Why we
built it.

Polished 3D motion shouldn’t need a heavy toolchain. Sequel Box keeps the controls familiar and the presets one click away.

Video motion shouldn’t
need a heavy toolchain.

Sequel Box is a 3D video editor for Windows and the browser. It started from a simple frustration: making a short, polished video with 3D motion usually means juggling a design tool, a video editor and an animation program, each with its own learning curve.

We wanted one place where the controls feel familiar, the results show up quickly and nothing gets in the way. So Sequel Box puts a layered timeline, click-to-add keyframes, one-click 3D presets and 72 built-in sounds in a single editor. You import your clips, images and audio, animate them, and export an MP4.

Your work stays yours. Projects save as .sbox files on your own computer, and version 1.0.0 is free to try.

What we care about

familiar tools

Simple first

Every tool is where you expect it, with a shortcut for each.

presets first

Fast to learn

Presets give you results before you learn keyframes.

local files

Yours to keep

Projects save as .sbox files on your computer.

Who Sequel Box is for

Who it’s for.

If you want motion without a steep learning curve, Sequel Box is built for you.

designers

Bring designs to life

Copy layers in Figma, press Ctrl+V in Sequel Box, and every layer lands on its own track, ready to turn and animate. See Figma to video.

social creators

Make it fit every feed

Start from a canvas for Instagram, TikTok, Reels, Shorts, YouTube, Pinterest or X, and use the safe-zone overlay so captions never hide under the app’s buttons.

AI-agent users

Describe it, get the video

Connect Claude, Cursor or any MCP-compatible agent to the desktop app and describe what you want. It builds the project and exports the MP4. How to connect.

What we believe.

Fewer steps, faster results

Presets give you a finished-looking move before you ever learn keyframes, and when you do want control, click-to-add keyframes mean you never drag the playhead.

Your files stay on your computer

Projects are saved locally as .sbox files, and when an AI agent builds a video through the desktop app, everything stays on your computer.

Works where you work

Install the Windows app, run the portable file from any folder, or open the editor in Chrome, Edge or Safari. See downloads.

Honest and open to feedback

Sequel Box is young, and we say so plainly: the app isn’t code-signed yet, and some parts need an internet connection on first use. Tell us what to improve and we’ll read it.
