# S-46 Shot Brief V1
## Status
- Document status: created for direct S-46 generation.
- Execution status: prompt/spec created and used directly; S-46 image accepted by user.
- Project: `在路上`.
- Unit: `s46`.
- Source shot: `S-46`.
- Segment / time: Final four lines / `3:58-4:16`.
- Trial role: third shot in the five-shot visual test package.
- Style anchor: C泥泞里的星空.
## Purpose
S-46 tests whether the accepted C repair can become the MV's soul image as an actual shot.
Core test sentence:
> 低头看泥水,发现星空也在里面。
This shot is not about escaping the mud. It is about meaning appearing inside the mud.

## Shot Definition
Source table definition:
> Muddy puddle with broken star reflection and boot edge.
Expanded execution definition:
> A close-to-ground night or deep pre-dawn frame shows a real muddy puddle as the main subject. Broken star points are reflected in dark water and interrupted by mud, stones, ripples, and shoe marks. Only a small old boot edge, coat edge, or lower-body shadow may appear at the frame edge to connect the image to the traveler.
## Required Visual Content
The shot must include:
- 16:9 horizontal frame;
- low ground-level composition;
- irregular muddy puddle as the main subject;
- real wet mud, grit, stones, shoe marks, and rough puddle edges;
- dark water with broken star reflection clearly visible;
- old worn boot / lower-body trace only at the edge, under about `15%`;
- night or deep pre-dawn darkness;
- low-saturation poetic documentary realism.
## Composition Rules
Required composition:
- mud and puddle first;
- star reflection discovered inside the water;
- boot / person only peripheral;
- no face, no full body, no portrait;
- no clean mirror lake;
- no real sky as the main star field.
Recommended layout:
- puddle occupies center or lower-center;
- surrounding mud frames the puddle;
- star reflection appears inside dark water, broken by water ripples, stones, and irregular mud;
- old boot edge or coat hem enters from a far edge only.
## Character / Boot Rules
Only peripheral identity cues are needed:
- old road-worn boot;
- muddy boot edge;
- small coat hem / lower leg shadow if useful.
The boot must not become:
- a product closeup;
- shoe advertisement;
- fashion outdoor gear;
- clean new boot;
- the main subject.
## Color And Light
Preferred:
- dark blue-gray;
- wet black-gray;
- mud brown;
- coal black;
- small cold-white star points.
Lighting:
- night or deep pre-dawn darkness;
- weak water reflection;
- cold star glints in the puddle;
- no visible sun;
- no warm horizon;
- no firelight interference.
Avoid:
- sunrise or sunset;
- broad warm light;
- golden glow;
- fantasy portal light;
- bright clean Milky Way spectacle.
## Forbidden Drift
Reject if the image becomes:
- sunrise / sunset puddle;
- pretty landscape reflection;
- magic portal;
- fantasy lake;
- shoe or boot advertisement;
- clean mirror water;
- only mud with no stars;
- only stars with no mud;
- full person / face / portrait;
- text, logo, UI, watermark.
## Acceptance Criteria
S-46 passes only if:
1. The viewer first sees real mud and water.
2. Broken star reflection is clear enough to read.
3. The scene is night or deep pre-dawn, not sunrise or sunset.
4. The boot / traveler trace stays peripheral and under about `15%`.
5. The boot does not become a product shot.
6. The image is restrained and documentary-real, not fantasy.
7. It truly conveys "泥泞里,有星空".
## Next Action
Created and used for direct prompt/spec and image generation:
```text
slides/s46/s46-v1-prompt.md
slides/s46/s46-v1-image.png
slides/s46/s46-v1-review.md
```
No separate prompt review was required for this run because the user requested moving directly to the next generated shot and final image review.
