The standard set for series work is five exclusions: no face swaps, no wardrobe changes, no broken hands, no floating props, no camera jumps. Write it once, append it unchanged to every prompt. The discipline isn't picking the right words — it's resisting the urge to edit them on shot four, because a negative set that varies introduces exactly the inconsistency it exists to prevent.
Most guides give negative prompts a sentence. The interesting question isn't what to put in them, it's why the answer stops working the moment you start tinkering.
What the standard set is
Five exclusions, each catching a specific failure that recurs in series work.
no face swaps, no wardrobe changes, no broken hands, no floating props, no camera jumps
Append unchanged to every prompt in a series. Copy it — don't retype it.
What each one catches
Worth knowing, because the list looks arbitrary until you've hit all five.
- No face swaps
- The character arriving with a different face. The most damaging failure in serial work, because a viewer who notices it stops following the story to check whether it's the same person.
- No wardrobe changes
- Clothing shifting between shots in the same scene. Less dramatic than a face change and often more noticeable, because wardrobe is what viewers use to track who's who at phone size.
- No broken hands
- The oldest generative failure and still the one people screenshot. Hands are also unavoidable in dialogue scenes, where they're gesturing near the face the viewer is already looking at.
- No floating props
- Objects losing their physical relationship to a surface or a hand. Most visible with anything being held — a cup, a phone, a door handle.
- No camera jumps
- The framing shifting mid-clip without motivation. Reads as an accidental cut and breaks the continuity of a shot that was supposed to be continuous.
Where this falls short. A negative prompt is a request, not a constraint. None of these five is guaranteed to be honoured, and the set reduces the frequency of each failure rather than eliminating it. Treat a shot that still breaks hands as a re-roll rather than as evidence the prompt was wrong.
Why you shouldn't rewrite it
Because a negative set that varies is another source of variation.
The logic is the same as the argument against retyping character descriptions. You write "no broken hands" on shot one. By shot fourteen it's "no distorted hands, no extra fingers" — because you saw a bad hand, you improved the wording, and it seemed like a fix.
That's now a different instruction. Not a better one and not a worse one, just different from the fourteen shots before it. And you've introduced it into the middle of a sequence that was otherwise consistent.
Where this falls short. This is reasoning from how variation behaves rather than a measured finding. What's certain is that a set you retype varies and a set you paste doesn't — whether that variation changes output is a different question we haven't tested.
The set exists to prevent inconsistency. Editing it between shots makes it a source of inconsistency.
Where to keep it
Somewhere you paste from, not somewhere you remember.
That's the whole practice. A note file, a snippet manager, the top of your shot list — anywhere outside the prompt box you can copy from without thinking about it.
The failure mode is entirely about memory. Nobody sets out to change their negative set; they reach shot fourteen, don't have it in the clipboard any more, and type it from memory. Which produces something close and not identical, which is the problem.
When to change it
Between projects, not within one.
If a series consistently produces a failure the standard five don't catch, add a sixth — and add it to shot one of the next series rather than shot forty of this one.
The exception is a genuinely new problem appearing mid-series, which does happen when you switch models. In that case add the exclusion and add it to every remaining shot, so the change is a clean break rather than a gradual drift. Consistency from that point forward is what matters.
Where the negative set doesn't apply
Two modes where it's the wrong tool.
Motion. The prompt field there covers environment only, and motion verbs of any kind — including negative ones — conflict with the driving video. A negative set describing what the character shouldn't do is still describing what the character does.
Talking Actors. That field takes a script, meaning the actual words spoken. Anything you add gets read aloud, so a negative prompt appended to a script becomes dialogue.
- The standard set: no face swaps, no wardrobe changes, no broken hands, no floating props, no camera jumps
- Write it once and append it unchanged. Copy it rather than retyping it
- A negative set that varies is another source of variation, which is the thing it exists to prevent
- The failure is always memory. Keep it somewhere you paste from, not somewhere you recall
- Change it between projects, not within one. A new problem mid-series goes into every remaining shot
- It's a request, not a constraint. It reduces the frequency of each failure rather than eliminating it
- Don't use it in Motion — negative motion verbs still conflict with the driving video
- Don't use it in Talking Actors — that field is a script, so it would be read aloud
Instructions describing what shouldn't appear. For short drama series work the standard set is five exclusions — no face swaps, no wardrobe changes, no broken hands, no floating props, no camera jumps — appended unchanged to every prompt.
Because a negative set that changes between shots is itself a source of variation. Nobody sets out to change it — they reach shot fourteen, type it from memory, and produce something close but not identical. If you need a new exclusion, add it to every remaining shot rather than drifting into it.
They reduce the frequency of each failure rather than eliminating it. A negative prompt is a request, not a constraint, so a shot that still breaks hands is a re-roll rather than evidence the prompt was wrong.
No. Prompt length is free in every tool — only clip length, resolution and whether you select a real human actor drive cost. So there's no reason to trim the set to keep the prompt short.
No. Motion's prompt field covers environment, background, lighting and tone only, and any motion verb conflicts with the driving video. A negative instruction about what the character shouldn't do is still an instruction about the character.
Between projects, ideally. If a series consistently produces a failure the standard five don't catch, add it to shot one of the next one. If a genuinely new problem appears mid-series — which happens when you switch models — add it to every remaining shot so the change is a clean break rather than a gradual drift.
Write it once, paste it always
Prompt length costs nothing in any tool, so a full negative set is free. What it buys you is one fewer source of variation across a long series.
