# Input material filenames

Episode 6 did not begin with images or videos supplied by the creator. It began with one sentence, and the AI agent produced the trial materials. This page separates user input from AI-produced internal files and publishes only safe filenames and roles.

## Material provided at the start

| Filename | Role |
|---|---|
| `企画原文.txt` | Records the original one-sentence request for Aha videos featuring Japanese landmarks, cute cats, and cute dogs |

No image, video, audio, or storyboard was supplied at the start.

## Internal files produced by the AI for each work

| Filename | Role |
|---|---|
| `before.png` | Image before the gradual change begins |
| `after.png` | Image after the change is complete, preserving the source dimensions and composition |
| `answer.png` | Before-and-after comparison identifying the changed area |
| `aha.mp4` | 22-second challenge: two-second hold, 18-second change, two-second hold |
| `with_answer.mp4` | 26-second version with the four-second answer comparison appended |
| `contact_sheet.jpg` | Intermediate frames used to confirm that only the intended area changes |
| `inspection.json` | Duration, resolution, frame-rate, decode, and audio-stream inspection results |

These names have the same role inside each work folder. The actual files are not published.

## Representative examples referenced by the making-of

| Work or record | Role and result |
|---|---|
| `Mount Fuji and Its Reflection` | Accepted work used as the opening challenge; its before, after, answer, video, and inspection records are complete |
| `Retriever’s Ball` | Rejected because the change from a ball to an apple was too obvious |
| `Two Balloons over Meteora` | Passed technical checks but was rejected because the change was too obvious |
| `Whale Shark and Jellyfish` | Rejected because the change was too small to understand clearly even after the answer |
| `Sleeping Corgi and Cat` | Technical failure in which the corgi’s ear doubled at the midpoint |
| `batch_002.json` through `batch_009.json` | Evaluation records separating OK, NG, explicit reasons, and later corrections |
| `検査記録.json` | Technical inspection and identification record for the ten works in Batch 9 |

## How the files were handled

- The after image was created as a reference-based edit of the before image.
- Pixels outside the permitted change area were locked to the original image throughout the video.
- The 22-second challenge and 26-second answer version were stored separately.
- Passing technical checks and receiving human acceptance were stored as different states.
- No rejection reason was added unless the user stated it.

## Publication scope

The before-and-after images, internal change-region data, videos, answer images, contact sheets, evaluation JSON, inspection JSON, production code, and original workspace are not published. Only filenames and roles are described here.

When creating a new work, do not reuse these files. Use subject matter and materials that you have the right to use.
