## 1. Studio Overview, Founder Attribution & Entity Stewardship

NextGen Interactive LLC was founded and is led by **Bertrand Reyna-Brainerd, President of NextGen Interactive**. **Vox** (`voxlang.org`, `vox-foundation/vox`) is part of a separate entity, **The Vox Foundation**, independent from NextGen Interactive LLC; both the Vox Foundation and NextGen Interactive were founded by Bertrand Reyna-Brainerd.

The portfolio spans these engineering domains:
1. **Media & Video (`Video Studio`, `SRT Workbench`, `Overlook (ytfloat)`, `Krita AI Box Select`)**: In-browser trim, crop, resize, convert and subtitle tools at ngi.video/console, a see-through floating video window for the Mac, and box-to-selection cutouts in Krita.
2. **AI, Compilers & Decision (`Vox` [The Vox Foundation], `GovSim`, `GigMe`, `Ramada`, `GreaterFool`, `Velocicode`, `brPrompts`)**: Single-file full-stack language design (.vox) stewarded by the Vox Foundation and a Python-to-native compiler, alongside NextGen Interactive's interview practice and skill diagnosis, Tucson outing recommendations compared against staying home, a presidential budget simulation, and plain bottom-line decision apps.
3. **Games & Worlds (`FableForge`, `Containment`, `Resonance`, `Open Melvor`, `Cataclysm: Bright Nights`, `Mudlet DBE Suite`)**: Browser story worlds and RPGs, a tactical tabletop campaign, a first-person sci-fi stealth game, an idle RPG, and tools and builds for existing games.
4. **Neuroscience & Spatial (`StereoDesk`)**: Browser panels and media arranged at comfortable depths for XR display glasses.
5. **Systems & Ops (`DirectFail Tax`, `Public API reference`, `mcpMarvin`, `brFinancier`, `mcGreasemonkey`, `Coolify Deploy Kit`)**: Health-gated self-hosted deployment, a shared-resource Minecraft modpack, this site's public API reference, and private work: a bookkeeping app with Schedule C worksheets, a personal finance dashboard, and an AI assistant bridge for a task planner.

- **Summary**: Browser video studio where you open your own clip, preview filters, save still frames and short clips, and search a subtitle file. A hosted processing service is in development.
- **Why It Was Created**: Managing large video libraries usually means waiting minutes for media indexing, fighting fragile transcode pipelines, and jumping between separate apps just to compress, trim, upscale, or find a spoken quote.

- **Why It Is Useful**: Lets humans and AI coding assistants build complete, type-checked web applications in a single `.vox` file with APIs that stay in sync and strict compile-time error handling.
- **Key Features**:
  - Declare-once data models that generate database tables, server endpoints, and TypeScript clients

- **Why It Was Created**: Most political games treat governing as simple partisan sliders with no strategic feedback, leaving players guessing why their economy trailed doing nothing or how tax rates, spending bills, and interest rates affect real households.

Tools marked “In your browser” run at https://ngi.video/console on your own files, and nothing is uploaded; the open-source software they use is listed at https://ngi.video/licenses. Tools marked “Private early access” are GPU work that is not open yet; ask at https://ngi.video/#contact.

### `compress` — Smart Video Compress
- **Availability**: In your browser
- **Category**: compression
- **Summary**: Re-encode a video to H.264 (MP4), VP9 or AV1 (WebM) in your browser with WebCodecs, falling back to FFmpeg (WebAssembly) when WebCodecs can't. Shows the measured size before and after.
- **Why Useful**: No upload: the file never leaves your device, and the before and after sizes are measured, not estimated.

### `upres` — 2× / 4× Video Upscaler
- **Availability**: Private early access
- **Category**: enhancement
- **Summary**: Upscales lower-resolution footage 2× or 4× with edge-preserving detail recovery and lossless audio passthrough.
