1. Workflow Overview

Purpose:
Named "Crystal Cutting", this workflow generates dynamic videos of transparent crystal objects being cut. Key features:Static Image Generation: Creates high-transparency crystal objects (e.g., watermelon, cherry) via Stable Diffusion.
Video Animation: Uses WanVideo nodes to animate cutting actions (e.g., knife slicing crystal watermelon).
Style Control: LoRAs (e.g.,
Glass&Crystal Fruits-F1_V1) enhance material realism.
2. Key Components
Critical Nodes:
WanVideoModelLoader:Loads video model (
Wan2_1-I2V-14B-480P_fp8_e4m3fn.safetensors).Plugin:
ComfyUI-WanVideoWrapper.
WanVideoTextEncode:Inputs cutting prompts (e.g., "A knife cutting a transparent crystal watermelon").
Negative prompts avoid artifacts (e.g., "blurry, low quality").
WanVideoImageClipEncode:Encodes static images into video latent frames (resolution
832x832, 49 frames).
WanVideoSampler:Sampler:
unipc, 6 steps.
VHS_VideoCombine:Outputs MP4 video (16fps, CRF=19).
Dependencies:
LoRA Models:
CakeCutting(WanVideo2.1 I2V LoRA)_V1: Must be placed inmodels/loras/.
Plugins:
ComfyUI-VideoHelperSuite: For video synthesis.ComfyUI-WanVideoWrapper: Install manually via GitHub.

4. Inputs & Outputs
Inputs:
Image: Static crystal object (e.g.,
jimeng-2025-06-19-5212.png).Text: Bilingual prompts (e.g., "Transparent crystal watermelon + cutting action").
Params: Resolution
832x832, FPS16.
Output:
MP4 video (e.g.,
WanVideo2_1_T2V.mp4).
5. Tips & Warnings
VRAM: ≥12GB GPU recommended for video generation.
Paths: Verify LoRA/model file paths.
Frame Limit: High frames (e.g., 49) may slow generation; test with 24 frames first.
