The film: `ebb.mp4` ## How it was made (from the composition's header) ```text CONCEPT — one take, and the light carries the camera. ebb is a focus timer (fictional); its one object is a field of warm light that lives under everything and is time made visible. The camera never cuts: it starts inside the digits, pulls out to the Mac app, rides the light up while a session runs, punches onto 00:00, and travels under the flood while it drains in rings — the rings open on the phone, whose lock screen is the break in silk. It pushes onto the Live Activity, whips down onto the day's sessions (three rows of silk at three depths, drifting against each other), dollies along them, and pulls back while they fly into the week. The week sinks into the horizon as light, and the name rises out of it. The camera is keyed (OM.camera) plus shake, parallax (OM.view depth) and a far lattice — no OM.rig, so it runs on lite. t beat camera what carries into the next beat 0.00–1.25 25:00, macro 3.6×, dead still the digits 1.25–2.10 the Mac window pull out to 1.12× (quintInOut) the window 2.20 start a tap of shake; the pill dips (.snappy), becomes the running dot 2.35–4.35 the session slow push to 1.5× with a 1.3° dutch; handheld the light odometer digits, light rising behind the glass, white where it passes; sidebar bar fills 4.35–4.95 00:00 punch to 3× on the colon (expoOut), hold the light 4.95–5.25 flood shake the light 5.25–6.75 drain → phone rings leave the colon; under them the camera travels 3× → 1× to the phone the silk 6.35–7.55 the break push to 2× on the Live Activity; break 4:59 ticks the silk 7.55–8.15 whip down onto the rows (expoInOut), landing shake the rows 8.15–9.70 the day dolly left along three rows at three depths the cards 9.70–10.75 the week pull back, rotate level; 21 cards fly to a 7 × 3 grid the grid 10.95–11.80 into the light crane down; the grid sinks column by column; the field rises the light 11.80–12.60 ebb the name drops, the line rises; belt and silk slow to a stop 12.60–15.00 rest dead still ```
