Wan 2.2 + Lightx2v V2 | Ultra Fast I2V & T2V

What is the Wan 2.2 + Lightx2v V2 ComfyUI Workflow?

The Wan 2.2 + Lightx2v V2 ComfyUI workflow represents a breakthrough in ultra-fast text-to-video and image-to-video generation, combining Alibaba's powerful Wan 2.2 14B model with the revolutionary Lightx2v V2 LoRA distillation technology. This workflow delivers professional-quality video generation at lightning speed - up to 4x faster than standard Wan 2.2 workflows while maintaining excellent visual quality.

Wan 2.2 + Lightx2v V2 uses a two-stage sampling process: a high-noise model that establishes the basic video structure, followed by a low-noise model that adds fine details and refinements. The Lightx2v V2 component is a specialized distillation LoRA that compresses this Wan 2.2 process dramatically - reducing the standard 40 steps (20+20) to just 8-14 steps while using low CFG settings and LCM sampling for maximum speed.

Think of Wan 2.2 + Lightx2v V2 as having a turbocharged video generator that maintains the quality of the original two-stage Wan 2.2 process but cuts generation time by up to 75%. Perfect for rapid prototyping, content creation, and professional video workflows where speed matters.

Key Features and Benefits of Wan 2.2 + Lightx2v V2

Ultra-Fast Generation with Flexible Steps: The Wan 2.2 + Lightx2v V2 workflow reduces standard 40-step sampling to just 8-14 steps using distillation techniques. Choose 8 steps (maximum speed), 12 steps (balanced), or 14 steps (optimal quality) in your Wan 2.2 + Lightx2v V2 setup.

Advanced LoRA Acceleration Options: Offers full acceleration (both stages) for maximum speed or half-acceleration (refinement only) for better prompt control while maintaining significant performance gains.

Optimized for Lower Hardware Requirements: The Wan 2.2 + Lightx2v V2 combination reduces VRAM usage and computational cost through LCM sampling with low CFG settings, making high-quality video generation more accessible.

Professional Quality Output: Maintains the high-quality video generation and motion coherence of the original Wan 2.2 despite the dramatic speed improvements through advanced Lightx2v V2 distillation technology.

How to Use Wan 2.2 + Lightx2v V2 in ComfyUI

Text-to-Video Generation Workflow

Configure your Wan 2.2 + Lightx2v V2 video parameters

• Use the EmptyHunyuanLatentVideo node to set your video dimensions:
  • Width: 704 pixels (optimized for Wan 2.2 + Lightx2v V2)
  • Height: 544 pixels
  • Length: 81 frames for ~3.4 second videos at 24fps
  • Batch_size: Keep at 1 for optimal Wan 2.2 + Lightx2v V2 performance

Craft your text prompt for Wan 2.2 + Lightx2v V2

• In the CLIP Text Encode (Positive Prompt) node:
  • Write detailed, descriptive prompts for best results
  • Include motion descriptions and camera movements
  • Specify lighting, mood, and visual style preferences for your Wan 2.2 + Lightx2v V2 generation

Essential Wan 2.2 + Lightx2v V2 KSampler Settings (Flexible Configuration)

• High Noise KSampler (Wan 2.2 Foundation Stage):
  • Steps: 4-7 (adjust based on Wan 2.2 + Lightx2v V2 speed vs quality needs)
  • CFG: 1.0-3.5 (lower for speed, higher for prompt control in Wan 2.2 + Lightx2v V2)
  • Sampler: lcm (for Lightx2v V2 acceleration) or euler (for quality retention)
  • Scheduler: simple
• Low Noise KSampler (Wan 2.2 + Lightx2v V2 Refinement Stage):
  • Steps: 8-14 total (adjust based on desired Wan 2.2 + Lightx2v V2 quality level)
  • CFG: 1.0-3.5 (coordinate with foundation stage settings)
  • Sampler: lcm (recommended for Lightx2v V2 refinement acceleration)
  • Scheduler: simple
  • Important: Set the High Noise KSampler's end_at_step and Low Noise KSampler's start_at_step to half your total steps (e.g., both set to 4 for 8 total steps, or 6 for 12 total steps) to ensure proper Wan 2.2 + Lightx2v V2 stage handoff.

Wan 2.2 + Lightx2v V2 Parameter Guidelines

• Total Steps: 8-14 steps work well for Wan 2.2 + Lightx2v V2 - adjust based on your speed vs quality priorities
• CFG Values: 1.0-3.5 range for Wan 2.2 + Lightx2v V2 - lower values for faster generation, higher for better prompt following
• Mix and Match: Combine different Wan 2.2 + Lightx2v V2 settings to find your optimal balance

Universal LoRA Acceleration Settings (Both T2V and I2V)

Wan 2.2 + Lightx2v V2 LoRA Configuration Options

• LoraLoaderModelOnly nodes control the Wan 2.2 + Lightx2v V2 acceleration level:
  • T2V LoRA: lightx2v_T2V_14B_cfg_step_distill_v2_lora_rank64_bf16.safetensors
  • I2V LoRA: lightx2v_I2V_14B_480p_cfg_step_distill_rank128_bf16.safetensors
  • Full Acceleration: Apply Lightx2v V2 LoRA to both high-noise (foundation) and low-noise (refinement) models with strength 1.0
  
  • Half Acceleration: Apply Lightx2v V2 LoRA only to the low-noise (refinement) model with strength 1.0 - better prompt control for Wan 2.2 + Lightx2v V2
  

Wan 2.2 + Lightx2v V2 Speed vs Quality Comparison
