |
