Previzion 0.3.1 is available →

Previsualize a scene from the script

Previzion turns a few lines into a storyboard, builds the 3D scene, moves the cameras and renders the sequence as an MP4. You direct, it does the setup.

Storyboard

From a script to storyboard cuts

Each cut comes with its framing, its camera move and a line of direction. Edit one, regenerate it, keep the versions you like.

  • Regenerate a single cut without touching the rest

Cameras

Direct the cameras, don't animate them

Pick one of eleven moves and what to film, and the camera moves on its own. It keeps up even with a speeding car. To fine-tune it, adjust it yourself on the Advanced tab.

  • Boom shots that rise like a crane, Rail shots that glide past on a track
  • Handheld, vehicle and impact shakes
  • Keyframes you can grab on the timeline

Make Scenes

The board becomes a 3D scene

One click on the storyboard page. The model reads the cuts, stands the city, the cars and the people, and lays a camera block per cut on the timeline. From there every block, key and object is yours to drag.

How it works

Four pages, in order

01

Script

A prompt, a few lines or a whole script. Pick the look and the length.

02

Storyboard

Cuts are drawn one by one. Ask for another take and the old one stays as a version. Spends Viz

03

Scene editor

Make Scenes builds the 3D scene. Every cut gets a camera block; drag any keyframe. Building spends Viz, editing does not

04

Preview & Export

Play the shot cameras, export an MP4 up to 4K, upload to the board.

FAQ

Questions people ask first

Is Previzion free?

Yes. The app is free; only AI generation spends Viz. The 100 Viz you get when you sign up make about three videos. Paid plans come later; see Pricing.

What spends Viz?

Generating a storyboard, regenerating a cut, making the scene from the board and asking the model to change it. Downloading, editing by hand, rendering on your machine and the board never do.

Does my Mac support Previzion?

Previzion supports Macs with Apple Silicon. Check Apple menu › About This Mac › Chip, then choose the Mac download. Intel Macs are not supported.

Do I need an account to download?

Yes. Sign in with Google, pick a nickname, and choose the Mac or Windows download. We use your verified Google account identifier and email.

Where do my projects live?

On your machine, as .pvz files. Uploading a movie to the board also sends the project file to the server. When you send feedback from the app, the open project file is attached unless you untick it.

Where is the user guide?

Under Help: installing, the four pages, the timeline, cameras, shortcuts and what to do when something goes wrong.

Does it run offline?

Editing, cameras and export run on your machine. Generating storyboards and scenes, asking the AI for changes and uploading to the board need a connection.
