ReelStack

Premium 9:16 Reel OS for Remotion. 5 cinematic style families. 22 production-tested presets. Audio-locked motion. IG-safe by default.

ReelStack is the toolkit behind the Devini Labs reel aesthetic — packaged as a Claude Code skill plus a companion CLI. One slash command (/reelstack-glass, /reelstack-paper, /reelstack-dark, /reelstack-warm, /reelstack-forbidden) scaffolds a new 9:16 reel with the right palette, primitives, motion vocabulary, BEAT skeleton, and IG safe zones already wired up. From init to first preview render in under 10 minutes.

What you get

| Family | Vibe | Presets | |---|---|---| | Glass Iridescent | Light lavender-cream + iridescent particles. Caustic blobs, sonar rings, glass cards, floating glyphs. | graphify · paperclip · gstack · lilagents · jcode · claudewatch · claudewatchcta | | Cream Paper | Warm editorial paper + dark-green cards + Claude terracotta. | justdrop · opus · designreel · devini3d | | Dark Cinematic | Zinc void + drifting spotlights + Claude terracotta. Premium ad-film mood. | stitch · stitch2 · codedrop · claudedispatch · notebooklm · gpt55 · resourcescta · skills | | Warm Signature | Single-accent rule. Amber signature + emerald payoff + bento grid. | huashu · mempalace | | Forbidden | Cream-rose paper + ember + crimson + plasma. Desaturated, mysterious. | heretic |

Each preset carries the exact palette, BEAT structure, frame count, and motion vocabulary of a real Devini Labs reel that has shipped to YouTube and Instagram.

Why pay for it

• House-style enforcement. reelstack lint flags motion-floor violations, IG safe-zone breaches, hero-text overflow, and missing audio locks. Most boring AI-generated reel templates can't do this.
• Audio-locked everywhere. reelstack beats <vo.wav> runs whisper-cli and prints frame-accurate BEAT constants. No more eyeball-drift across 90-second clips.
• GSAP vocabulary, ported. Power4Out, expoOut, backOut — translated into Remotion interpolate() so motion language stays consistent.
• Real brand assets. reelstack icons <brand> pulls genuine SVGs from Iconify (logos:react, logos:next-js, etc.) instead of asking you to hand-draw.
• Render presets. reelstack render <id> --platform=ig ships with the right H.264, bitrate, and color flags for IG / TikTok / Shorts.

Install

# Inside an existing Remotion project — or any folder; init can bootstrap one
npx @devinilabs/reelstack init

init runs a 4-tier readiness gate (v1.2+) so its success banner is provable. After it exits 0, every /reelstack-* command works — or it exits non-zero with a clear remediation.

| Tier | What it checks | If missing | |---|---|---| | 1 | Node ≥ 20 | exits with nvm / fnm / nodejs.org guidance | | 2 | ffmpeg (required) + whisper-cpp (soft, only for /reelstack-beats) | macOS+Homebrew: offers to brew install for you. Linux / Windows / macOS-without-brew: prints the exact command for your platform and exits so you can install + retry | | 3 | Remotion project + @devinilabs/reelstack dep | runs npx create-video@latest --yes --blank reelstack-project (override with --name=…, or skip with --no-bootstrap) | | 4 | Smoke test — scaffolds Demo.tsx, runs npx remotion compositions, runs ffmpeg -version | exits 1 with the failing step name. Skip with --skip-smoke. |

The verified state is recorded at ~/.reelstack/state.json so subcommands like /reelstack-beats can fail-fast with helpful messages instead of generic "not found" errors.

First reel in 5 minutes

You: /reelstack-glass
ReelStack: Which preset? (graphify | paperclip | gstack | lilagents | jcode)
You: graphify
ReelStack: Reel name?
You: MyLaunch
ReelStack: Voiceover file? (path/.wav, or skip)
You: ./public/launch-vo.wav

✓ Created src/MyLaunchReel.tsx
✓ Registered in src/Root.tsx (1080×1920, 30fps, 1956 frames)
✓ Whisper transcribed → 9 BEAT constants injected
✓ Geist fonts pre-wired
✓ IG safe zones inlined
→ Open Remotion Studio? (Y/n)

That's it. You're inside a real Devini Labs reel template, with your voiceover beats locked, your primitives imported, and Studio open at frame 0.

Requirements

| Tool | macOS | Linux | Windows | |---|---|---|---| | Node ≥ 20 | nvm install 20 / nodejs.org | same | same | | Remotion 4 | auto-bootstrapped by init, or npm create video@latest | same | same | | ffmpeg (required) | brew install ffmpeg (init can run this) | apt-get install ffmpeg · dnf install ffmpeg · pacman -S ffmpeg | choco install ffmpeg · scoop install ffmpeg | | whisper-cpp (only /reelstack-beats) | brew install whisper-cpp (init can run this) | build from source: github.com/ggerganov/whisper.cpp | build from source, or scoop install whisper.cpp | | Claude Code | claude.com/claude-code | same | same |

init's Tier 2 detects your platform and either offers an auto-install (macOS+Homebrew) or prints the exact command for your package manager — so you don't need to know the table above by heart. If you're on Linux/Windows, install + re-run init once.

Acknowledgments

ReelStack v1.1+ stands on the shoulders of two outside skills:

• leonxlnx/taste-skill (MIT) — UI design-discipline rules. ReelStack bakes the master + per-family variant overlays directly into its components, palettes, and lint. Every scaffolded reel inherits the discipline by default.
• alchaincyf/huashu-design (Personal Use Only — pattern inspiration only, no code/text copied) — productivity-UX patterns adapted to Remotion: Design Direction Advisor, 5-dim critique, multi-format render with BGM. The Warm Signature family's huashu preset is named for @AlchainHust's project.
