Embedding Amplifier Guide

The Problem It Solves

When using FP8 quantization, even "different" prompts often produce embeddings that are only 10-30% different. This is too similar for visible injection effects. The Embedding Amplifier ensures your injection embeddings are different enough to work.

How to Use It

Connect Your Embeddings
- Main prompt → main_embeds input
- Injection prompt → injection_embeds input
Set Target Difference
- Default: 60% (good for most cases)
- Range: 30-90%
- Higher = more dramatic effects
Choose Amplification Mode
- push_apart: Gentle amplification, preserves structure (default)
- maximize_diff: Aggressive, focuses on high-variance dimensions
- orthogonalize: Mathematical approach, makes embeddings perpendicular
Use Amplified Output
- Connect amplified_injection to WanVideoActivationEditor's injection input

Example Workflow

Main Prompt: "A sunny beach with people"
Injection Prompt: "A rainy beach with people"
Original Difference: 22%  ← Too similar!

→ Amplifier (60% target) →

Amplified Difference: 60%  ← Now it works!

Tips

Start with push_apart mode - it's the safest
If effects are still subtle, try 70-80% target
Use maximize_diff for more dramatic changes
orthogonalize is best for style transfer

When NOT to Use It

If your prompts already differ by >50%, you don't need it
If you want subtle effects, keep target low (30-40%)
Don't use with completely unrelated prompts (they're already different enough)
