# S-01 Shot Brief V1

## Status

- Document status: user approved for prompt/spec creation.
- Execution status: S-01 image accepted by user.
- Project: `在路上`.
- Unit: `s01`.
- Source shot: `S-01`.
- Segment / time: Prelude / `0:00-0:16`.
- Trial role: first shot in the five-shot visual test package.
- Style anchor: A｜风景主导型.

## Purpose

S-01 tests whether the MV can begin with the world before the traveler.

This is the lowest identity-risk trial shot because the traveler should not appear.

It must prove:

- the opening can be landscape-led, not portrait-led;
- A can establish the main road-film grammar;
- the road, mud, frost, cold distance, and empty world can carry the emotional premise before any character appears.

Core test sentence:

> 路先于人出现，世界先于人出现。

## Accepted Reference Assets

Primary style reference:

```

Style board reference:

```

Character references:

```text
none for S-01
```

Reason:

- S-01 should contain no person.
- Character references are not needed until shots where the traveler appears.
- This protects the opening from becoming a portrait-MV or hero-backshot image.

## Shot Definition

Source table definition:

> World appears before person; cold frosted muddy road, no person.

Expanded execution definition:

> A cold frosted muddy road appears in a large empty world before the traveler enters the MV. The viewer should feel the road, distance, damp ground, and cold air before thinking about a person.

## Required Visual Content

The shot must include:

- 16:9 horizontal frame;
- large landscape / world-first composition;
- muddy road or worn dirt road extending into distance;
- cold dawn, pre-dawn, or early morning atmosphere;
- thin frost or cold wet ground texture;
- low saturation;
- documentary-real road-film texture;
- no visible person.

The road should feel long enough to carry the whole MV's premise:

> 这不是一个人要展示自己，而是一个人即将进入一条比自己更长的路。

## Composition Rules

Required composition:

- environment first;
- road as primary line;
- wide or very wide framing;
- enough sky / ground / distant world to make the frame breathe;
- no centered hero subject;
- no foreground object taking over the shot.

Recommended layout:

- road begins near lower frame and travels toward the distance;
- horizon sits in upper-middle or upper-third area;
- cold sky and rough ground both remain visible;
- mud/frost detail is readable but not a closeup.

## Color And Light

Preferred:

- cold gray;
- earth brown;
- wet dark blue-gray;
- subdued frost white;
- very restrained pale dawn edge if needed.

Avoid:

- golden tourism sunrise;
- warm inspirational glow;
- saturated scenic landscape;
- commercial orange-blue blockbuster grading;
- bright noon.

Important note:

- The accepted A source image contains a warmer horizon.
- S-01 may keep a faint cold dawn edge, but must not become a beautiful sunrise postcard.

## Texture Requirements

Must feel real:

- wet mud;
- rough road ruts;
- frost or cold dampness;
- worn ground;
- natural sky;
- distant empty terrain.

Do not over-polish the ground or make the scene clean.

The opening should feel quiet and physically cold, not decorative.

## Forbidden Drift

Reject if the image becomes:

- travel advertisement;
- scenic tourism image;
- inspirational poster;
- hero backshot;
- portrait MV opening;
- clean fantasy landscape;
- obvious AI concept-art spectacle;
- over-bright sunrise;
- road with a clearly visible person;
- text, logo, UI, symbols, watermark.

## Relation To Other Trial Shots

S-01 sets the baseline for all later shots:

- before S-10 city pressure, the road/world must already exist;
- before S-46 muddy starlight, mud and road texture must already be real;
- before S-47/S-51 firelight, the film must already feel restrained and landscape-led.

If S-01 fails into postcard scenery or hero imagery, the later full MV will likely drift.

## Acceptance Criteria

S-01 passes only if:

1. The first impression is road/world/environment, not person.
2. No visible traveler appears.
3. The road feels long, cold, muddy, and real.
4. The image belongs with the accepted A/B/C/D style board.
5. The shot avoids tourism, inspirational, and scenic-ad drift.
6. The frame can plausibly open the MV before the character enters.
