Showcase: a vertical five step tutorial on a 3D diorama

"How to make a launch video" in five steps, made in the format that does well on short form: big title up top, a cute 3D scene in the middle, numbered steps, a progress bar and yellow keyword captions that follow the voice word by word. It ends on "save this for later", because that is how these videos work.

The narration explains the product while showing it: "Step one. The brief. Your agent writes what the video should say. Step two. The call. It hits Second Studio through our API, or straight from MCP." Then the voice, the captions and the render.

How we made it

1. We wrote the voiceover first and generated it with a stock studio voice. The word timings that come back drive everything else.
2. The diorama, a small white robot next to a film reel target on a round platform, is a single generated image. It is not a live 3D scene. We give it a slow push in so it never feels static.
3. Each step adds a pill with its number, a label above the robot ("brief.md", "POST /v1/videos", "voice: theo"), a dot in the step tracker and a little flash and whoosh. A bar fills as the steps go by.
4. Captions are timed to the spoken words, with the key words in yellow.

What it does not have is real animation of the objects. If you need the robot to move, that is a generated video shot, which is priced separately.

How your agent can make one

This is close to a stock vertical explainer. Ask for steps and turn captions and voice on:

POST /v1/explainers
{
  "brandId": "<your brand kit>",
  "aspect": "9:16",
  "captions": true,
  "voiceover": true,
  "brief": "30 second vertical tutorial: how to make a launch video in five steps. Brief, call, voice, captions, render. End with: save this for later."
}

For the diorama look, generate the image first and pass it as an image scene or background. Add it to your brand kit's images so the writer can place it:

POST /v1/images
{ "kind": "scene", "aspect": "9:16", "brief": "small white toy robot on a round white platform next to a wooden film reel, soft studio light, teal background, 3D render" }
