# Inside-the-body reveal — rebuild sheet

A 33-second photoreal render that zooms inside an eye, paints the working part red, and explains it one word at a time. 25,202,363 views · 935,722 likes · @mr.brainboost.

**Why it works** — You are looking at a body part you own, rendered so real you check your own face, and then a hidden piece of it is coloured in and traced along its path, which is a thing you cannot see any other way. The overlay hands you one word per beat, so the sentence stays unfinished the entire runtime and leaving early means leaving mid-sentence.

## The beats

| Time | What happens | On-screen text |
|---|---|---|
| 2.66s | Extreme close-up on the side of a face — cheek, nose, closed eye. One thin tear runs down the cheek, catching a hard highlight. Near-dark, cool rim light, far side of the face black. | *(none visible)* |
| 7.98s | Macro on the inner corner of the eyelid — skin texture and pores fill the frame. A large flat red arrow points down at a tiny wet opening on the lid margin. | making |
| 13.29s | Photoreal eye filling the frame: brow hairs, separated lashes, blue iris. A glossy deep-red anatomical form sits under the upper outer eyelid, red fluid running down from it over the lashes. | lacrimal |
| 18.61s | Same eye, slightly wider and lower, lid half-closing. Red form still at the upper outer corner, a red line now along the lower lash line. Pale-blue backdrop behind the face. | a |
| 23.93s | Same framing, red form gone. Dark red fluid traced along the lower lid, running toward the inner corner. | drains |
| 29.24s | Camera pulls back to a three-quarter of the face — eye down to an open mouth. A red channel runs from the inner corner of the eye down inside the nose. | you |

**What the frames do not show.** These are six stills off a 33-second video, so the words between them are missing — "making / lacrimal / a / drains / you" is a fragment, not the full overlay sentence. Rebuild the sentence to your own beat count rather than trying to reconstruct this one. The stills also give no audio, no cut count between the sampled beats, and no proof of whether the first beat is a real photograph or a render — the later beats are clearly rendered.

## What carries the value

The coloured-in anatomy. A red gland and a red drainage channel painted inside an otherwise photoreal eye and nose, so it reads as looking through your own face at the part doing the work. Take the red away and there is nothing to watch; take the words away and it still mostly works.

## Shoot it

Be straight about this one: **the beats that carry it cannot be shot.** Frames 3–6 are renders — a real camera cannot see a gland under an eyelid. A phone gets you the frame the sequence opens on, and the interior is generated or animated.

What a phone can do:
- **Camera** — macro lens or the phone's macro mode, right up on the skin so the frame is nothing but the eye corner and cheek. Vertical. Camera close to still; a slow drift in, no handheld shake, no zoom.
- **Light** — one soft source from the front and slightly off-axis, everything else killed. Let the far side of the face fall to black. The tear only exists on screen if there is a hard highlight running down it, so keep one small specular source.
- **Wardrobe** — irrelevant and out of frame. Nothing on screen below the cheekbone. Bare skin, no makeup that reads as makeup, no jewellery, no visible clothing colour.
- **Subject rules** — no performance, no speaking, no eye contact with the lens. Skin unretouched: pores and marks are what make the render beats believable when they cut in.

Then the interior beats get generated to match that skin tone and light, and the red overlay is added on top.

## Or generate it

The beat worth generating first is the gland reveal — the moment the hidden part appears in red.

```
vertical 9:16 photoreal 3D render, extreme close-up of {SUBJECT} filling the frame — individual brow hairs, separated lower lashes, blue iris with one hard specular highlight, visible pores and faint skin marks, no retouching; {PRODUCT} rendered as a glossy deep-red translucent anatomical form sitting just under the upper outer eyelid, wet-looking, with red fluid running down from it across the lash line; plain pale-blue studio backdrop behind the face, soft even key from the front and a cool rim along the cheek, shallow depth so the far side of the face falls off, medical-illustration realism, no on-screen text
```

**Motion** — very slow push in on the eye with a small drift toward the outer corner; the face holds still and the only real movement is the red fluid tracking down the lid.

**Text overlay** — one word per beat, centred low in the frame, bold italic cyan with a dark edge, same position every time: `{word 1}` → `{word 2}` → `{word 3}` → … The words read as one continuous sentence explaining what {PRODUCT} does inside {SUBJECT}, and the sentence only finishes on the last beat.
