# The Marble Shrine — animated sigil (for video editors)

The homepage hero sigil, rendered as **white on a transparent background** so it
drops straight onto any footage.

## Files

| File | What it is | Use it in |
|---|---|---|
| `sigil-draw-spin-4k.mov` | **ProRes 4444** video, 3840×2160, 30fps, 5.5s, **real alpha channel** | Premiere, Final Cut, DaVinci Resolve, After Effects — drop it on a track above your footage; transparency just works |
| `frames/frame-####.png` | 165 transparent PNG frames (the lossless master) | Any tool; import as an image sequence at **30fps** if you don't want the .mov |

## Notes

- **One clean loop.** The clip is a single 5.5s cycle that fades in at the start
  and out at the end, so it loops seamlessly — set it to repeat for a continuous
  spin.
- **It's white.** Meant for dark/varied footage. To tint it, use your NLE's
  color/tint tools on the clip (it's a single-color mark, so a tint recolors the
  whole thing cleanly). Ask if you'd like a mid-gray or brand-color version.
- **Don't re-export to MP4/H.264 if you need the transparency** — those formats
  have no alpha. Keep it as ProRes/PNG until the final composite.
- **4K wide, sigil centred.** Scale/position freely; it's sharp well past 100%.

Regenerate with `node scripts/export-sigil-animation.mjs` (from the repo root,
after a build) if the sigil or animation ever changes.
