Input Parameters
| Name | Type | Description | Default | Constraints |
|---|---|---|---|---|
prompt * | string | Text prompt for video generation | — | — |
aspect_ratio | string | The aspect ratio of the video. 16:9, 9:16, 1:1, etc. | "16:9" | 16:9 9:16 1:1 |
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 |
frames | integer | The number of frames to generate (1 to 5 seconds) | 81 | 17 33 49 65 81 |
image | string (uri) | Image to use as a starting frame for image to video generation. | — | — |
lora_strength_clip | number | Strength of the LORA applied to the CLIP model. 0.0 is no LORA. | 1 | — |
lora_strength_model | number | Strength of the LORA applied to the model. 0.0 is no LORA. | 1 | — |
lora_url | string | Optional: The URL of a LORA to use | — | — |
model | string | The model to use. 1.3b is faster, but 14b is better quality. A LORA either works with 1.3b or 14b, depending on the version it was trained on. | "14b" | 1.3b 14b |
negative_prompt | string | Things you do not want to see in your video | "" | — |
resolution | string | The resolution of the video. 720p is not supported for 1.3b. | "480p" | 480p 720p |
sample_guide_scale | number | Higher guide scale makes prompt adherence better, but can reduce variation | 5 | min: 0, max: 10 |
sample_shift | number | Sample shift factor | 8 | min: 0, max: 10 |
sample_steps | integer | Number of generation steps. Fewer steps means faster generation, at the expensive of output quality. 30 steps is sufficient for most prompts | 30 | min: 1, max: 60 |
seed | integer | Set a seed for reproducibility. Random by default. | — | — |
