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:

visual-system/style/style-anchor-board-v1.png

Character references:

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.
