# Motion article demonstrations

These are author-made teaching examples, not customer performance studies or captures of product features.

- `assets/loop-motion-study.mp4`: three actual six-second cycles; compare endpoint velocity as well as position.
- `assets/moving-background-study.mp4`: fixed text over a changing background, with and without a protective surface.
- `assets/audio-alignment-study.mp4` and `assets/synthetic-cue.wav`: constructed timing example with a known audible onset.
- CSV/SVG/PNG files preserve the calculation and chart outputs discussed in the articles.
- The three Python source files use Pillow, NumPy, Matplotlib as applicable, plus an installed `ffmpeg`. The included Albert Sans font is resolved locally. These portable copies change only asset/font/tool paths; the original rendered files and execution records remain preserved in the workspace.
- `encoding-study/README.md` records the actual encoding/decoding commands and limits, with the measured files and results.

The model comparison article reports only a partial real run: Codex produced a source artifact; the isolated official Claude request did not authenticate. There is no fabricated model ranking or completed two-sided playback result.
