What it does

sound.mix

Where the sound of Standing Ovation stands in the room, and what it does over the ninety seconds. Two tables and nothing else.

Mix.BEDS

The ten sources that run the whole film and are mixed by a curve. Each carries a world point — so the AudioListener on the FilmCamera hears it from wherever the shot is standing — and a gain(t) that is a pure function of film time. No wall clock, no accumulated state, so a rewind puts the mix back exactly.

Two of them FOLLOW: Breath carries a follow(t) that walks it on with him and stands it 45 cm from the lens for shot 6, so the closest sound in the film is a moving source rather than a placed one.

Mix.SHOTS

The one-shots, each with its own emitter so it is heard from its own place: fourteen Filament** down the apron igniting one at a time across shot 4; DomeWater dripping onto the rake; RowGHands, the single pair in shot 10, clapping slowly and out of time with everything behind it; CurtainIn; Steps — an emitter that WALKS, its position read off the same Mix.walkPoint the lens composes shot 5 on, so his eight footfalls cross the stage in the room rather than arriving from one point in it; and GlovedHands — which is not in the room at all. It is at the lens.

The dramaturgy, in one paragraph

Acts I and II are rain, a room, a buzzing choke and two low strings — and no hands at all, which is what makes the first clap in shot 10 land. Shot 10 brings one pair in, out of time, with a dozen behind it at another rate. Shot 11 opens the full house. Across shot 12 the loose house is crossfaded under a gridded one, so 2,824 hands drift from chaos into unison without anything about the sound changing except which layer is loudest. Then the room empties again: shot 13 is rain, the ballast coming back up, and one pair of gloved hands close to the lens.

sound.mix — where the sound of "Standing Ovation" stands, and what it does. Two tables and nothing else. BEDS the sources that run the whole film and are mixed by a curve: rain on the dome, water down the proscenium, the room, the worklight's ballast, the score, and the three applause layers. Each carries a world point (so the AudioListener on the FilmCamera hears it from wherever the shot is standing) and a `gain(t)` that is a pure function of film time — no wall clock, no state, so a rewind puts the mix back exactly where it started. CUES the one-shots: fourteen filaments igniting down the apron, water off the dome, one pair of hands in row G, the curtain, and the gloved pair that closes the film. The dramaturgy of the mix, in one paragraph. Acts I and II are rain, a room, a buzzing choke and two low strings — and no hands at all, which is what makes the first clap in shot 10 land. Shot 10 brings ONE pair in, out of time, with a dozen behind it at another rate. Shot 11 opens the full house. Across shot 12 the loose house is crossfaded under a gridded one, so 2,824 hands drift from chaos into unison without anything about the sound changing except which layer is loudest. Then the room empties again: shot 13 is rain, the ballast coming back up, and one pair of gloved hands close to the lens.

# camera.shots The thirteen set-ups of *Standing Ovation*, as data — where the lens stands, what it is aimed at, how it moves across the shot, and which lens it is on. Consumed by `camera.filmCamera`, which evaluates it every rendered frame off the film clock and writes the FilmCamera's transform and fov. Nothing else writes that camera. ## What an entry holds | key | meaning | |-----|---------| | `eye` | world points. One = a locked-off camera. Two or more = keys the lens moves through. | | `look` | world points, the same shape. What the lens is aimed at. | | `lookRel` | an aim offset carried along with the lens, instead of `look` — a tracking shot that keeps looking the same way relative to itself. | | `lookEntity` | a leaf another slice owns. If it is in the world the aim follows it; if it is not, the aim falls back to `look`, so a shot never stops framing. | | `ease` | `"smooth"` (default) or `"linear"`. | | `breathe` | metres of deterministic drift on a locked-off lens, a pure function of the shot's own local time. A held camera, not a rendered still. | The lens is never restated here: `Shots.fov(n)` reads `Film.SHOTS[n].fov`. ## The bookend Shot 1 and shot 13 are the same station, the same aim and the same lens. They do not hold two copies of the numbers — both entries carry `Shots.STATION_I14` and `Shots.AIM_I14` **by reference**, and `Shots.check()` asserts that with `rawequal` so the two ends of the film cannot drift apart: ```lua require("camera.shots").check() --> { bookendSharesStation = true, bookendSharesAim = true, -- bookendSharesLens = true, millimetres = 0, setups = 13 } ``` ## Calls ```lua local Shots = require("camera.shots") Shots.eval(n, u) --> ex, ey, ez, lx, ly, lz -- u is 0..1 across shot n Shots.station(n) --> x, y, z -- the undrifted station Shots.fov(n) --> vertical degrees Shots.check() --> the bookend report above ``` ## Points other slices may want `Shots.STATION_I14` / `Shots.AIM_I14` (the bookend), `Shots.AISLE_LEFT` / `Shots.AISLE_RIGHT` (the two aisles cut through the stalls — the house has none on its centre line, so shot 9 tracks up the house-left one), `Shots.PERFORMER` (where shots 5, 6 and 7 compose on him: he comes on from `entryX`, arrives at `centreX`, stands at `standZ`, and his head is at `headY`), and `Shots.ROW_G_SUBJECT` (the one shot 10 watches).

# 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`.
