# Character Anchor Brief V1
|
|
|
|
## Status
|
|
|
|
- Document status: pending review.
|
|
- Execution status: brief only; do not generate images from this file.
|
|
- Source basis: primary character intake files plus approved trial plan.
|
|
- Next gated action after approval: create `character-anchor-prompt-v1.md` through the `gpt-image-2` Skill workflow.
|
|
|
|
## Purpose
|
|
|
|
This brief defines the project-specific character anchor requirements for `在路上`.
|
|
|
|
It is not a final image prompt. It is the execution source that the next Skill-based prompt document should use.
|
|
|
|
The character anchor must answer:
|
|
|
|
> When the traveler appears as a small side view, back view, or distant figure in later MV shots, can we still tell this is the same person?
|
|
|
|
## Source Files Actually Used
|
|
|
|
Primary sources:
|
|
|
|
- `intake/阶段四-人物锚点板策划说明.md`
|
|
- `intake/阶段四-人物锚点板页面结构建议稿.md`
|
|
- `intake/阶段四-人物锚点板文案标注稿.md`
|
|
|
|
Planning gate:
|
|
|
|
- `visual-system/characters/character-anchor-trial-plan.md`
|
|
|
|
Not used in this brief:
|
|
|
|
- User source photo: not read yet. It will be handled in the prompt stage as an identity reference if the file is readable and approved for use.
|
|
- `character-anchor-board-v1.md`: treated as a non-generation-ready draft, not as an authoritative source.
|
|
|
|
## Source Photo Role
|
|
|
|
The user source photo path is:
|
|
|
|
```text
|
|
C:\Users\wangq\Pictures\照片\photo.jpg
|
|
```
|
|
|
|
Role in later prompt work:
|
|
|
|
- identity reference;
|
|
- face direction and lived-person basis;
|
|
- age, facial structure, hair / stubble direction if visible;
|
|
- not an edit target;
|
|
- not a passport-photo style target;
|
|
- not a requirement to reproduce the exact original photo pose, lighting, background, or clothing.
|
|
|
|
Expected transformation:
|
|
|
|
> Use the source photo to keep a recognizable human basis, then translate the figure into the `在路上` traveler identity: weathered, restrained, road-worn, and usable across distant landscape-led shots.
|
|
|
|
The prompt stage must explicitly label this input as `identity reference`.
|
|
|
|
## Character Role In The MV
|
|
|
|
The traveler is not the visual protagonist in a portrait-MV sense.
|
|
|
|
He is a moving coordinate inside a larger world:
|
|
|
|
- world before face;
|
|
- road before pose;
|
|
- silhouette before expression;
|
|
- continuation before victory.
|
|
|
|
The character anchor must support wide shots, back shots, side shots, muddy-road shots, city-edge shots, and night-fire shots.
|
|
|
|
## Identity Definition
|
|
|
|
### Core Identity
|
|
|
|
- 50-year-old male traveler.
|
|
- Based on the user's self-image direction, but translated into a road-film character.
|
|
- Worn by life and systems, but still walking.
|
|
- Not a celebrity, fashion model, homeless figure, drunk figure, or hero-poster protagonist.
|
|
|
|
### Temperament
|
|
|
|
- weathered rock feeling;
|
|
- warm but tired;
|
|
- lonely but steady;
|
|
- silent, not defeated;
|
|
- tired but not broken;
|
|
- rugged but not collapsed;
|
|
- road-worn dignity.
|
|
|
|
### Body And Presence
|
|
|
|
- body should feel capable of continuing forward;
|
|
- neither frail nor gym-styled;
|
|
- not an inspirational heroic body;
|
|
- posture may be slightly weighted, but not defeated;
|
|
- gait should be real, slow, and stable.
|
|
|
|
## Appearance Anchors
|
|
|
|
These features should remain stable across views and later shots.
|
|
|
|
### Head / Face
|
|
|
|
- dark, slightly messy hair;
|
|
- visible stubble;
|
|
- middle-aged weathering;
|
|
- warm tiredness;
|
|
- no polished grooming;
|
|
- no fashion portrait expression;
|
|
- no dramatic heroic stare.
|
|
|
|
### Clothing
|
|
|
|
- dark gray / dark khaki / coal-black long traveler's coat;
|
|
- dark restrained inner layer;
|
|
- coat has light use traces but is not torn or theatrical;
|
|
- coat length and silhouette must remain stable enough for later back-view recognition;
|
|
- clothing is practical and road-worn, not branded outdoor fashion.
|
|
|
|
### Props
|
|
|
|
- old practical backpack;
|
|
- used but not broken;
|
|
- medium volume, not oversized, not tactical-fashion, not luxury gear;
|
|
- stable enough to identify the traveler from behind.
|
|
|
|
### Boots
|
|
|
|
- old walking boots;
|
|
- can carry mud;
|
|
- durable and road-appropriate;
|
|
- not new fashion boots;
|
|
- not shoe-ad closeup styling.
|
|
|
|
## Required Main Board Scope
|
|
|
|
The main anchor board should be one 16:9 horizontal page on a clean shallow gray-white or very light warm-gray background.
|
|
|
|
The main board should prioritize identity consistency and execution usefulness over decorative beauty.
|
|
|
|
### Required Visual Cells
|
|
|
|
| ID | Cell | Purpose | Priority |
|
|
| --- | --- | --- | --- |
|
|
| A1 | Front full body | Establish age, body proportion, coat front, inner layer, and overall temperament. | Required |
|
|
| A2 | Side full body | Establish side silhouette, jaw/stubble profile, coat fall, and backpack volume. | Required |
|
|
| A3 | Back full body | Establish back-view recognition, backpack placement, rear hair outline, and coat hem. | Required |
|
|
| B1 | Half-body state | Confirm face age, hair, stubble, eye mood, tired dignity. | Required |
|
|
| B2 | Walking side | Confirm gait, coat movement, body weight, and forward motion. | Strongly recommended |
|
|
| B3 | Walking back | Confirm the most important later MV silhouette. | Strongly recommended |
|
|
| C1 | Coat / inner layer detail | Lock clothing system and color range. | Recommended |
|
|
| C2 | Backpack detail | Lock the back-view identity prop. | Recommended |
|
|
| C3 | Boots detail | Lock the road / mud / walking identity prop. | Recommended |
|
|
|
|
### MVP Board If Generation Capacity Is Limited
|
|
|
|
Minimum acceptable first board:
|
|
|
|
1. front full body;
|
|
2. side full body;
|
|
3. back full body;
|
|
4. half-body state;
|
|
5. short boundary notes or empty annotation zones.
|
|
|
|
If the model struggles with a full 9-cell board, the next repair strategy should be split generation rather than forcing all requirements into one overloaded image.
|
|
|
|
## Layout Guidance
|
|
|
|
Preferred structure:
|
|
|
|
- top: title / board identity area;
|
|
- left: three-view core;
|
|
- middle: state views;
|
|
- right: clothing and prop breakdown;
|
|
- bottom: compact rule / boundary area.
|
|
|
|
The board should look like a practical film pre-production reference sheet, not a colorful character poster.
|
|
|
|
### Background
|
|
|
|
Use:
|
|
|
|
- shallow gray-white;
|
|
- very light neutral gray;
|
|
- very light warm gray.
|
|
|
|
Avoid:
|
|
|
|
- landscape background;
|
|
- city background;
|
|
- muddy road background;
|
|
- campfire background;
|
|
- strong gradient;
|
|
- dramatic studio shadow;
|
|
- promotional poster background.
|
|
|
|
Reason:
|
|
|
|
The background must not interfere with silhouette, coat color, hair shape, backpack form, or boot details.
|
|
|
|
## Text And Label Strategy
|
|
|
|
Labels matter, but generated readable text is not reliable enough to carry the source of truth.
|
|
|
|
For this trial, use this split:
|
|
|
|
### Image Model Responsibility
|
|
|
|
The image may include:
|
|
|
|
- simple visual zones;
|
|
- small label-like blocks;
|
|
- thin annotation lines;
|
|
- empty callout zones;
|
|
- minimal non-critical labels if the model can render them cleanly.
|
|
|
|
The image must not be trusted as the only source for exact Chinese text.
|
|
|
|
### Document Responsibility
|
|
|
|
This brief and later prompt/review files carry the authoritative labels:
|
|
|
|
- age;
|
|
- temperament;
|
|
- clothing anchors;
|
|
- prop anchors;
|
|
- allowed drift;
|
|
- forbidden drift;
|
|
- review checklist.
|
|
|
|
### Later Layout Responsibility
|
|
|
|
If a final readable board with exact Chinese labels is needed, add or repair labels in a later page/layout step rather than relying only on image generation.
|
|
|
|
## Allowed Drift
|
|
|
|
These variations are acceptable if identity remains stable:
|
|
|
|
- mild mud or dust;
|
|
- wind-worn texture;
|
|
- slightly messy hair;
|
|
- tired eyes;
|
|
- used clothing traces;
|
|
- restrained ruggedness;
|
|
- small pose variation between views.
|
|
|
|
## Forbidden Drift
|
|
|
|
Avoid:
|
|
|
|
- homeless stereotype;
|
|
- drunk stereotype;
|
|
- collapse or spiritual defeat;
|
|
- fashion model styling;
|
|
- polished travel blogger image;
|
|
- luxury outdoor gear;
|
|
- heroic poster pose;
|
|
- arms-open inspirational posture;
|
|
- celebrity portrait look;
|
|
- glossy game concept art;
|
|
- anime / cartoon styling;
|
|
- fantasy armor or costume;
|
|
- cyberpunk / neon / sci-fi clothing;
|
|
- passport-photo style;
|
|
- direct front-facing glamour portrait;
|
|
- shoe advertisement framing;
|
|
- background scene becoming more important than the character.
|
|
|
|
## Review Questions
|
|
|
|
Use these questions after the first generated board.
|
|
|
|
1. Do front, side, and back views clearly look like the same person?
|
|
2. Does the back view work without relying on the face?
|
|
3. Does walking side / walking back look natural, not posed?
|
|
4. Is the traveler tired but still dignified?
|
|
5. Are coat, backpack, and boots stable enough to guide later shots?
|
|
6. Does the board avoid homeless, drunk, fashion, hero, and travel-blogger drift?
|
|
7. If the figure is mentally scaled down to 1/8 or 1/12 of the frame, does the silhouette still read?
|
|
8. Is this board useful for later `s01/s10/s46/s47/s51` prompt work?
|
|
|
|
## Trial-Specific Validation
|
|
|
|
This brief should support the next prompt-stage validation:
|
|
|
|
1. Can the `gpt-image-2` Skill template be adapted from generic character-sheet logic to a documentary road-film character board?
|
|
2. Can a source photo be used as identity reference without turning the output into a portrait?
|
|
3. Can the board preserve identity while keeping the character subordinate to future landscape-led composition?
|
|
4. Can the model handle a 9-cell board, or should future workflow prefer split boards?
|
|
5. Should exact labels be kept out of image generation and handled later?
|
|
|
|
## Gated Next Step
|
|
|
|
After this brief is approved, create:
|
|
|
|
```text
|
|
visual-system/characters/character-anchor-prompt-v1.md
|
|
```
|
|
|
|
That prompt document must:
|
|
|
|
- run and record the `gpt-image-2` mode check;
|
|
- read and record the relevant Skill template/reference files;
|
|
- include this brief as a source;
|
|
- include the source photo as an explicit identity reference if readable and approved;
|
|
- separate image-model output from text annotation responsibilities;
|
|
- wait for user approval before generation.
