Create Jaw-Dropping Object-Splitting Videos with This Specialized Workflow
1. Workflow Overview

This is a Wan2.1-based video generation workflow specialized in creating object-splitting visual effects (e.g., explosions, fragmentation). Key features:
Generates dynamic videos from a single image + text prompt
Supports LoRA fine-tuning (e.g., "Division" or "Bloom" effects)
Optional post-processing: upscaling + frame interpolation (FILM VFI)
2. Core Models
Model | Function | Source |
---|---|---|
Wan2.1-I2V-14B | Base image-to-video model | Manual download required |
umt5-xxl-enc | Multilingual text encoder | Built-in |
Wan2.1-Division-LoRA | Controls splitting effects style | Separate download |
3. Key Nodes
Node | Purpose | Installation |
---|---|---|
| Loads main video model | Via |
| Selects effect LoRAs | Built-in |
| Frame interpolation | Requires |
| Video rendering | Requires |
4. Workflow Structure
Group 1: Video Generation
Inputs: Image + prompt (e.g., "object shattering into pieces")
Output: 480P raw video
Key Params: Frames (default 81), resolution (768xauto)
Group 2: Post-Processing
Functions: 4x upscale + 10x frame interpolation
Warning: Reduce original frames/resolution to avoid OOM
5. Inputs & Outputs
Input Parameters:
positive_prompt
: Describes splitting effect (e.g., "woman spinning and exploding")num_frames
: Total frames (recommend ≤81)generation_width
: Video width (recommend ≤768px)
Output:
MP4 video (H.264, 16FPS by default)
6. Notes
VRAM: Minimum 12GB GPU (for 480P generation)
Common Errors:
module 'comfy.model_management'
→ Insufficient VRAM, reduce framesInterpolation failure → Disable
