AI video generation just leveled up. With Alibaba’s new Wan 2.1 Fun Control model, you can now produce professional-quality videos with consistent styles and smooth motion—right from ComfyUI. I’ve tested this extensively, and in this guide, I’ll show you exactly how it works, with actionable steps to get the best results.
Why Wan 2.1 Fun Control Stands Out
Most AI video tools struggle with flickering or inconsistent details between frames. Wan 2.1 solves this by:
- Keeping styles coherent—characters and backgrounds stay uniform, even with camera moves
- Precise motion control—using ControlNet (pose, depth, or line art) to guide movements
- Efficient rendering—batches multiple frames at once for faster processing
It’s ideal for music videos, social media ads, or game animations where quality matters.
What You’ll Need
- ComfyUI (updated to the latest version)
- Wan 2.1 Fun Control model (download from Hugging Face)
- A reference video (5–10 seconds works best for testing)
- A decent GPU (8GB VRAM minimum for 480p output)
Place it in:
ComfyUI/models/diffusion/ - Rename it clearly (e.g.,
Wan_2.1_Fun_Control_1.3B.safetensors).
Tip: If you’re new to ComfyUI, install the Manager plugin first to handle dependencies.
Step 2: Build the Workflow
Here’s the key setup I use (you can copy this structure):
1. Input Video Prep
- Use the Load Video node to import your clip.
- Set dimensions to 832×480 (Wan 2.1’s optimal resolution).
- Extract the first frame with Get Image from Batch—this will be your style reference.
2. Style Customization
- Run the first frame through Flux Turbo + a LoRA (e.g., for an anime look).
- Keep the pose intact but transform colors/textures.
3. ControlNet Setup
- Preprocess the video with:
- DW Pose for body movements
- Line Art for clothing/details (optional)
- Adjust weights (start with 1.0 for pose, 0.7 for line art).
4. Generate the Video
- Connect everything to the Wan Fun Control to Video node.
- Settings I recommend:
- CFG Scale: 7–9
- Sampler: Euler a or DPM++ 2M
- Frames per Batch: 8 (for 8GB VRAM)
Final Thoughts
Wan 2.1 Fun Control is a game-changer for AI video. It’s not perfect—long clips still need segmentation—but for short, high-quality animations, it’s my go-to tool now.
