Interior, Wayfinding & Delivery Video Briefs

六条空间类视频简报——不得放大房间的室内预览、走廊导视、货运自行车卸货、最后一米包裹交接、只移动家具的布局变化，以及站台安全线场景。

这组简报最鲜明的约束是对空间的诚实。室内类简报要求从已获授权的真实房间照片出发，禁止拉伸空间、移除暖气片、增加窗户或做豪华化升级；书桌边缘必须留在画面中充当比例参照。布局转换那条是首尾帧任务，两帧的机位与房间几何完全相同，中间只允许家具位置变化。交通类简报要求旅客始终停在站台安全线之后，且时刻表不可读；所有简报都禁止编造班次时间、租赁承诺、认证式尺寸标注、商标与水印。

# FLUX 3 architecture and mobility prompts

Six briefs focused on space, visible routes and clear object handling. Generated visuals cannot certify measurements, accessibility, vehicle safety or actual service availability.

## B01 — A corner without enlargement

**Use:** truthful interior-preview concept · **Mode:** image to video  
**Input:** licensed first frame of the actual room corner  
**Format:** 16:9, 15 seconds · **Adjust:** pan distance, not architecture.

```text
Start exactly from the supplied room photograph. Preserve the wall junction, desk, chair, radiator, window and every visible obstruction. No person enters.
00:00–00:05 — Hold the initial view at a natural eye level. Show stable vertical lines and believable room dimensions.
00:05–00:10 — Pan slowly from desk toward the adjoining visible wall. The desk edge remains in view as a scale reference. Do not move through furniture.
00:10–00:15 — Stop on a balanced corner composition. The same window light falls in the same direction.
AUDIO: Quiet interior room tone only. No new street or appliance event.
LOCK: Wall positions, desk proportions, furniture count, window height and finish.
TEXT: None; add verified dimensions separately if needed.
AVOID: stretching the room, removing radiator, extra windows, luxury upgrades, impossible lens expansion, rental promises, branding or watermark.
```

## B02 — The sign and the decision

**Use:** wayfinding design visualization · **Mode:** image to video  
**Input:** approved first frame of a corridor junction with existing signage  
**Format:** 16:9, 18 seconds · **Adjust:** walking speed after route verification.

```text
Use the supplied image of a corridor junction and one consenting visitor. Preserve the corridor layout and existing sign placement. Do not invent or rewrite sign text.
00:00–00:06 — Static wide shot. Visitor stops before the junction and looks at the sign, leaving the walking route clear.
00:06–00:12 — Visitor turns toward the branch already indicated in the approved scene brief, then begins walking at a normal pace. Keep the same bag and clothing.
00:12–00:18 — Camera follows a short distance, stopping before the source-supported space ends. Do not reveal a destination absent from the reference.
AUDIO: Footsteps, light bag movement and corridor ambience. No fabricated station announcement.
LOCK: Sign, junction, travel direction and visitor identity.
TEXT: Preserve existing text where readable; no new overlays.
AVOID: unsupported route advice, changing arrows, new doors, teleportation, misleading accessibility claims, extra people or watermark.
```

## B03 — Park, then unload

**Use:** stationary cargo-bike delivery concept · **Mode:** text to video  
**Format:** 16:9, 20 seconds · **Adjust:** parcel size within the cargo box.

```text
Show an adult courier beside a stationary unbranded cargo bicycle on a broad pedestrian forecourt. The bike is already securely parked on its stand. One small cardboard parcel sits in the front cargo box.
00:00–00:06 — Locked side view. Courier checks the bike is steady with one hand on the frame. No traffic or riding.
00:06–00:13 — Courier opens the existing cargo-box lid, lifts the one parcel with both hands and places it on a nearby low bench.
00:13–00:20 — Close the lid, pick up the parcel again and walk slowly toward an already visible doorway. Hold before entering.
AUDIO: Latch, cardboard, footsteps and quiet outdoor ambience. No narration or music.
LOCK: Wheel count, stand, cargo-box geometry, one parcel and courier clothing.
AVOID: moving bike during unloading, changing wheels, oversized load, delivery-time claims, address labels, logos, unsafe road scene or watermark.
```

## B04 — A parcel changes hands

**Use:** last-meter logistics illustration · **Mode:** text to video  
**Format:** 9:16, 18 seconds · **Adjust:** reception decor, retaining the handoff sequence.

```text
At a fictional building reception desk, one courier holds one plain small parcel. A receptionist stands behind a clear counter. No personal information appears.
00:00–00:06 — Medium two-shot. Courier places the parcel on the counter and keeps a hand beside it, not on top of a screen.
00:06–00:12 — Receptionist inspects the blank side, nods and draws the parcel closer. Courier releases it only after the receptionist's hand makes contact.
00:12–00:18 — Receptionist places it in one existing shelf bay. Courier steps back and exits along the visible path.
AUDIO: Cardboard on counter, footsteps and quiet reception ambience. No speech or confirmation beep without a device.
LOCK: One parcel, same orientation markings, shelf bay and people.
AVOID: generated signatures, fake tracking details, duplicate parcels, guaranteed delivery claims, teleporting package, brands, captions or watermark.
```

## B05 — Furniture, not new walls

**Use:** interior layout concept transition · **Mode:** start/end to video  
**Input:** two approved frames with identical camera and room geometry  
**Format:** 16:9, 20 seconds · **Adjust:** furniture positions only through the endpoints.

```text
Match the first reference frame of a small reading room and finish on the approved second frame. Walls, windows, doors and floor remain identical. Only one lightweight chair and one side table change position.
00:00–00:06 — Hold the opening composition, then an adult enters along the existing clear doorway.
00:06–00:14 — The person lifts the chair and carries it to its end-frame position, then moves the side table separately. Objects have weight and never slide through each other.
00:14–00:20 — Person exits by the same doorway. Camera stays locked; settle exactly into the end-frame furniture arrangement.
AUDIO: Footsteps, restrained wood contacts and unchanged room tone. No score.
LOCK: Architectural dimensions, furniture geometry, light and one continuous room.
AVOID: walls morphing, furniture duplicating, magically moving objects, renovation claims, impossible clearance, extra décor, text, logos or watermark.
```

## B06 — Waiting behind the line

**Use:** calm transit-environment concept · **Mode:** text to video  
**Format:** 16:9, 15 seconds · **Adjust:** fictional station materials, keeping safe separation.

```text
Create a generic modern train platform with a clearly visible edge boundary and a bench well behind it. One adult traveler in a tan jacket stands beside a closed suitcase, also well behind the boundary. No train arrives.
00:00–00:05 — Locked wide view establishes the platform edge, suitcase and traveler with ample space between them and the boundary.
00:05–00:10 — Traveler retracts the suitcase handle and moves it next to the bench, then sits without obstructing the walking path.
00:10–00:15 — Hold the quiet waiting posture. Distant overhead lights remain steady; no schedule board is readable.
AUDIO: Soft station ventilation, suitcase wheels and bench contact. No live timetable announcement or approaching train.
LOCK: Boundary position, platform geometry, one suitcase and traveler.
AVOID: stepping across the edge, train-induced wind, extra luggage, invented service times, unsafe crowding, signs, logos or watermark.
