## Outputs For Review
|
|
|
|
| Arm | Output | Reference |
|
|
| --- | --- | --- |
|
|
| A | `../outputs/s14-anchor-board-reference-v1.png` | master character anchor board |
|
|
| B | `../outputs/s14-side-crop-reference-v1.png` | side identity crop |
|
|
|
|
## Codex Comparison
|
|
|
|
| Dimension | Arm A: master board | Arm B: side crop |
|
|
| --- | --- | --- |
|
|
| Reference evidence | Pass via visible image context | Pass via visible image context |
|
|
| Identity preservation | Strong overall identity and outfit preservation | Stronger side-face identity preservation |
|
|
| Glasses / hair / beard | Preserved | Preserved more tightly in side profile |
|
|
| Coat / backpack | Very strong | Strong |
|
|
| S-14 half-profile function | Good, but a little more three-quarter | Better match |
|
|
| Environment-led MV feel | Slightly better scene balance | Slightly more figure-dominant |
|
|
| Main risk | Less precise side-face control | Portrait-size pull from crop |
|
|
|
|
## Codex Ranking
|
|
|
|
For `S-14` specifically:
|
|
|
|
1. Preferred primary reference: side identity crop.
|
|
2. Useful supporting reference: master character anchor board, especially if the tool path supports multiple reference images.
|
|
|
|
If only one reference can be used for `S-14`, Codex recommends the side identity crop.
|
|
|
|
If multiple references can be used, Codex recommends:
|
|
|
|
```text
|
|
Primary: character-anchor-v2-side-reference-crop-tight.png
|
|
Secondary: character-anchor-v2-codex-posture-test.png
|
|
```
|
|
|
|
The side crop should control face / glasses / hair / beard / age. The master board should control coat / backpack / posture / overall character continuity.
|
|
|
|
## User Decision
|
|
|
|
The user concluded:
|
|
|
|
1. The successful channel is `gpt-image-2` Advisor prompt generation plus loading the real reference image into context before host `image_gen`.
|
|
2. This successful channel should be used now and in future; API/Garden generation should not be the default path.
|
|
3. Both the master anchor board and crop reference preserved strong character consistency.
|
|
4. Near shots should prioritize crop references; distant shots should prioritize the anchor board.
|
|
5. For `在路上`, because most shots are landscape-led, aerial, or distant and only need character consistency, crops derived from the accepted anchor board are sufficient.
|
|
6. For future projects with high identity requirements and many close shots, higher-resolution crop references may be generated through image-to-image from the accepted anchor board before production.
