*Video optimization

## Video should add context, not destroy performance.

We handle video as performance infrastructure: correct format, controlled weight, proper poster, smart loading, and reduced mobile impact.

### Video compression

Reduce video weight with settings that match the real context of the page.

### Posters and first frames

Use lightweight cover images to avoid blank spaces, layout shifts, and heavy above-the-fold loading.

### Lazy loading

Delay secondary videos so the first visit remains fast and focused.

### Mobile performance

Tune resolution, bitrate, and behavior for mobile networks and lower-powered devices.

### Core Web Vitals

Reduce impact on LCP, CLS, and perceived loading time.

### Clean integration

Prepare delivery for websites, landing pages, and Shopify stores without unnecessary apps. Intent-based loading

## Zero video bytes before play.

The poster explains the context immediately. Video enters the network only when someone intends to watch it. Poster ready **Load video** 0 KB · until intent*

**Request authorised.** Poster → metadata → video segments.

Weight

## Lighter video, without losing Quality.

The right compression, codec and poster reduce the weight delivered to the browser.
