# Labelled cutaway mechanism — rebuild sheet

A 10.12s fully-rendered skin diagram: four labelled serums drip onto four labelled acne types, sink into a cross-section of the pore, and clear them — no person, no room, no camera move. 11,138,862 views · 83,705 likes.

**Why it works**

The frame never moves and the text never changes, so every bit of attention goes to the one thing that does move — the ingredient crossing from the surface into the body, which is the part a normal before/after can never show you. Running four problems side by side turns it from a claim into a sorting chart: the viewer stops scrolling to find which column is theirs, and the answer is only readable if they watch the fluid land.

**The beats**

| Time | What happens | On-screen text |
|---|---|---|
| 0.81s | Four glass droppers hang in a row — clear, amber, blue, orange. Below them, four untreated problems side by side on the skin: black dot, white bump, big red swollen lump, red bump with a white head. Below that, a cutaway of the pore channels under each one. | *(pinned block, below — identical in every frame)* |
| 2.43s | Each dropper releases. One bead of its own colour lands beside its own problem. Nothing has changed yet. | same |
| 4.05s | The beads become pouring streams that spread and engulf each lesion — the orange one opening a crater in the pustule, the blue one flooding the cystic lump. | same |
| 5.67s | **The mechanism beat.** Each fluid breaks the surface and runs down as a visible coloured column into the channel below it. The only frame where you see the active inside the body. | same |
| 7.29s | Droppers at rest. Surface calming — the black dot is a dimple, the lump is soft pink, the pustule has lost its head. The cystic mass in the cutaway has shrunk to a sliver. | same |
| 8.91s | Resolved. All four patches flat and even, the cutaway channels clear. The layout is exactly where it was at 0.81s. | same |

The pinned block, unchanged for the whole runtime:

> **WHICH SERUM WORKS BEST FOR YOUR ACNE?**
> down each dropper: Salicylic Acid · Niacinamide · Azelaic Acid · Benzoyl Peroxide
> under each column: **BLACKHEAD** ✓ Unclogs pores · **WHITEHEAD** ✓ Controls excess oil · **CYSTIC ACNE** ✓ Reduces deep inflammation · **PUSTULE** ✓ Targets acne-causing bacteria

**What carries the value**

The labelled cutaway. The persuasion is not the clear skin at the end — it is watching a named ingredient go *below the surface* into the channel and the named problem resolve there, in a frame that never moves so the change is impossible to miss. The four columns are what make it a chart instead of an ad: the viewer is looking for their own row.

**Shoot it**

This one is not shot — there is no camera, no room and no person anywhere in the six frames. It is a rendered diagram end to end. If you want the same structure with a real camera, the rule set that transfers is:

- **Camera:** locked on a tripod, one framing for the entire runtime, zero movement, zero cuts. Every beat must be the identical frame so the only legible change is the product doing its work.
- **Light:** flat and even, no shadow that shifts between beats — a shifting shadow reads as a cut and kills the illusion of one continuous frame.
- **Wardrobe / set:** none visible here, and adding either breaks the format. Plain neutral ground, no hands, no face, no branding in frame. The subject is the problem, not a person.
- **The one thing you must find a way to show:** the product crossing a boundary — into the pore, into the fabric, under the surface. A camera can do this with a cut-open prop, a clear vessel, or a sectioned sample. If you cannot show the inside, you do not have this format.
- **Text:** set it once, pin it for the full runtime, never animate it. Headline top, ingredient names on the products, problem name + one ✓ benefit line as a footer under each column.

**Or generate it**

Prompt the mechanism beat (5.67s) — the rest of the runtime is the same frame with more or less fluid.

```
vertical 9:16 3D medical-illustration render, locked front-on view, plain warm
beige background, composition in three stacked bands: across the top a row of
four identical clear glass dropper pipettes with brushed metal bulbs, each
holding {PRODUCT} in a different colour; a middle band showing the surface of
{SUBJECT} with four different problem states side by side in matching columns;
a lower cutaway cross-section beneath that surface showing the channels running
down into it. Each dropper is releasing a stream of {PRODUCT} that has broken
through the surface and continues as a visible coloured column down into the
channel directly below it. Even diffuse studio light, soft specular highlights
on the glass, clinical textbook-diagram look, high detail, no hands, no face,
no room, no on-screen text.
```

**Motion:** camera absolutely locked — nothing in the frame moves except {PRODUCT}, which falls from the dropper, spreads across the surface, then travels down into the cutaway. Generate every beat from the same seed frame so the diagram sits pixel-identical behind the change.

**Text overlay pattern** (pinned all runtime, never changing):

- Headline, top centre, serif all-caps: `WHICH {PRODUCT CATEGORY} WORKS BEST FOR YOUR {PROBLEM}?`
- Small vertical type down each dropper: `{ACTIVE}`
- Footer row under each column: `{PROBLEM TYPE}` in caps, with `✓ {WHAT IT DOES}` beneath

**What the frames do not tell us** — worth saying before anyone rebuilds it:

- No audio evidence. Stills cannot show whether this ran with a voiceover, trending sound, or silent. Decide that yourself.
- The small ✓ benefit lines were read off a low-resolution contact sheet; the wording above is the best read of them, worth confirming against the post before it goes in a brief.
- The six stills are evenly sampled, so any fast beat between them is invisible here. What is certain is that the framing and the text are identical in all six.
