We build the deterministic HTML-to-video pipeline at HyperFrames. We write here when we have something concrete to say.
Build an animated app onboarding video in HTML — three-screen carousel with sliding screens, fading headlines, scaling illustrations, advancing dots — and render to MP4.
A podcast audiogram generator built in HTML: a 32-bar waveform animates with per-bar phase offsets, captions appear in sync, and the episode title sits on top.
A discount banner animation that counts up the percentage, wiggles its dashed edge, pulses urgency copy, and shimmer-strikes the original price. Built from HTML, rendered to MP4.
Build an animated funnel chart in plain HTML and CSS — stacked trapezoids, conversion percentages that count up, deterministic MP4 export. No charting library required.
Send customers a 20-second recap of their monthly invoice — top metrics, charges, savings — rendered from their data. Quietly more memorable than an email.
Both let you render video from code. The difference is in the abstraction — React components and a runtime versus plain HTML and a renderer. Here's how to pick.
VideoObject schema, WebVTT chapters, MP4 atom metadata, and the YouTube data layer — a 2026 guide to making your videos discoverable, accessible, and machine-readable.
Nondeterminism breaks the most important thing an agent has: its feedback loop. Why reproducible rendering is the missing primitive for agentic video, and what an agent-friendly render API looks like.
A field guide to the generative video models shipping in 2026 — Sora 2, Veo 3, Runway Gen-4, Pika — what they cost, what they get right, and where deterministic HTML-to-MP4 fits in a stack that uses all of them.
A walk through the actual infrastructure we use to ship ten thousand personalized video variants in a single overnight job. CI architecture, fanout, caching, and the math of variant pricing.
From a tiny JSON file to a 16:9 animated bar chart you can render to MP4. CSS, no charting library.
Two hundred particles, gravity, rotation, and a single canvas. No library, no engine, no After Effects.
A 3000×3000 podcast cover template that renders per episode. Title, number, guest, render.
A 5-second channel intro template that re-renders per episode. One HTML file, infinite variants.
One HTML template, three aspect ratios, three MP4s. The container queries that make it work.
Video formats describe pixels. HTML describes intent. When a browser can render frames deterministically, the document becomes the codec — and the entire pipeline changes.
