Every era has a tool.
Then it has a partner.
A beat-synced motion-graphics intro film for NewEra AI Agent, cut frame-accurately to Life Force by ptasinski and RJ Pasin. Every cut is triggered by a measured onset in the track, not by a round number.
media/newera-intro.mp4 is committed
and this page plays it.
The film, section by section
Section boundaries are proportional anchors; the exact cut frame inside each
boundary comes from the measured onset list in analysis/beat_map.json.
Measured audio

Produced by tools/analyze_audio.py on the render VM. The same file the
renderer reads, so the film cannot drift out of sync with the music.
Build
Measured
Decode, STFT, onset detection, tempo autocorrelation and structural segmentation produce a per-frame energy map.
Authored
scenes/scenes.json holds seven proportional sections. No timing is hardcoded in the renderer.
Rendered
Deterministic PIL frames at 1920x1080, encoded to H.264 plus a VP9 web fallback, with synthesised sound design mixed under the track.
