# ovation.film The shared spine of **Standing Ovation** — a 90-second cinematic demo set in a rotting 1,412-seat theatre. Two things live here and nothing else. ## The constants The Odeon Marisol's geometry (`Film.GEO`, `Film.rakeY`, `Film.stallSeat`, `Film.balconySeat`), its palette (`Film.PALETTE`), its four light sources (`Film.LIGHTS`), its acts (`Film.ACTS`) and its shot list (`Film.SHOTS`). Every slice of the demo reads its colours and dimensions from here rather than restating them, because two slices disagreeing about where row A stands breaks the film in a way no screenshot explains. ## The film clock One deterministic timeline the whole demo runs on. It advances a **fixed 1/24 s per rendered frame** — it reads no wall time and no real frame delta, so the same build produces the same 2,160 frames on any machine, under a recorder or without one. ```lua local Film = require("ovation.film") Film.rewind() -- every reset hook fires, every cue re-arms, t = 0 Film.play() -- the Director advances it from the next rendered frame Film.on("mine", function(t, dt, shot) end) -- called every frame Film.at(47.0, "cue", function() end) -- once, as the clock crosses 47 s Film.reset("mine", function() end) -- back to the t = 0 state ``` `Film.stop()` freezes it with the frame still composed. `Film.seek(t)` lands on a moment for authoring and does not fire the cues in between. `Film.ramp`, `Film.smooth` and `Film.wave` are the shared shaping helpers: this film is made of waves crossing 1,412 identical figures. Only `ovation.director` calls `Film.tick`.
