Showcase: it is just HTML, a developer explainer in 20 seconds

This is the one I show developers. It makes a single point, that a Second Studio video is just HTML, in five beats. The word VIDEO slams onto a green gradient. A code editor shows the markup for that word, and handwritten notes appear beside it: "the video", "shows up at 1.4s, gone 0.95s later", "your agent can write this". A small preview renders the frame next to the code. Then the word glows neon, dissolves into particles, and an end card says "It's just HTML."

How we made it

Each beat is a section of one HTML page on a timeline. The slam is a scale and blur on a heavy sans serif. The editor is real markup with syntax colors, and the annotations are drawn as strokes on a canvas so they look written rather than typed. The neon is layered text shadows. The particle word samples the letter shapes into a few thousand points and lets them drift. There is no voice, just a music bed, because the text does the talking.

It runs on our own renderer, which loads the page, steps the clock and captures every frame, so the motion is identical each time.

How your agent can make one

The public API does not accept raw HTML compositions yet. Today the closest route is an explainer with short title scenes and a code screenshot as an image scene:

POST /v1/explainers
{
  "brandId": "<your brand kit>",
  "aspect": "16:9",
  "script": { "title": "It's just HTML", "scenes": [
    { "id": "s1", "type": "title", "durationSec": 3, "headline": "VIDEO" },
    { "id": "s2", "type": "image", "durationSec": 6, "headline": "Every frame is markup", "imageAssetId": "<code screenshot>" },
    { "id": "s3", "type": "cta", "durationSec": 4, "headline": "It's just HTML.", "action": "Get started" }
  ] }
}

The screenshot goes in your brand kit's images first, since only kit images can appear in a video.

If writing your own compositions is what you want, tell us. It is the most requested thing from developers.
