yuv-video-director

name: yuv-video-director description: > Yuval's all-in-one AI video pipeline. Turns an idea/script into a finished, on-brand MP4 by orchestrating HyperFrames (HTML→deterministic video render), Lottie (branded motion graphics), ManimCE (math / neural-network / concept animations), and a transcribe→approve caption flow — all wrapped in the YUV.AI Neon Phoenix brand via a frame.md. Use whenever Yuval wants to make, edit, or explain something as a video: promo, explainer, launch, social reel, "make a video about X", "explain X as a video", "neural network animation", "turn this into a video", captioned tutorial, 16:9 or 9:16. Triggers: video, explainer, promo, reel, manim, lottie, hyperframes, animation, "make a video", "explain ... as a video", מצגת וידאו, סרטון, הסבר וידאו. Routes each beat to the right engine, wraps in brand, self-verifies, and renders.

The conductor for YUV.AI video. You (the agent) decide what each beat needs, route it to the right engine, compose everything into one HyperFrames composition, wrap it in the YUV.AI Neon Phoenix brand, self-verify, and render to MP4. This skill is the router + the working reference implementations; load a reference file only when that engine is in play.

Design source of truth: the yuv-design-system skill (Neon mode — pink #FF1464, cyan #00E5FF, rich-black/white, Anton+Inter+JetBrains Mono, neural-net phoenix motif). The video form of it is frame.md — see references/frame-md.md. Bundled template: assets/FRAME.md. Drop it in the project root; HyperFrames reads it.

The one law (decides everything)

HyperFrames renders by seeking each frame in headless Chrome → FFmpeg (frameIndex = floor(t·fps), same input → same output). So every visual is one of two kinds:

Pattern	Runs…	Engines	Rule
Live seekable adapter	inside the render, driven to time `t` per frame	GSAP, Lottie (`window.__hfLottie`), Three.js, a canvas driven by a GSAP proxy `onUpdate`	must be clock-driven — no `Date.now()`, `Math.random()` (seed a mulberry32), `setTimeout`, or `.play()`
Pre-rendered asset	offline, outputs a file, imported as a clip	ManimCE (Python→MP4/alpha), TTS audio, background-removal	render first, then drop in as a `<video>`/asset clip

If it can be seeked, it's an adapter. If it can't, pre-render it. Manim is always a pre-rendered clip — it has its own renderer and runs in Python; it can never be a live adapter.

Route each beat to an engine

"explain X as a TEASER/promo (FOMO, cliffhanger, fast)"              → references/teaser-explainer.md (the formula)
"explain a concept / math / neural network / algorithm / training"  → ManimCE   (pre-rendered clip — cut into BURSTS for teasers)
"branded motion: logo sting · stat reveal · icon pop · pulse"        → Lottie    (live, lottie-web)
"kinetic captions · titles · reveals · transitions · data callouts"  → GSAP      (live)  ← default
"3D / spatial"                                                       → Three.js  (live)   (Babylon NOT used)
speech → captions                                                    → transcribe + approve webapp (see video-edit skill)
no voiceover provided                                                → TTS (Kokoro: npx hyperframes tts)
brand colors / fonts / motifs                                        → frame.md  (picked up front)

GSAP is the reliable default for text/motion. Reach for Lottie for designed branded graphics, Manim for explaining an idea.

Workflow

Plan the beats. Narrative arc + which engine each beat needs. Pick 16:9 and/or 9:16.
Set the brand. Ensure FRAME.md is in the project root (copy assets/FRAME.md). All colors/fonts/motifs come from it — never invent. Three brand must-haves on every video (see references/brand-kit.md + references/cinematic.md): the real phoenix logo (assets/logo-phoenix.png) at the reveal + end card, a real featured Lottie (generate one — assets/lottie-burst-generator.py), and the link end-card (logo + "LET'S FLY HIGH" + the full link set + CTA). For teaser/social pacing see references/editing.md; for psychological/cliffhanger/FOMO cuts see references/cinematic.md.
Pre-render the asset beats first (so they exist as clips):
- Manim → references/manim.md + assets/manim-scene-template.py. Render py -m manim render -qh --fps 30 scene.py SceneName, copy the MP4 into assets/.
- Captions/TTS → reuse the video-edit skill (transcribe → approve webapp → sync) and npx hyperframes tts.
Scaffold + compose. npx hyperframes init <slug> --non-interactive. Author index.html (the hyperframes skill is the contract). Use:
- the seekable neural-net field background → assets/neural-net-field.js
- Lottie the brand way → references/lottie.md + assets/neural-pulse.json
- the Manim render as a <video class="clip" muted playsinline> body clip
- GSAP entrances per scene, a neon flash transition on each boundary, fade-out only on the final scene
- for teaser / social pacing (fast hard cuts, kinetic word-slams, a hook montage, glitch/chromatic stabs) → references/editing.md — cut it like a producer, not a slideshow
Self-verify (gates). references/gates.md: npx hyperframes lint (0 errors) → validate (0 console errors, WCAG AA) → render → spot-check 5 frames across the timeline. Fix → re-run. Lottie MUST be screenshot-verified (the Skottie-vs-lottie-web trap).
Render. npx hyperframes render --fps 30 --output renders/<name>_FINAL.mp4. For vertical, clone with a 1080×1920 layout (see video-edit).

Prerequisites (check first; degrade gracefully)

See references/prereqs.md. Need Node 22+, FFmpeg, Python 3.11+ with pip (Manim/captions). On this machine: real Python is py → C:\Python313 (the bare python is Hermes' venv with NO pip — don't use it). ManimCE installs via py -m pip install manim (no LaTeX needed if you author with Text()/MarkupText, not Tex/MathTex). If Manim isn't available → skip math beats or offer to install; never hard-fail the whole video.
