# filmSound The soundtrack of *Standing Ovation*, on the film clock. It sits on the `Sound` anchor. On wake it builds the whole soundtrack under that anchor as real entities in real places — the rain in the dome, the water on the proscenium, the ballast at the worklight, the applause across the stalls and up in the balcony, the fourteen filaments down the apron — and then registers with the clock: * every frame, each bed's `gain(t)` from `sound.mix` is a pure function of film time, so the mix is the same on every playthrough and a rewind puts it back; * every one-shot is a `Film.at` cue, so it fires once, on its frame, and is re-armed by `Film.rewind()`. Everything is heard through the AudioListener on the FilmCamera, which the camera slice moves shot by shot — so the mix re-balances itself as the lens changes seats, with no automation written for it at all. ## Fields `beds`, `emitters`, `cues` — what it built. `loudest` — the bed on top right now. ## Methods ```lua local s = entity.find("Sound").component.get("filmSound") s:at(70) -- every bed's gain at that film second s:rebuild() -- rebuild every emitter and restart the beds ``` ## Putting it on the world ```lua require("camera.mount").all() ```

# filmCamera The lens of *Standing Ovation*. It sits on the `FilmCamera` entity and is the only thing that writes that entity's transform or its fov. It does not tick. It registers with the film clock in `awake()` and is called by the Director's tick, so the lens runs on the same fixed 1/24 s as everything else in the film. Every frame it reads the set-up out of `camera.shots`, evaluates the path at the shot's own `u`, and puts the lens there. **Cutting is the same act.** The shot the clock names changes on a boundary in `Film.SHOTS`, so the lens is in the new set-up on the very next frame with nothing in between — a hard cut, on the frame, thirteen times. ## Fields `shot`, `fov`, `eyeX`, `eyeY`, `eyeZ` — read-outs of where the lens is now. ## Methods ```lua entity.find("FilmCamera").component.get("filmCamera"):bookend() --> shot 13's station, aim and lens against shot 1's ``` ## Putting it on the world ```lua require("camera.mount").all() ```
