What to do when a generated scene comes back wrong

You have a storyboard of 18 scenes. Seventeen generate fine and scene 9 comes back wrong every time: the wrong animal, or an action nobody can read, or a room that looks nothing like the rest of the video.

The instinct is to rewrite the prompt and try again, which is often the one move that makes things worse. A prompt that produced good scenes does not become a bad prompt because one output failed. Before touching it, work out which of the three layers failed.

Three layers, three different failures

Every scene prompt is built from the same three parts: who is in it, what they are doing, and where they are. Read the bad output once and name the layer that broke. The fixes are different for each, and applying the wrong one is how a working scene gets destroyed.

• •The character is wrong: the shape, colour or face has drifted from every other scene
• •The action is wrong: the pose is muddled, there are too many things happening, or nobody is doing anything
• •The setting is wrong: the place is generic, or the light and mood no longer match the video

If the character is wrong: reroll, do not rewrite

Character drift is a dice roll, not a decision. The model re-rolls everything you left unsaid on every generation, and occasionally it rolls badly. Fixing the dice is not what editing words is for.

Regenerate the same prompt unchanged, three or four times, and take the best. If your tool accepts a reference image, attach the character sheet. A bad roll followed by a rewritten prompt throws away the clause that produced the seventeen good scenes, and the new wording will drift somewhere you are not looking.

This is the same rule from keeping a character consistent: never edit the identity clause to fix one scene. Edit it only when most scenes are wrong, because that is the only time the clause is the problem.

If the action is wrong: the prompt asked for too much

An unreadable pose almost always has a cause in the words: two verbs in one shot. "Waving from the doorway while holding the basket" asks the model to stage two actions, and it stages neither clearly.

Keep the one verb that carries the scene and cut the other. If both actions matter to the story, that is not a prompt problem, it is a storyboard problem: the moment needs two scenes, one for each half.

If the setting is wrong: name what you never named

When the place comes back generic — a room, a field, a street that matches nothing else in the video — the setting words were thin. The model fills unspecified space with the average of everything it has seen, and the average of everything is not your world.

Name the two or three things that make the place yours: what it is, what stands in it, where the light comes from. Look at the scene that establishes the location — your scene 1 — and borrow its nouns.

The four fixes, in order

1. 01

   Reroll unchanged

   Two or three times, with the reference image attached. This fixes character drift and costs nothing. Most single bad scenes end here.

2. 02

   Cut to one verb

   If the action is unreadable, remove the second action and regenerate. Do not rephrase the two actions into different words for the same two actions.

3. 03

   Name the missing nouns

   If the setting is generic, add what is standing in it and where the light comes from, in the same words the establishing scene uses.

4. 04

   Split the scene

   If it still fails, the moment holds too much. Make it two shorter scenes and hand the spare second to the final hold.

Notice the order: the cheapest fix first, and the one that changes the storyboard last. Most people start at the end, rewriting the scene when a reroll would have done.

When the scene is the problem

Occasionally the picture is fine and the scene is wrong: it asks for something the medium is bad at, like a character seen from behind turning round, or three animals crossing a stream. Some shots are expensive no matter how they are worded.

A storyboard can change. If a scene keeps failing after the four fixes, re-map it to a neighbouring line of the song and prompt a shot the medium likes: one character, one action, front or side on, light from one direction. Nobody watching knows what scene 9 was supposed to be.

The assembly order that ships with every Blue Flower kit front-loads the two reference scenes — the location, then the character — so most bad scenes never happen, and the four fixes above are the backup for the ones that still do.
