13At a timestamp:
14 
15```bash
16bash scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg
17```
18 
19At a zero-based frame index:

25## Notes
26 
27- Prefer `--time` for "what is happening around here?".
28- Use a `.jpg` for quick share; use `.png` for crisp UI frames.
29- `--index` accepts a non-negative integer only.
30- The script never overwrites an existing output. Choose a new path or remove the
31  old file only after the user explicitly asks to replace it.
