Demo: Measured Blue 《量出來的藍》 (39.5 s) · microscope.mp4 · source in demo/

One continuous camera takes a stained slice of human liver from the glass slide in the hand down to a single nucleus and back. On the way it counts the blue (collagen) inside two 1 mm circles 1.4 mm apart: 13.5 % and 32.6 %. Chinese on screen, English narration, bilingual subtitles (Chinese line above, English line below). One public whole-slide scan (Ventana-1.bif, PathAI, CC0); every number is measured from the file and listed with its method in demo/FACTS.md. The film describes measurements only; it makes no diagnosis.

Story & structure

Logline: one stained slice the size of a fingernail; the same stain, two circles 1.4 mm apart, 13.5 % blue against 32.6 %, every number counted from the scan itself.

Arc: the object (the slide on a graphite bench, its label, a fleck of tissue: one glass slide, one slice of human liver) → the size (a dive to the tissue, a dimension line, 4.80 mm) → the first count (circle A inside a large nodule, a scan front lights every counted pixel, 13.5 %) → the second count (a truck 1.4 mm to circle B, a small nodule walled by thick septa, 32.6 %) → the turn (silence, then both circles framed and held: 2.4 times the blue) → the smallest scale (a dive to one hepatocyte nucleus, a focal sweep, a ring, 8.5 µm) → the climb back to the glass, the title written on it.

Native moves spent: the dive as the signature shot (twice: slide → tissue → nodule, and nodule → nucleus), counting the colour for both circles, two circles, one verdict at the turn, the focal sweep and the ring at the nucleus, the climb back into the end card.

Shots

One continuous take; the camera is a similarity transform interpolated as a log spiral between keys. Times in seconds; magnification changes happen where the pyramid level on screen actually changes (4.04, 4.56, 9.94, 10.42, 21.02, 27.52, 27.94, 28.22 going in; six between 33.53 and 34.46 coming out).

# Time Shot Camera Native move / note
1 0.0–2.67 the whole slide across a graphite bench, label end on the right; a fleck of tissue labelled 一片人肝組織 / 三色染色 rack focus in 0–0.95, light pool drifting; 68 → 63.5 mm field, roll 90° the scanner's own photo of the slide, cleaned, logo filled
2 2.67–5.33 slide → tissue dive ×7, roll 90° → 25° (the tissue's long axis comes level); turret clicks at 1.25× and 2.5× the cover glass turns to clean glass below 30 mm
3 5.33–9.33 the tissue, a dimension line grows from its centre: 4.80 mm, 人肝組織 · 三色染色 creep 9.2 → 8.55 mm first reading
4 9.33–10.67 tissue → nodule A dive ×3.2 to 2.7 mm, roll to 18.5° (A–B line level); clicks 5×, 10×
5 10.67–15.33 circle A drawn as an arc with ticks (A · 直徑 1 mm); 11.0–12.47 a mint scan front crosses it, every counted collagen pixel lights behind it, the reading rolls to 13.5 % and springs at 12.67; raw counts below locked, creep counting the colour
6 15.33–16.67 the septa slide past truck 1.41 mm at 10×
7 16.67–20.67 circle B, the same count: 32.6 %, lands 18.0 locked, creep
8 20.67–26.67 both circles and both readings in frame from 21.67; silence 21.8–22.67; the verdict panel: B 的藍色佔比是 A 的 2.4 倍 / 相隔 1.41 mm · 同一切片 · 同一染色 pull back to 3.95 mm (click back to 5×), creep each reading held ≥ 2.5 s before the verdict
9 26.67–29.33 nodule B → one nucleus dive ×11, roll to 34°; clicks 10×, 20×, 40× the counted pixels fade on the way down
10 29.33–32.67 the frame softens, a focal plane sweeps left → right; a mint ring is drawn round one nucleus with caliper ticks, panel 肝細胞核 · 8.5 µm · 核膜外緣擬合 creep 345 → 318 µm the focal sweep and the ring
11 32.67–35.33 silence 32.3–32.67, then the climb: the scale bar jumps back 20 µm → 5 mm, six quick clicks pull ×145, roll 34° → 96° the climb back
12 35.33–39.5 the glass fills the frame, the slide's edge and a dark sliver of bench at the bottom; title written on the glass slow drift end card

Score structure

90 BPM, 4/4, one chord per bar: Dsus2 – Bm7 – Gmaj7 – Asus4 (twice), Bm under the verdict, Gmaj7, Em9 for the dive, D major when the nucleus lands, Gmaj7 for the climb, Dsus2 – D for the card. Every designed hit sits on the grid (demo/tools/cuecheck.py: 0 ms); turret clicks are foley on the picture's level changes.

Section Time Palette Notes
Open 0–2.67 bowed vibraphone pad, soft vibraphone arpeggio, long pulse bass, a high glass shimmer under the moving light, soft timpani
Push 2.67–5.33 hard-mallet vibraphone in 16ths, pulse bass in 8ths, riser turret click + servo at each level
Tissue 5.33–9.33 pad, quarter-note pulse pen on glass for the dimension line
Measure 9.33–20.67 vibraphone in 8ths, marimba off-beat ticks, quarter pulse per circle: pen for the arc, a band-passed scan moving left → right with counter ticks that speed up; glockenspiel + timpani when the reading lands (A 12.67, B 18.0); whoosh for the truck
Silence 1 21.8–22.67 room tone only
Verdict 22.67 timpani + gran cassa + glockenspiel B5 + low B in the bass first sound after the silence
Dive 26.67–29.33 16ths again, riser, three clicks
Land 29.33–32.3 water-glass motif D5–A4–F♯5–E5–D5 with echoes, D major pad, filtered sweep across the stereo field with the focal plane, glockenspiel F♯6 when the reading lands the only resolution in the film
Silence 2 32.3–32.67 room tone
Climb 32.67–35.33 a long whoosh, six lighter clicks
Card 35.33–39.5 reversed swell into a soft bass drum and bowed cymbal, the glass motif once more, slower; low D

Mix (in mix.py): stems set against the voice by active RMS (music −11 dB, pulse −14, foley −12, hits −6, room −30), music ducked ~4 dB under speech, gentle bus compression on music, pulse, foley and room only; a 38 Hz high-pass and a −4 dB shelf below 62 Hz on everything but the voice. The film measures −14.0 LUFS, LRA 5.8 LU, peak −1.8 dBFS.

End card

The camera climbs back until the glass fills the frame; on its empty cover glass, in ink: 量出來的藍 (Noto Serif SC 600), Measured Blue, a rule drawn left to right, MICROSCOPE STORY · 顯微敘事, LemoLab × Claude Opus 5.5, 數據：Ventana-1 · PathAI · CC0; the tissue fleck sits to the right. 4.2 s. The "LemoLab × Claude Opus 5.5" sign-off belongs to this library's demo only; a user's film carries no LemoLab credit and no copy of this card.
