AI judge
AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. No AI-judge score exists for this result: there is no rubric for this prompt, so no score is shown and none is made up.
Visitors
Public voting with a blind reveal is coming: you score the output first, then see the other scores.
Reviewer
The reviewer's own grade appears here once it is added.

Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.

The exact prompt

as run, 3,766 characters. Every result for this prompt

Build a HyperFrames composition titled "Artemis II: Return to the Moon" — a
cinematic 60-second explainer video (16:9, 1920x1080) visualizing NASA's
Artemis II crewed lunar flyby mission (April 1–11, 2026).
VISUAL IDENTITY
Style: "Mission Control Cinematic" — dark deep-space canvas with precision
data overlays, inspired by NASA flight dynamics consoles and cinematic
space documentaries.
- Palette: #05070D (void black), #0B1426 (deep navy), #E8EEF7 (bone white),
  #FF6B35 (ignition orange), #4FC3F7 (telemetry cyan), #FFD166 (lunar gold)
- Typography: "Space Grotesk" for titles/headings, "JetBrains Mono" for
  telemetry, coordinates, timestamps, distances
- Motion: precise, weighted easing (power3.out, expo.out). No bouncy motion.
  Data counters use tabular-nums. Subtle starfield parallax on all scenes.
SCENE BREAKDOWN (7 scenes, ~8–9s each, shader crossfade transitions)
Scene 1 — TITLE CARD (0–8s)
Hero title "ARTEMIS II" at 180px, subtitle "First Crewed Lunar Flyby in
Over 50 Years" at 36px. Mission patch silhouette fades in behind. Mono
datetime stamp bottom-left: "APR 01 2026 · 22:35 UTC · KSC LC-39B".
Scene 2 — LAUNCH & HIGH EARTH ORBIT (8–16s)
SLS rocket SVG silhouette with animated exhaust plume. Heading "PHASE 01 ·
LAUNCH + HIGH EARTH ORBIT". Ticker with live telemetry: altitude counting
up, velocity in km/s, T+ mission elapsed time. Annotation: "~24h elliptical
orbit for system checkouts".
Scene 3 — TRANS-LUNAR INJECTION (16–24s)
Animated orbital diagram: Earth (left), Moon (right), curved free-return
trajectory drawn with SVG stroke-dashoffset animation in cyan. Label
"TRANS-LUNAR INJECTION BURN · 6 MIN" with flame icon at burn point.
Stat card: "Δv: +3.05 km/s".
Scene 4 — OUTBOUND COAST (24–32s)
Orion capsule wireframe drifting across frame. Progress bar "EARTH → MOON"
filling left-to-right over 4 days. Distance counter animating from
384,000 km down to closest-approach value. Subtle earthrise reference.
Scene 5 — LUNAR FLYBY (32–42s) — HERO MOMENT
Full-frame Moon with crater texture. Trajectory arc sweeps behind the far
side. Pulsing marker labeled "CLOSEST APPROACH · APR 06 2026 · 6,545 km".
Secondary stat: "DISTANCE FROM EARTH · 406,771 KM — FARTHEST HUMANS HAVE
EVER TRAVELED". Crew name plate fades in: Wiseman · Glover · Koch · Hansen.
Scene 6 — RETURN COAST (42–50s)
Mirror of Scene 4 in reverse — trajectory arc completing the figure-8.
Heading "FREE-RETURN · GRAVITY BRINGS THEM HOME". Re-entry velocity
counter climbing toward 11 km/s.
Scene 7 — SPLASHDOWN (50–60s)
Pacific Ocean horizon at dawn, Orion under three parachutes. Final stat
block: "10 DAYS · 1 FLYBY · 4 ASTRONAUTS · ∞ AMBITION". Closing title
"APR 11 2026 · PACIFIC OCEAN · MISSION COMPLETE". Fade to black on
"NEXT: ARTEMIS III — BOOTS ON THE MOON".
TECHNICAL
- Generate a DESIGN.md before writing any HTML with the palette, typography,
  and "What NOT to Do" list (no generic blues, no Roboto, no bouncy easing,
  no full-screen linear gradients on dark backgrounds).
- Use sub-compositions for each scene (scene-1.html through scene-7.html).
- Shader crossfade transitions between scenes (~0.6s each).
- All data counters deterministic (seeded PRNG if needed, no Date.now).
- Run `npx hyperframes lint` and `npx hyperframes validate` before finalizing.

HyperFrames 0.8.70 is already installed for you in the current directory: node_modules is pre-installed and read-only, so do not run npm install or npx --yes; use the local hyperframes command (for example hyperframes init <dir> --example blank, then hyperframes render). Render the final video yourself to out.mp4 in the current directory. You may take snapshots and inspect your own output (headless chromium is available at /usr/bin/chromium) and iterate on your own before finishing.
