A generative, code-rendered music video for "Neon Overdrive" (mroneilovealot), styled as the NERV HQ command terminal from Evangelion: 16 plates, one HUD instrument per section, every instrument a real sound visualizer (waveform scopes, spectrum analysers, beat-grid countdowns, clap alarms). Every frame is a deterministic function of song time, so the browser preview and the offline 1080p60 / 4K60 export are identical. Built on Giacomo Magnanini's engine from the P(doom) video, by way of the Lithium video.

Concept, style bible and plate briefs: docs/TREATMENT.md. Engine and scene API: docs/ENGINE.md. The shared NERV UI kit: app/src/scenes/_eva.ts.

The song is not in this repo. Download "Neon Overdrive" by mroneilovealot for free from Pixabay. Its license covers using it in videos but not re-hosting the file. The analysis data is included (data/audio.json has beats, sections, onsets and envelopes; data/spectrum.bin has mel and chroma frames). The raw waveform data/wave.bin is not included, because it is a playable copy of the track. analyze.py rebuilds it, and the scopes stay flat until you do.

Save the track as audio/evangelion.m4a (preview) and audio/evangelion.wav (analysis and export audio), then rebuild the analysis:

mkdir -p audio
ffmpeg -i <song.mp3> -vn -c:a aac -b:a 256k audio/evangelion.m4a
ffmpeg -i audio/evangelion.m4a -ac 2 -ar 44100 audio/evangelion.wav
cd analysis
uv run python -m demucs -n htdemucs -o stems ../audio/evangelion.wav
uv run python analyze.py          # data/audio.json, spectrum.bin, wave.bin  (--bars prints the bar table)

cd app
bun install
bunx vite --port 5191             # http://localhost:5191, ?t=68 starts at 68 s

Keys: space play/pause, ←/→ ±1 s (shift ±5 s), ,/. frame step, [/] previous/next plate, l loop plate, h hide UI.
