Locate who was added and when
Review inputs and output rather than label everything “duplication.”
| Observation | First check |
|---|---|
| Extra person in first frame | Actual start image against storyboard |
| Style-image model enters scene | Role mistakenly treated as full-image copying |
| Original and extra figure coexist after occlusion | Identity, route and reappearance state |
| Exit followed by another person returning | Distinguish return from new entry |
| Same person appears in mirror | Established reflection, not necessarily extra cast |
These are diagnostic directions, not proven technical causes. Without output, flag ambiguous requirements rather than claim a failed generation.
Separate visible, off-screen and entering cast
Do not paste the episode’s full cast into a shot. List visible people and off-screen participants affecting action or sound.
This manual check card is not a native skill output. In an original alterations-shop scene, owner Ye Qing passes behind a garment rack and returns beside the fitting mirror. Customer Tang Zhen stays seated in the foreground. A courier calls only from outside.
| Entry | Position and change |
|---|---|
| Ye | Passes behind right-side rack; same owner returns |
| Tang | Seated in foreground throughout |
| Courier | Outside voice; no on-screen entry in this shot |
| Visible count | Two at start; only Tang visible during full occlusion; same two at end |
| Preserved facts | Location, outfits and Tang’s position; no added people beyond rack |
Occlusion changes visible count without removing a person from the story. “Two fully visible faces throughout” would contradict it. If the next shot shows the courier, update that shot’s visible cast.
Keep character sheets, style images and start frames distinct
A multi-view character sheet shows several views of one person, not three identical people in the shot. It can provide identity and look; the actual start frame follows the storyboard’s visible count, positions and held objects. Prepare a matching start image or supply the chosen reference mode’s required text rather than use the sheet as a scene frame.
A style image supplies color, material and visual language. Its passerby does not belong in this shop, and temporary people in a geography image do not automatically become cast. Fix an input conflicting with the scene; negative wording does not establish that existing pixel risks are repaired.
Bind stable identities through the chosen model’s reference method. Example character names are not universal identity-lock parameters. Follow the reference-role guide and current project profile.
Original repair: the same owner behind the rack
The accepted storyboard has Ye pass behind the rack and return beside the mirror; the courier speaks outside. The mirror stays fixed, but this framing shows no character reflection. This is an ungenerated design comparison.
Ambiguous:
Reference the character board and fashion-shop photo. She goes behind the rack; another person comes out. Someone at the door calls “Delivery.” Always two people, no duplicates.
“Another person” contradicts a returning owner. The voice lacks an off-screen distinction, and continuous visible count conflicts with occlusion.
Revised:
Begin with the accepted start frame: Ye Qing stands right of the rack; Tang Zhen sits in the foreground. The courier first calls from outside, “Delivery.” The courier stays off screen. Ye looks toward the door, then passes behind the rack toward the fitting mirror. While Ye is fully hidden, only Tang is visible. Ye reappears on the mirror side of the rack as the same Ye in the same outfit. End with Ye beside the mirror and Tang seated in the original place. Fixed camera makes the route readable. Retain these two people in the shop without added passersby. This framing shows no character reflection.
Identity, route, off-screen voice and end state are distinct without deleting the courier from the story. Bind Ye and Tang to accepted references when submitting; natural-language text does not replace image mapping.
Check output around occlusion
Review start, pre-occlusion, hidden interval, reappearance and end. Check identity, outfit, position and count. Does an original figure remain before the rack while another emerges? Does the courier enter contrary to the shot? Record the visible defect and moment instead of marking the whole shot simply “failed.”
If inputs and boundaries are clear and the defect is occasional, retry within budget. If it recurs at the same point, revise requirements or split the route into clearer shots. Revise the storyboard first while preserving the owner, voice timing and end obligation rather than deleting movement.
A prompt repair is not a repaired video. Accept only output that removes the extra person while retaining intended cast and story. The reroll-or-rewrite guide covers routing choices.
FAQ
Is “no extra people, no duplicates” enough?
It can be a useful exclusion, but does not replace correct inputs and concrete state. Specify intended visible cast, off-screen participants and occlusion paths. Do not force a two-person scene down to one.
Do it with the skill
Use $short-drama-video-prompts to check extra-cast risks against accepted storyboard, reference roles, visible cast and off-screen voices. Preserve identity along occlusion and the required end state. Report only observed defects when output exists. Revise text without generating video.
