ComfyUI-QwenImageWanBridge

Custom nodes for bridging Qwen-Image and WAN video models in ComfyUI.

Nodes

Diagnostic Nodes

VAE Diagnostic

Analyzes compatibility between Qwen and WAN VAEs

• Compares latent encodings
• Shows statistical differences
• Recommends best practices

Simple VAE Test

Quick recommendations for different workflows

• Qwen to WAN
• WAN to Qwen
• Best practices

Bridge Nodes

Qwen-WAN Bridge

Bridges latents between models

• Handles dimension differences
• Fixes temporal structure
• Uses WAN VAE (always!)

Always Use WAN VAE

Enforces the golden rule - WAN VAE for everything

• Decodes with WAN VAE
• Works with both model types
• No bizarre frames!

Latent Mixer

Mix latents from different models

• Linear or spherical interpolation
• Style mixing
• Cross-model blending

Example Workflows

Basic Cross-Model Workflow

[Qwen Model] → [KSampler] → [Always Use WAN VAE] → [Image]
                                    ↑
                              [Load WAN VAE]

Diagnostic Workflow

[Load Image] → [VAE Diagnostic] → [View Report]
                ↑            ↑
          [Qwen VAE]    [WAN VAE]

Style Mixing Workflow

[Qwen Generate] → [Latent Mixer] → [Always Use WAN VAE] → [Image]
[WAN Generate] ↗                            ↑
                                       [Load WAN VAE]
