# Lab 6: collect

## The context

A student in AICODE, a university course on programming with coding agents, made a short
explainer video with a coding agent during a two-hour lab. They wrote the script with the agent,
usually in `SCRIPT.md`, built the animation one scene at a time (often with Remotion or an
HTML page), and committed each iteration. They upload what you produce, and the lab instructor
plays the video at the end of the lab.

## The rules

- **Be quick:** about three minutes.
- **Ask nothing.** The student may be away. Where you cannot tell, write "unknown".
- **Change nothing in the project.** No edits, no commits, no installs, no renders. Write only
  into `lab06-upload/` in the repository root.
- **One command per call:** no `;`, `&&`, pipes or shell variables, so no call stops to ask for
  permission.

## 1. The video

Find the newest video file in the project (`.mp4`, `.mov`, `.webm`, `.mkv`), skipping
`node_modules/`, `.venv/` and `lab06-upload/`. Run `mkdir -p lab06-upload`, then compress the
video once:

```sh
ffmpeg -y -i <video> -vf "scale=-2:'min(720,ih)'" -c:v libx264 -preset veryfast -crf 28 -c:a aac -b:a 96k -movflags +faststart lab06-upload/lab06-video.mp4
```

If `ffmpeg` is not installed, use `npx remotion ffmpeg` with the same arguments. If there is no
video, say so in the log and go on: the rest still counts.

## 2. The source

```sh
git archive --format=zip -o lab06-upload/source.zip HEAD
```

It holds the committed files only. Run `git status --short` and note uncommitted work in the log.

## 3. The iteration log

Read `git log --reverse --format='%h %ad %s' --date=format:%H:%M --stat` and write
`lab06-upload/ITERATIONS.md`:

```markdown
# Lab 6 iterations

- Agent and model: <what built the video: the `"model"` values in this project's sessions in
  `~/.claude/projects/` or `~/.codex/sessions/`, if you find them in a minute; otherwise unknown>
- Stack: <e.g. Remotion + Kokoro>
- Video: <file>, <duration> s, <size before> → <size after> (or: no video)
- Commits: <N>, from <first time> to <last time>; median <M> minutes between commits
- First visual: <time and hash of the first commit with code that draws something>
- Uncommitted work: <none, or what `git status` shows>

| Time | Commit | What changed | Minutes since the last |
|---|---|---|---|
```

One row per commit, from its message and the files it touched.

## 4. Pack

```sh
python3 -m zipfile -c lab06-upload/lab06-bundle.zip lab06-upload/source.zip lab06-upload/ITERATIONS.md SCRIPT.md
```

If there is no `SCRIPT.md`, put in the file that holds the script, or leave it out. Then tell the
student, in two lines, which two files to upload (`lab06-upload/lab06-video.mp4` and
`lab06-upload/lab06-bundle.zip`) and their sizes.
