Wan 2.7 Negative Prompts: A Starter List to Reduce Artifacts

Negative prompts are not magic. They are a steering wheel.

Used well, they reduce the junk that ruins otherwise good clips:

• blur
• watermarks/text artifacts
• face morphing
• glitchy motion

Used badly, they just add noise.

This is a starter list you can copy, then tighten based on what you see.

The Short “Default” Negative Prompt (Start Here)

Try this first:

Keep it short. If you add 80 tags, you won’t know what fixed the problem.

Targeted Negative Prompts (Use Only When Needed)

If faces morph or melt

Add:

If motion looks jittery or “strobe-y”

Add:

If the clip keeps going static

This is often a positive prompt issue (you didn’t describe motion), but you can also try:

If it adds unwanted text/watermarks

Add:

The Rule: Negative Prompts Can’t Replace Good Prompts

If your positive prompt is:

…no negative prompt list will create a cinematic shot with intentional motion. You need to specify:

• what moves
• how fast it moves
• what the camera does

That’s why your best “quality hack” is usually rewriting the main prompt.

A Simple Workflow That Works

1. Generate a draft without negatives
2. Identify the one artifact that ruins it (blur? face morph? text?)
3. Add only the tags that target that artifact
4. Re-run once
5. Stop adding tags when the artifact is gone

This is faster than dumping a generic 200-tag list into every generation.
