Videos

Short revision episodes (algorithms, C++, Python, operating systems, system design, "Build it" implementation problems, and tools & frameworks) for the notes in ai-docs: one clip per question, each opening with the question and a pause to answer out loud before the explanation.

Layout

Path	What
engine/	Shared episode engine: templates, runtime, build / render / publish tools. Start with its README.
episodes/<slug>/episode.json	One spec per ai-docs note. The only file you write for a new episode.
docs/	GitHub Pages index, rendered from docs/catalog.json.
cpp-oop-walkthrough/, cpp-functional-walkthrough/	Earlier long-form videos (HyperFrames and a standalone HTML project).

Videos and posters are not stored in git: each episode is a GitHub Release (ep-<slug>), and the catalog links to its assets. npm run publish -- <slug> uploads them and updates the catalog.

Quick start

npm install
npm run build   -- algorithm-sliding-window   # narration + timings (Kokoro TTS, whisper)
npm run dev                                   # preview: /engine/player.html?ep=algorithm-sliding-window&clip=01
npm run render  -- algorithm-sliding-window
npm run publish -- algorithm-sliding-window

Requires Node.js 22, ffmpeg, whisper-cli, and a Python environment at .venv/ with kokoro-onnx.
