# Assemble-then-state-swap — rebuild sheet

A 43-second build-and-prove: one person assembles an ergonomic chair on the carpet, then a second person sits in it and the same wide frame is shown twice — upright and working, then reclined and resting. 21,938,722 views · 452,861 likes, by derek.she.

**Why it works**

The two wide shots at 24s and 31s are the same room, same camera position, same person — so the only thing that changed is the body, and the range reads instantly instead of being claimed. The floor-level assembly beats before it are what buy that: gloved hands fitting a cylinder into a base on real carpet make the object real, so the payoff frame lands as a thing that exists rather than a showroom photo.

**The beats**

| Time | What happens | On-screen text |
|---|---|---|
| 3.44s | Close side view, camera low near the floor. Product reclined almost flat, a person lying back across it in a cream sweater and light-blue jeans. Face not shown. Pale wall, blinded window, grey carpet. | to help her change that. |
| 10.31s | High angle down onto the carpet. One hand in a white work glove with a mint cuff lowers the black cylinder into the five-star base lying on the floor. Parts still separate. | and then install the base |
| 17.18s | Macro on the armrest control pad — three buttons, a lock icon and two arrows — index finger pressing the right arrow. Curved monitor and desk out of focus above. Dim light. | If you press these arrows |
| 24.06s | Wide side-on of the whole office corner at standing height. The person sits upright at the desk, working; product in full profile. Desk under a blinded window, wide monitor with a light bar showing a board, round speaker on a tripod, white door at right. | 105 degrees for deep focus |
| 30.93s | The same wide frame, near-identical camera position. The person is now reclined nearly flat, head back, arms folded. The monitor has switched to something dark and red. Only the body and the screen changed. | relax and watch a movie. |
| 37.8s | Back in close on the side of the product, camera low. The segmented articulated backrest and the piston beneath it are flexed open with the person's back pressed into them. | that relieves any tension from your back |

**What carries the value**

The same body in the same wide frame at two opposite extremes — upright at 24s, near-flat at 31s. The range is proved by contrast, not stated. Everything before it is the setup that makes the contrast believable.

Two honest notes on the evidence. **The opening is not in these frames** — the first still is at 3.44s and its caption, "to help her change that.", is already mid-sentence, so whatever the hook was in the first three seconds is unseen and is not reconstructed here. The post's caption ("My girlfriend's back is always hurting, so I decided to get her a nice ergonomic chair… She likes it a lot!") suggests a problem-statement open, but that is the caption talking, not a frame. **The audio is also unread** — the on-screen text is clearly voiceover subtitles, so there is a spoken track carrying the sentence that these six stills only sample.

**Shoot it**

Phone, vertical, no tripod needed except for the pair.

- **Camera.** Four positions, and only four. Low and close beside the product for the open and the close (the phone almost on the floor, product filling the frame). High angle straight down onto the carpet for assembly. Macro on the control for the how-it-works beat. Then back to standing height, side-on, a few feet out, for the wide pair. The wide pair is the one shot that must not move — mark the floor, shoot the upright state and the reclined state from the exact same spot, back to back. Everything else can be handheld.
- **Light.** Daylight through a window with blinds, nothing added. The frames show no fixture and no fill. The control close-up is noticeably darker than the rest — that is fine, leave it; the unevenness reads as real.
- **Wardrobe.** One oversized cream sweater and light-blue jeans, worn in every beat the body appears in, so the two wide shots match. White work gloves with a coloured cuff for the assembly hands — they read as "being built", not as a hand model.
- **Cast.** Two people, neither of whom performs. One is a pair of gloved hands. The other is a body with the face never shown — hair, a shoulder, the back of a head. Nobody talks to camera.
- **Room.** A real desk against a real wall. The frames show a keyboard, small plants, a monitor light bar, a speaker on a stand, a door. Leave that clutter in; it is what stops the wide frame reading as a product shot.
- **Text.** Record a voiceover and burn the captions in as one continuous sentence — one fragment per beat, none of them finishing on its own. That is the retention device.

**Or generate it**

Image prompt for the payoff beat (30.93s, the reclined half of the pair):

```
vertical 9:16 photograph, wide side-on view of a home-office corner at standing eye
height from a few feet back, {SUBJECT} in an oversized cream sweater and light-blue
jeans reclined far back in {PRODUCT} with head resting back and arms folded, the
product shown in full profile; a light wood desk against a pale wall under a window
with white horizontal blinds, a wide monitor with a slim light bar clipped to its top
edge, keyboard and small green plants on the desk, a white interior door at the right
edge, grey low-pile carpet; even daylight through the blinds, no visible light fixture,
phone-camera look, slight grain, no retouching, no on-screen text, face not shown
```

**Motion:** hold the wide side-on frame near-still with only faint handheld drift, so the single thing changing in frame is {SUBJECT}'s body and {PRODUCT} moving from upright to reclined — generate the upright beat and the reclined beat from the same seed frame so the room matches exactly.

**Text-overlay pattern:** running voiceover captions, white bold sans-serif, centred at mid-frame height, one spoken fragment per beat with the sentence continuing across beats so no single line completes on its own:

`"to help {them} change that." → "and then install the {part}" → "If you press {control}" → "{setting} for {use case}" → "{second use case}." → "that {benefit} from your {body part}"`
