🎞️ ComfyUI Image-to-Video Workflow - WAN 2.1 Wrapper (Kiko WAN v3)
This is a high-performance, multi-pass Image-to-Video workflow for ComfyUI, powered by the WAN 2.1 Wrapper, with advanced optimizations like `torch.compile` and Sage Attention for faster and smarter frame generation. I tried to expose all the settings that Kijai exposes that I can understand 😉, This is not the fastest workflow you will find on here, but it is one I use to make 20 secons videos.
Crafted with ❤️ on Arch Linux BTW, using an RTX 4090 and 128 GB of RAM—this setup is tuned for heavy-duty inference and silky-smooth video generation.

🛠️ Workflow Overview
🔹 Input & Resize
- Drop an image and optionally resize to fit WAN 2.1's expected input.
🔹 WAN 2.1 Wrapper Core
- Uses `torch.compile` for speed boost
- Enhanced with Sage Attention (set via the custom node or environment)
🔹 Pass 1: Generate + Optional Slow Motion
- Frame-by-frame synthesis
- Add slow motion via interpolation node (RIFE or FILM)
🔹 Pass 2: Extend + Merge
- Extends the motion, ensures smoother transitions
- Combines motion with refined prompt guidance
🔹 Final Polish
- Sharpening and Upscaling
- Final interpolation if needed
- Loop-ready output by extending the last frame

🧪 Performance Tips
- Tune torch compile for you system, they are all different, my setting might not work for you.
- For Sage Attention:
- Use the node
- Running on lower-end GPUs? Disable upscaling and reduce frame count.

🧰 Requirements
- ComfyUI
- WAN 2.1 Wrapper Node
- Optional:
- `RIFE`, `FILM`, or `DAIN` for interpolation
- `RealESRGAN` / `SwinIR` for upscaling
- `Sage Attention` patch or node

▶️ How to Use
1. Load the `kiko-wan-v3.json` file into ComfyUI.
2. Drop your image into the input node.
3. Customize prompts, duration, and frame count.
4. Click `Queue Prompt` to generate.
5. Your video will be rendered in the output folder.
