The "too perfect" tells
A take can be correct and still read as generated. These are the signs, each with the first fix to try.
A take can be correct and still read as generated. These are the signs, each with the first fix to try.
When to look: on every still, sheet, plate and take, before anyone else sees it, as the surface point of the reference bar (see The quality bar → The reference bar). On a take, look on the 1080p finish at full size, and on frames exported every 0.5 s (steps below). A video-analysis tool can report hair, hand and camera naturalness on a take; quote it as the tool's report, and your eye decides (see The quality bar → Judging motion honestly). Sheets are flat by design, so score them on colour, surface and the specific choice only, against the wardrobe and casting references.
The tells, each with its first fix [official guidance]. The blocks named are those of a Seedance prompt. In a still prompt, write the same words in the matching item of the still-prompt structure (see Still prompts, storyboard frames and diagrams → The still-prompt structure).
Tell | First fix |
Waxy or patchy skin | In PERFORMANCE, write two or three skin conditions the day would cause, as plain fact: "a little shine on the forehead after the walk, a shaving nick on the jaw". Re-attach the identity close-up (the approved still of the character's neutral face; see Photoreal anchors (Nano Banana Pro) → Close-ups and casting stills) |
An over-sharpened face | Delete every sharpening word from the prompt ("crisp", "razor-sharp", "ultra-detailed") and regenerate. Never upscale or sharpen the file to fix it. Judge the face on the 1080p finish, not the 480p draft |
Light with no visible source | In LIGHTING, name the source and say where it is: "the only light is the paraffin lantern on the table, frame left". Make sure the scene's first shot shows it or places it (see Light and look → One motivated, named source) |
Gimbal-smooth handheld | In CAMERA, write the operator's reaction: "the operator is a fraction late on her turn, overshoots a little as she stops, then corrects" (see Camera and lens → The honest, fallible operator) |
Motion at one even speed | Give each move a start that gathers, a travel and a settle, and write the settle in PHYSICS: "she sets the cup down; it rocks once, then stills" |
Extras moving in sync, or with no task | Write a BACKGROUND line that gives each extra one ordinary task, at their own tempo and in their own direction: "a woman at the kiosk counts her change; a boy drags a crate past, right to left" (see Making it feel real → Every visible extra has a job) |
Hair moving as one mass | In PHYSICS, name the strands and flyaways and the cause of each movement: "the draught from the open door lifts the loose strands at her temple" |
Everything brand-new | In TEXTURE (block 11 of the prompt), write one wear sign per garment and use traces where hands go: "a shine on the trouser knee, worn paint round the light switch". Keep the client's product pristine |
One sheen on every material | In LIGHTING, say how each material answers the key: "a soft sheen on her cheek, one hard glint on the tap, no shine on the cotton" (see Light and look → Materials under one light) |
A glow nobody asked for | Remove the effect words ("glow", "bloom", "radiant") and regenerate. Add effects only where the treatment asks, with a cause in frame. Never paint a glow out |
If a tell returns
Four tells have a second lever:
Waxy skin: remove any sharpening words and judge the skin on the 1080p finish. One retry may add "no smoothing, no airbrushed skin", with nothing else changed.
Even speed in a walk: in ACTION / TIMELINE, write the heel contact, the weight transfer and a hip shift: "her heel lands, her weight rolls forward, her hip drops on each step" (see Making it feel real → Weight and ease).
Hair as one mass: in PHYSICS, write the hair as a material with weight: "her hair lands a beat after her head turns, and the strands settle one by one".
Brand-new: carry the wear in the anchors as well: the sheets hold the wardrobe wear, and the plates hold the use traces (see Making it feel real → Skin, make-up and wear with a history).
If the take still looks plastic and no row fits
Write a TEXTURE block with 2–4 worn materials.
Frame the subject off centre.
Let the background fall into darkness past a stated distance: "everything past 4 m falls into dark".
Cut the number of subjects.
Use the film's own look line (see Light and look → The look line), not the clean fix (see Light and look → The clean look is a fix, not the default).
Rules that come with the table
One diagnosed change per retry, at the right level (see Video with Seedance → The failure table).
No pixel fixes (decided). A tell is never retouched, by hand or with any software on the frame. A take is regenerated with one change, or gets one model edit pass (one edit by the video model, for one local fault; see Video with Seedance → Joins, endings, extension and the video edit). A still or sheet gets up to two model edits, one change each, then a fresh image; a sheet that reads cheap is remade with better surface words, never rescued with a texture photo (see Photoreal anchors (Nano Banana Pro) → Edit passes, then a fresh image).
Grain never hides a tell. Every hard stop (hands, faces, lips, labels and Arabic text at full size; see The quality bar → The hard stops) is judged on the take as it came out, with no grain on it yet (see The grade and texture → Texture once).
Why: each row has at least one maker's guide behind it (Higgsfield, ByteDance's Dreamina, Luma), and several have creator support. Dreamina's guide warns that sharpening is how a face starts to look artificial. kaye.creatives' published realism block (in Sources) asks for the opposite of these tells.
