Block the scene. Get the shot list.

Dario is a previz tool for filmmakers and content creators. Place your actors and cameras on a floor plan, plan the moves, and Dario draws the storyboards, builds the shot list and camera setups, and plays it all back as a 3D previz animatic.

How it works

One plan. Five stages.

You block the scene once, from overhead. Dario works out the rest from that real geometry, and the stage bar follows the order you work in. Press 1 to 5 to jump between stages.

  1. Shot Editor

    Draw the set, place actors, props and cameras, block the moves, and add a shot for each angle.

  2. Storyboards

    Every shot gets a frame drawn from your blocking in 3D, with move arrows. Nothing to sketch.

  3. Previs

    String scenes into a sequence and play it back as a 3D animatic, full-window in the Cinema viewer.

  4. Shot List

    Every shot in an editable table. Build camera setups and see the shooting order.

  5. Deliver

    Every export in one place: boards, shot lists, shot cards, setup lists and a video render.

Real previs and real boards

Nothing here was drawn by hand. Both come straight out of Dario from the blocking of our own film, FML: the animatic from the Previs stage, and the board page from Storyboards.

The shot list

Ready for the call sheet

Dario slates shots the way crews already do, as scene number plus shot letter, and gives each one a permanent Shot ID that is printed on boards, cards and the animatic. Lock a shot when it's final, then filter, sort and export the list as a PDF or CSV.

Features

Built for how a set actually runs

Blocking you can read

Actor moves are drawn like marks on the floor: a dotted path, an X where they start and a dot where they land. Each move shows its speed, so a sprint by accident stands out.

A live 3D camera

See what each camera sees as you place it. Real lenses from 12 to 200mm, true camera heights, tilt, dutch angles, and 16:9 through 2.39:1.

Eyelines and the 180° line

Turn on Annotate to see who looks at whom and where the line of action runs. A camera that crosses it gets a red ring.

Camera setups from real geometry

Build setups groups shots by camera position, lens and aim, then orders them for the day and flags every turnaround.

Storyboards drawn for you

Every shot gets a frame automatically, rendered from its camera at the start of the move, and it updates when the blocking changes. Capture your own moment from the timeline whenever you like.

Previs to your edit

Render the animatic as a PNG sequence with a shot marker list and import steps for DaVinci Resolve.

Paperwork for the whole crew

Shot lists and shot cards with storyboard frames, and setup lists for the AD. Export one scene, all scenes or a Previs sequence, at about 1 MB a scene.

Keys an editor knows

1 to 5 for stages, V, C and A for tools, and Space, J, K and L to play the animatic.

Your files, your work

A project is one file on your computer. Nothing is uploaded, there's no account, and everything works offline.

Offline on set

No signal at the location? Fine.

Dario installs from your browser like an app. Once installed, it opens and works without an internet connection.

  1. Chrome or Edge: File → About Dario → Install Dario.
  2. Safari on Mac: File → Add to Dock.
  3. Safari on iPad: Share → Add to Home Screen.
Who makes it

Made by a working filmmaker

Dario comes from SlicedCo, an independent production company. It started as the tool we wanted on our own shoots: something quicker than drawing overheads by hand, and simpler than production suites built for big studios.

We use it to plan our own films, and we'll keep shaping it around what directors, DPs and ADs tell us they need.

Public beta

Free while it's in beta

Every feature is open during the beta. Use it on a real project and tell us what works and what doesn't. Updates arrive on their own: when a new version is ready, Dario offers to reload.

Questions

FAQ

What does the beta cost?

Nothing. Dario is free during the beta. When the beta ends, Dario will move to a paid plan, and we'll tell beta users well ahead of time.

Where is my work saved?

On your computer. Saving downloads a project file you can keep, back up and send to your team. Dario also keeps an automatic copy in the browser to recover from a crash, but your project files are the real copy.

Do I need an account?

No. Open Dario and start blocking.

Which devices does it run on?

Chrome, Edge or Safari on a Mac or PC works best. Aiming cameras and rotating objects use right-click, so you'll want a mouse or trackpad. It opens on an iPad, but touch is awkward for now.

Can I use it without internet?

Yes, once you install it from the browser. See "Offline on set" above.

How do I report a bug or ask for a feature?

Get in touch through slicedco.com. We read everything during the beta.
