: FP16 (Half-precision floating point), resulting in a file size of approximately Resolution : Optimized for (720p) generation. Primary Nodes : Typically used with the WanImageToVideo Hardware Requirements

The wan2.1_i2v_720p_14b_fp16.safetensors checkpoint is highly versatile and fits into several popular UI ecosystems. 1. ComfyUI Deployment

import torch from diffusers import WanVideoPipeline # Note: Ensure you use the I2V specific loading parameters # This requires installing 'diffusers' and 'transformers' from source or late versions pipe = WanVideoPipeline.from_pretrained( "Wan-Video/Wan2.1-I2V-720P-14B", torch_dtype=torch.float16 ) pipe.to("cuda") # Add your conditioning image and text prompt here image = load_your_image("input.png") prompt = "A gentle breeze blowing through her hair, highly detailed, 4k resolution." video_frames = pipe(prompt, image=image, num_frames=81, height=720, width=1280).frames # Export frames to MP4 Use code with caution. Tips for Getting the Best Results

# Load your source anchor image init_image = load_image("path_to_your_input_image.png") # Define prompt directing the motion prompt = "Cinematic slow motion, waves crashing against the rocks, detailed water droplets, dramatic lighting, 8k resolution" negative_prompt = "static, low quality, distorted anatomy, fast cuts, text, watermark" # Generate video frames video_frames = pipeline( prompt=prompt, negative_prompt=negative_prompt, image=init_image, num_frames=81, # Standard length for Wan2.1 video clips height=720, width=1280, guidance_scale=6.0, num_inference_steps=50, generator=torch.manual_seed(42) ).frames Use code with caution.

: Image-to-Video. This model takes a static source image and a text prompt to generate fluid, realistic video sequences. wan2.1 i2v 720p 14b fp16.safetensors

wan2.1_i2v_720p_14B_fp16.safetensors is the definitive file for users who demand the absolute best quality from their AI-generated videos on consumer hardware—provided they have the hardware to match. It represents the pinnacle of the Wan2.1 lineup, delivering state-of-the-art 720p video from a static image. While its immense VRAM requirements and slow generation times are significant barriers, its existence pushes the entire field forward. For those with an NVIDIA RTX 4090 or equivalent high-VRAM GPU, and the patience to wait for top-tier results, this model is the gold standard. For all others, the community-optimized fp8 versions offer a far more accessible and practical entry point into the same powerful technology.

The FP16 safetensors file is approximately 28 GB. This makes it just loadable on a single 32GB VRAM GPU (like an A100 40GB, RTX 6000 Ada, or two 24GB consumer cards via model sharding).

: Ensure the output resolution is set to 1280x720 (720p), as this model is specifically trained for that aspect ratio.

The Wan2.1 suite isn't just a single model; it's a highly advanced system. The i2v_720p_14b_fp16 is the largest core diffusion model within this system. Its architecture incorporates several cutting-edge features: : FP16 (Half-precision floating point), resulting in a
