Lumetro

One black phone floats in front of a night-city photograph, thin white type beside it, a blue streak on the glass, a new pose on every crossfade.

A huge dimmed night-city photograph as the whole backdrop, cool and nocturnal, with flat uppercase type and an anamorphic light streak beneath each title and across the object. Eight beats over 60 s at about 114 bpm, each around 8 s and joined by crossfades on the bar grid: tumbling entrances, tilt-downs and raking planes, bookended by a held opening and a fade to darkness.

    REF-MA-18 · CITY BACKDROP — Lumetro, a city-guide and transit app.
    A shot-for-shot remake of Motion Array "App Promo" (MambaTV, 38650): one black phone floating in
    front of a huge night-city PHOTO dimmed to indigo, thin white uppercase type set beside it as
    flat layers, and a blue anamorphic light streak on the phone's bottom edge / under each title.
    Shot sheet: reference-shot-sheet.md (same folder).

    Clock (gap-clock=run, 0.4 s plain crossfades — `crossfade` keeps each scene on its own lens; `match` would morph the camera — cuts on a 114.3 bpm 4-bar grid = 8.4 s):
      s1-logo   0.0 →  2.1   logo card
      s2-meet   2.1 → 10.5   phone tumbles in, centred; title left, copy right
      s3-depart 10.5 → 18.9  big phone left, the camera tilts down it; title + copy right
      s4-route  18.9 → 27.3  phone tumbles in to LANDSCAPE, small, centred; title above, copy below
      s5-nearby 27.3 → 35.7  big phone left in a raking plane, copy in the same plane
      s6-ride   35.7 → 44.1  phone right in a raking plane, copy left
      s7-city   44.1 → 52.5  phone turns from its back, then rolls to landscape over the skyline
      s8-end    52.5 → 60.0  logo card, fade to black
    Each scene's local 0 is the start of its incoming crossfade.

    Type: flat `text` layers in Manrope (the reference sets flat AE layers in Montserrat; flat text
    keeps them flat, as the reference does). The only text3d is the logo glyph.
    Units: mm. fov 30 everywhere: visible height = 0.536 × distance.
