REEL IS EMPTY

Describe a scene on the left and hit "Generate" — the first take shows up here.

ART DEPT IS FREE

Describe a shot, location or prop — the artist renders it. Your next message edits the last image, and the result goes to the library, ready to @mention in a prompt.

Prompt for the API — as sent

New character

Name — for the @mention

Appearance — mockup sheet

file or asset from the library — mockup sheet or portrait

Attached files get an invisible anti-moderation layer: previews stay clean, and the model is sent a film-grained copy that walks photoreal references past moderation. Assets picked from the library are used as they are.

…or Asset ID from the engine's library

up to 14 photos of a person — or leave empty and describe the character in text

One sheet, 21:9, 2K: full-height front · profile · back · close-up portrait. ≈ $0.03–0.13 per sheet.

Voice

One account holds your projects, cast and takes. Renders keep running on your own key — signing in doesn't change what a take costs.

Studio key pool

The studio's own keys — what bonus renders are charged to. Load is spread across the keys of a provider, and a key that is out of money or revoked leaves the rotation on its own.

Scene 01 First day on set

Your soundstage is lit.

Longtake is a cloud AI video studio built on Seedance 2.0 — cinematic shots at token cost, no middleman markup.

01
Cast with a locked voiceCharacters keep the exact same voice across every scene — no drift.
02
Series structureProject → episode → scene → takes. Organise like a real production.
03
Fix a detailPause a finished take, outline what bothers you, say what it should be.
04
Art DeptGenerate reference frames in a chat, drop them straight into shots.

One key. When you need it.

Renders run on your own BytePlus key, directly at token price — Longtake takes no cut. Stored encrypted, used only for your renders.

Video & images — BytePlus ARK How to get this key, step by step — including model activation ↗

This is the only key you need to start. BytePlus wants $30 on the account before it switches its models on — that money goes on your own renders, not to us. Voice, upscaling and the backup image engine have their own keys, and the studio asks for those where they're used.

Keep everything you shoot.

The studio itself is free — shoot on your own key, no markup, ever. A subscription is what keeps your projects from expiring.

Skills For your coding agent

Let your agent write the prompt.

Four skills holding the prompt grammar of the models this studio renders on — written from what those models actually obey, not from guesswork. Install once, then ask Claude Code or Codex for a scene in plain words.

01
Seedance 2.0Single shots and multishot sequences, up to 15 seconds.
02
Seedance 2.5Up to 30 seconds, timestamps, editing, storyboards, keyframes.
03
Gemini OmniOne continuous shot instead of a cut-up one, readable on-screen text.
04
Character sheetsCharacters, locations and props your takes can reuse.

Or download the archive and unzip it into that folder yourself. What's inside ↗

Saved. One move left.

Let the agent install it. Drag the saved archive into your Claude Code or Codex window — that drops its path in — and ask:

Prefer the terminal, and it went to your downloads?

01
Drag the file into the agent's windowClaude Code and Codex read files from your disk, so this is all the address they need. A browser chat can open the archive but cannot install it — it has no disk of yours.
02
Start a new agent sessionSkills are read when a session starts — one already open will not see them.
03
Ask in plain words“Write me a Seedance 2.5 prompt — 20 seconds, a courier on a stairwell.”
