# Browser demo video pack

Three demonstrations performed in the Codex in-app browser. No QuickTime or desktop recorder was used. All videos are silent, 1920 × 1080 H.264 MP4s.

## Files

- **01-workflow-timed.mp4** — draw a five-stage research workflow in Excalidraw, starting from a blank canvas.
- **02-shopping-timed.mp4** — search eBay, exclude auctions, inspect three Japanese Pikachu promo listings, and compare item price, delivery, and seller feedback.
- **03-kyoto-timed.mp4** — add Nishiki Market to a Kyoto walking route and inspect its Street View preview.
- **ai-research-workflow.jpg** — the finished diagram.
- **timing-manifest.json** — measured take durations and the source intervals used in the highlights.

## Timing and recording method

| Demo | Measured take |
|---|---:|
| Research workflow | 35.814 seconds |
| Shopping comparison | 98.695 seconds |
| Kyoto walk | 83.361 seconds |

These are prepared demonstration takes, not cold-start speed benchmarks. Browser setup, planning, and rehearsals are excluded. The diagram is a clean second take after correcting a label in the first attempt. The timers include the reasoning and waiting intervals within each recorded take. Each video ends with a short frozen hold on the completed result.

The available browser tool exposed screenshots, not a native video stream. These videos therefore use **actual browser viewport frames**, captured at a target cadence of one frame per 100 ms while browser-action calls are active. Between calls, the last captured frame is held while the elapsed clock advances. Output is encoded at 30 fps using repeated frames; it does not contain 30 unique captured frames per second. There is no captured tab audio or microphone audio.

The reel trims idle intervals, initial loading, and unavailable Street View steps. It does not accelerate the retained action sequences. The three timed clips preserve the full elapsed timeline with held idle frames. Browser screenshots exclude the desktop and actual app address bar; the surrounding labels and clock are editorial overlays. Personal suggestions, account imagery, and detected location text are masked.

## Shopping result and sources

Totals exclude tax and use the delivery quote shown in the browser. Prices and availability can change. The third item's detail-page price was $1 lower than the initial search result, so the comparison uses its detail-page price. Nothing was purchased, bid on, or added to a cart.

## Travel result

[Kiyomizu-dera → Yasaka Shrine → Nishiki Market](https://www.google.com/maps/dir/?api=1&origin=Kiyomizu-dera+Kyoto&destination=Nishiki+Market+Kyoto&waypoints=Yasaka+Shrine+Kyoto&travelmode=walking): Google Maps displayed **2.5 km and 34 minutes walking**, excluding time at the stops. The route is a demonstration, not a schedule or opening-hours check. Some preview steps lacked imagery; those remain visible in the timed take. The successful street-level view displayed an image-capture date of September 2025.
