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:
low quality, blurry, watermark, text, logo, glitch, jpeg artifacts, deformed, distorted face, extra fingers, bad hands
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:
face morphing, facial distortion, warped face, deformed face
If motion looks jittery or “strobe-y”
Add:
jerky motion, jitter, stuttering, flicker
If the clip keeps going static
This is often a positive prompt issue (you didn’t describe motion), but you can also try:
still image, frozen, static
If it adds unwanted text/watermarks
Add:
watermark, text, signature, logo
The Rule: Negative Prompts Can’t Replace Good Prompts
If your positive prompt is:
a person in a room
…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
- Generate a draft without negatives
- Identify the one artifact that ruins it (blur? face morph? text?)
- Add only the tags that target that artifact
- Re-run once
- Stop adding tags when the artifact is gone
This is faster than dumping a generic 200-tag list into every generation.
