video production engine

Films that compile.

A video production engine that treats a film as source code — scenes are YAML programs, rendering is a build, and every shot ships with machine-checked proof that it is correct.

Framing, occlusion, timing, and motion — verified from the renderer's own ground truth. No human review loop. No vision-model guesswork.

Greenlight-rendered scene
01 · declare

A film is a git repo of text

Shots declare framing, staging, motion, and assertions in a closed, schema-checked vocabulary.

assert: visible(hero) >= 0.9
02 · render

The program becomes a build

The compiled scene renders through Greenlight's headless Blender bridge — the same pipeline behind every shot.

03 · verify

Every render ships with proof

Identity, depth, and occlusion passes plus per-frame motion telemetry — checked deterministically, fail-closed. $ gl verify → green

how it works

A compiler and CI system for moving pictures

gl check→ gl compile→ gl render→ gl verify→ gl finish

Declarative scenes

A film is a git repo of text. Shots declare framing, staging, motion, and assertions in a closed, schema-checked vocabulary. The canonical artifact is the program — video is a build product.

Ground-truth verification

Every render emits evidence: object-identity, depth, and occlusion passes plus per-frame motion telemetry. Assertions are checked against that evidence — deterministic math, fail-closed, no learned judges.

Agents repair, engine proves

Failures return structured diagnostics with causes and repair hints. Any AI agent — bring your own — can iterate edit → verify until green, unattended. The engine contains no LLM, so it never goes stale.

Verified renders land here as the engine ships them

Structured slots for engine output — poster frame, proof badge, and the verdict trail above, wired in the moment a render clears gl verify.
