Audio and video

Sonic identity and video production rules.

Audio identity

Four defined cues. All are short, tonal, and mid-register — the audio equivalent of “slides into place, doesn’t bounce”.

ErrorSingle low A2300ms

Error is a single low note, not a buzz or a descending pair — it marks the event without scolding.

Video rules

  • Demos run at real time. No fast-forward, no speed ramps. If a step is slow, that is information the viewer needs.
  • Transitions are a cut or a 200ms fade. No swoops, wipes, or 3D moves.
  • All video uses midnight surfaces.
  • Subtitles are always available.
  • Export at 1080p minimum, 4K when possible.
Do

Show the real thing at real speed. Caption everything.

Don't

Speed up a demo to hide latency, or use a transition that draws attention to itself.
