Wan 2.2 14B i2v & t2v Enhanced Motion + 5B Latent Upscaler - Ultimate 6 Steps HD Pipeline

The ONLY workflow you need.

Fixes slow motion, boosts detail with Pusa LoRAs, and features a revolutionary 2-stage upscaler with WanNAG for breathtaking HD videos.

Just load your image and go!

🚀 The Ultimate Wan2.2 Workflow is HERE! Tired of these problems?

Slow, sluggish motion from your Wan2.2 generations?
Low-quality, blurry results when you try to generate faster?
VRAM errors when trying to upscale to HD?
Complex, messy workflows that are hard to manage?

This all-in-one solution fixes it ALL. We've cracked the code on high-speed, high-motion, high-detail generation.

This isn't just another workflow; it's a complete, optimized production pipeline that takes you from a single image to a stunning, smooth, high-definition video with unparalleled ease and efficiency. Everything is automated and packaged in a clean, intuitive interface using subgraphs for a clutter-free experience.

✨ Revolutionary Features & "Magic Sauce" Ingredients:

1. 🎯 AUTOMATED & USER-FRIENDLY

Fully Automatic Scaling: Just plug in your image! The workflow intelligently analyzes and scales it to the perfect resolution (~0.23 Megapixels) for the Wan 14B model, ensuring optimal stability and quality without any manual input.
Clean, Subgraph Architecture: The complex tech is hidden away in organized, collapsible groups ("Settings", "Prompts", "Upscaler"). What you see is a simple, linear flow: Image -> Prompts -> SD Output -> HD Output. It’s powerful, but not complicated.

2. ⚡ ENHANCED MOTION ENGINE (The 14B Core)

This is the heart of the solution. We solve the slow-motion problem with a sophisticated dual-sampler system:

Dual Model Power: Uses both the Wan2.2-I2V-A14B-HighNoise and -LowNoise models in tandem.
Pusa LoRA Quality Anchor: The breakthrough! We inject Pusa V1 LoRAs (HIGH_resized @ 1.5, LOW_resized @ 1.4) into both models. This allows us to run at an incredibly low 6 steps while preserving the sharp details, contrast, and texture of a high-step generation. No more quality loss for speed!
Lightx2v Motion Catalyst: To supercharge motion at low steps, we apply the powerful lightx2v 14B LoRA at different strengths: a massive 5.6 strength on the High-Noise model to establish strong, coherent motion, and a refined 2.0 strength on the Low-Noise model to clean it up. Result: Dynamic motion without the slowness.

3. 🎨 LOW-RAM HD UPsCALING CHAIN (The 5B Power-Up)

This is where your video becomes a masterpiece. A genius 2-stage process that is shockingly light on VRAM:

Stage 1 - RealESRGAN x2: The initial video is first upscaled 2x for a solid foundation.
Stage 2 - Latent Detail Injection: This is the secret weapon. The upscaled frames are refined in the latent space by the Wan2.2-TI2V-5B model.
- FastWan LoRA: We use the FastWanFullAttn LoRA to make the 5B model efficient, requiring only 6 steps at a denoise of 0.2.
- WanVideoNAG Node: Critically, this stage uses the WanVideoNAG (Nested Adaptive Gradient) technique. This allows us to use a very low CFG (1.0) for natural, non-burned images while maintaining the power of your negative prompt to eliminate artifacts and guide the upscale. It’s the best of both worlds.
Result: You get the incredible detail and coherence of a 5B model pass without the typical massive VRAM cost.

4. 🍿 CINEMATIC FINISHING TOUCHES

RIFE Frame Interpolation: The final step. The upscaled video is interpolated to a silky-smooth 32 FPS, eliminating any minor stutter and delivering a professional, cinematic motion quality.
