Rainbow Dragon (Forge)

On-set live grading + DIT toolkit. Grades live in the camera over IP — no LUT box required — plus verified offload, ASC MHL, clip logging, and proxy generation. Sister product to dragonflight.

What it does

  • In-camera live grading over IP
    • ARRI ALEXA 35 / Mini LF — CAP protocol (binary TCP :5055): native ASC CDL push, 3D LUT (experimental), EVENT-driven metadata
    • RED DSMC3 (Komodo/Raptor) — RCP2 (WebSocket :9998): native CDL via per-channel params
    • Sony VENICE 2 — monitoring-only (protocol closed; grade via SDI chain)
  • Node-based grade engine — input transform (LogC4 / Log3G10 / S-Log3 + gamuts), CDL, saturation, monotone curves, 3D LUT, output transform; flattens to camera-ready looks with CDL-split for live trim
  • Multicam — gang slots, per-camera capability-aware flattening, debounced push
  • Auto clip logging — rec events → shot records w/ camera metadata + grade snapshot
  • Deliverables — ALE, CMX3600 EDL (ASC_SOP/SAT), CDL/CCC, CUBE, CSV
  • Offload — multi-destination verified copy (xxHash64/MD5), ASC MHL v2.0 manifests (validates against official XSD), tamper detection, HTML/CSV reports
  • Proxies — ffmpeg ProRes/DNxHR/H.264, grade bake via LUT, TC/clip burn-ins, watch folders
  • Panels — Tangent Wave control mapping (Hub TIPC shim lands in macOS phase)

Status

Core engine + protocol layer complete: 200 tests, all camera drivers verified against wire-faithful simulators built from real protocol research (docs/research/). macOS app (SwiftUI + Metal preview + DeckLink + Tangent Hub) is the next phase.

CLI

forge sim                                  # run an ARRI CAP camera simulator
forge status  --host <ip> --port 5055      # connection/rec state + metadata
forge push    --host <ip> --look l.json --split-cdl
forge export  --db forge.db --day "Day 01" --format ale|edl|ccc|cube|csv --out f
forge offload <card> --to /raid --to /shuttle --report report.html
forge verify  <manifest.mhl>
forge proxy   --db forge.db --day "Day 01" --media /raid --out /proxies --burn-look

Build

Swift 6.0+, Linux or macOS:

swift build && swift test
