About

Accelerated inference for Wan 2.1 14B text to video, a comprehensive and open suite of video foundation models that pushes the boundaries of video generation.

Example Output

Prompt:

"A cat is doing an acrobatic dive into a swimming pool at the olympics, from a 10m high diving board, flips and spins"

{
  "prompt": "A cat is doing an acrobatic dive into a swimming pool at the olympics, from a 10m high diving board, flips and spins",
  "fast_mode": "Balanced",
  "num_frames": 81,
  "aspect_ratio": "16:9",
  "sample_shift": 5,
  "sample_steps": 30,
  "frames_per_second": 16,
  "sample_guide_scale": 5
}
Input Parameters
seed Type: integer
Random seed. Set for reproducible generation
prompt (required) Type: string
Text prompt for image generation
fast_mode Default: Balanced
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.
lora_scale Type: numberDefault: 1Range: 0 - 4
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.
aspect_ratio Default: 16:9
Aspect ratio of the output video.
lora_weights Type: 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.
sample_shift Type: integerDefault: 3Range: 0 - 10
Flow shift parameter for video generation
sample_steps Type: integerDefault: 30Range: 1 - 40
Number of inference steps
negative_prompt Type: stringDefault:
Negative prompt to avoid certain elements
sample_guide_scale Type: numberDefault: 5Range: 1 - 10
Guidance scale for generation
disable_safety_checker Type: booleanDefault: false
Disable safety checker for generated videos
