# Overview


# Second Studio

Second Studio is a video production backend for AI agents. Give it a video whose editing you like and
your own raw clips, and it returns a finished, captioned, beat-synced edit in that style — then posts
it to your social accounts when you approve. Everything works through one API key, over a REST API or
the Model Context Protocol (MCP), so Claude, Cursor or any agent can drive it.

## What it does

| Capability | What you get |
|---|---|
| **Style analysis** | A reusable *style* from any reference video: shot lengths, pacing, where cuts land on the beat, each shot's job (hook, demo, payoff…), caption look, hook technique. |
| **Style replication** | Your own clips cut to that style: matched to the reference's shots, cuts snapped to your music, captions in the reference's look, rendered and quality-checked. |
| **Generation** | Character sheets, characters, locations, props, scenes, video shots and voiceover — each directed by the studio's production skills, so you write a brief, not a prompt. |
| **Swaps and edits** | Put a stored character into an existing clip (object swap, motion transfer) or into a real photo (masked edit), keeping everything else as shot. |
| **Explainer videos** | Save a brand kit (logo, colors, font, product screenshots), get an editable scene-by-scene script from a brief, render a branded explainer in 16:9, 9:16 or 1:1 — with captions, narration and music. See [Explainer videos](explainers.html). |
| **Product recording** | Real recordings of a public web app, driven by simple steps (click, type, scroll), with a visible cursor. |
| **Video fetching** | Bring a reference in from a social URL — on your own machine through the local MCP server, or on ours where enabled. |
| **Team** | Several people on one account, each with their own key and role (admin, creator, reviewer); a shared library of brand kits, characters, styles and videos; per-person credit caps. See [Team](team.html). |
| **Posting** | Publish or schedule finished videos to TikTok, Instagram, YouTube, LinkedIn, Facebook, X and more, through accounts you connect yourself. Drafts wait for human approval. |

## How it works

```
reference video ──► analyze_style ──► style (numbers + descriptions, no pixels)
                                          │
your raw clips + music ──────────────► create_edit ──► finished mp4 (QA-checked)
                                                            │
                                                     create_post ──► approve ──► social accounts
```

- **Measured, then interpreted.** Cut points, shot lengths, motion, tempo and loudness are measured
  from the video itself. A vision model then labels what each shot is *for* and describes the caption
  style. A model never decides where a cut goes; it only describes cuts that were measured.
- **Only your footage in your edit.** A style keeps numbers and descriptions from the reference — never
  its pixels or audio. The finished video contains only the clips and music you uploaded.
- **Real interfaces only.** Recordings are of the real product. Second Studio never generates or fakes
  product UI.
- **Every render is checked** for the wrong length, black or frozen stretches, and missing or clipped
  audio before it is returned.
