# Clause-chain mechanism demo — rebuild sheet

A 49.8s fully-rendered explainer that takes you down between two teeth and then *inside* the plaque itself, one caption clause per beat — 1,236,383 views, 14,459 likes, by thebrainmaze.

**Why it works**

Every caption is a mid-sentence fragment of one continuous narration, so there is never a clean place to leave — the sentence you are reading was started before you arrived and is not finished when the beat cuts. What holds you underneath it is a look at the inside of your own problem: bacteria, bubbles and acid at a scale no camera can reach, so the claim reads as observed rather than argued.

**The beats**

| Time | What happens | On-screen text |
|---|---|---|
| 3.98s | Extreme macro on two upper front teeth, floss strand taut into the contact point, a clump of yellow-green debris packed against the gum | and food particles from areas / your toothbrush cannot |
| 11.94s | New angle, tighter: the floss descends into the tooth–gum junction through a mass of green rod bacteria and bubbles | disrupting bacterial colonies / before they cause harm |
| 19.90s | Camera is now *inside* the deposit — amber fluid, bubbles, bacteria, crystals, a dark open pore; no tooth or floss in frame | and release acids that weaken / enamel |
| 27.87s | Pull back: side view of three teeth on black, heavy calculus at the gumline, a blue floss-holder arm working the string down, debris streaming off | by clearing debris that irritates / the gums |
| 35.83s | Wide clean render of a full lower dental arch on pure black, a white floss pick inserted between the molars | by cleaning these tight spaces / daily |
| 43.79s | Close on a human lower face, smiling, flossing with a pick — a fine wireframe mesh over the skin shows this beat is rendered too | and lowers the risk of long / term dental complications. |

A small "TBM" channel watermark sits top-left in every frame. It is a channel mark, not part of the format.

**What carries the value**

The invisible made visible. The persuasion is the trip inside the deposit at 19.9s — bacteria, bubbles and acid shown at a scale that could not be filmed. The clause chain only stops you leaving; the reason to stay is that you are being shown the inside of a problem you were just told you have.

**Shoot it**

Honestly: five of the six beats are not shootable with a phone. They are 3D renders of an interior — no room, no light source you could name, no camera position that exists. The only beat a person could shoot is the last one: a close, chest-up-to-nose framing of {SUBJECT} using {PRODUCT}, plain dark background, soft even light from the front, no visible room, no wardrobe doing any work. Everything else has to be rendered or animated.

If you rebuild this for another brand, the shootable-adjacent version is macro on the real surface with a real product for the outer beats, and rendered interior beats in the middle — the structure survives that swap, because what the format needs is (a) captions that never finish a sentence and (b) a frame that recomposes to a new scale at every cut.

Rules that do carry over regardless: never hold a frame across two beats, never label anything on screen, and keep every caption in the identical lower-third position so the only thing changing is the words.

**Or generate it**

The beat to generate first is 11.94s — the product physically inside the problem, with the problem visible.

```
vertical 9:16 photoreal 3D medical render, extreme macro on {SUBJECT} — the treated
structure filling the upper left of frame and the soft tissue running across the lower
right, the two meeting at a tight junction in the centre — with {PRODUCT} entering
diagonally from the top of frame and pressing into that junction, and a dense mass of
green rod-shaped bacteria and small translucent bubbles packed along the junction and
spilling down the soft tissue; wet specular highlights on both surfaces, warm even
render light with no visible source, background falling off to black at the top right,
shallow depth of field, clinical render look, no labels and no on-screen text
```

*Motion:* camera pushes slowly in along the line of {PRODUCT} toward the junction, holding it centred as it makes contact, no cut inside the beat. The stills cannot show whether the original moves, so treat the push as a choice — then recompose to a completely new scale and angle for the next beat rather than holding this frame.

*Text overlay:* one clause per beat, two lines, centred in the lower third in the same position every time, white sans with a soft drop shadow — each clause a mid-sentence fragment that continues the one before and never completes:

`and {what is left behind} from {where it hides}` → `disrupting {the problem} before {it does harm}` → `and {what the problem does to you}` → `by clearing {what is removed}` → `by {the action} daily` → `and lowers the risk of {long-term consequence}.`
