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.
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.
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.
