Back-to-One

Script · Blocking · Ready.

Back-to-One reads your screenplay and creates every scene and character automatically. Then you block characters, cameras and light on the top-down canvas, instead of starting from scratch.

Back-to-One: blocking canvas with the prop library open, multiple camera setups and an automatic shot list
Easy start

Script in.
Project ready.

Import your screenplay as FDX or PDF and Back-to-One builds a project with every scene (including its slugline) and every character, optionally placed on the canvas right away.

Instead of creating every scene and character by hand, you start at the blocking.

  • Scenes and characters created automatically from FDX or PDF
  • PDF scripts are read even without Final Draft structure
  • Clean up the cast before importing, merge or delete roles
  • Characters optionally placed per scene
  • Each scene's text shown in proper screenplay format
27  INT. APARTMENT – KITCHEN – NIGHT
Tom stands at the window, lost in thought. Hanna comes in.
HANNA
I was waiting for you.
TOM
I know.
Hanna puts the key on the table.
HANNA
You were there again.
TOM
Only briefly. It's not what you think.
She looks at him and waits.
HANNA
Then explain it to me.
Tom turns away. He is crying.

Scene 27 · INT · Kitchen · NightHANNATOM

The room comes out of your pocket.

The screenplay builds your scenes. Now the iPhone builds your room. Walk through the location once and the floor plan is there, with real measurements.

  • Not a raw scan, a floor plan. Straightened, snapped to right angles, corners closed.
  • Doors and windows are detected too. They attach to the walls, placed by measured width, with a real opening cut into the wall.
  • Walls or background image, your call. The app asks after the scan instead of taking it off your hands.

The room scan needs LiDAR, so an iPhone Pro or an iPad Pro.

Recorded in the app. The top line shows sensor, aspect ratio and the angle of view, which changes with the focal length.

Viewfinder

See the frame
before the camera arrives.

Hold the device in landscape and see the location at the focal length you will shoot. Take the frame and it lands on the shot as a storyboard image, in the aspect ratio of the production.

  • Focal lengths from the project lens set
  • Sensor-accurate across six formats, anamorphic included
  • The frame lands on the shot, no detour through Photos
  • On iPhone and iPad
Integrated script panel: screenplay text next to the canvas, lines assigned to cameras, colored revisions
Script

The screenplay stays in view.

The scene sits as a screenplay right next to the canvas. Pick a camera and assign the lines it covers. You see at a glance which shot carries which text.

  • Screenplay text right next to the canvas
  • Assign lines to individual cameras
  • Colored revisions for draft versions
  • Import a script or revised pages
The Core

Staging that thinks with you.

Place characters, cameras and light. The camera aims itself, multiple setups run in parallel, and crossing the line shows up while you plan – not in the edit.

Automatic camera aim

The camera turns as soon as the linked character moves. The field of view always stays correct.

180° line checker

Back-to-One spots crossing the line between two characters and warns you instantly – in red on the canvas.

Multi-cam setups

Several cameras run at once as a setup, grouped by a shared color in the shot list

Everything at a glance

Canvas, shot list and tools – one workspace.

Scale & measuring

The plan holds up. On paper too.

You set what one grid square means. From then on everything follows: the scale bar on the canvas, the ruler, and every print-out the crew is holding.

Grid scaleSet once what a square stands for
Scale barAligned to the grid, correct at every zoom level
Metres or feet and inchesSet per project, identical on every device and every print
RulerTap two points, read the distance. Snaps to object centres and wall corners
Shot List & Planning

The shot list writes itself.

Every camera creates a shot, linked both ways with the canvas. But it never stays a flat list. It thinks like a shooting plan and comes with you to set.

  • Grouped by camera setup (1A/1B), shot in one go
  • Shooting time belongs to the setup, not the single camera: three cameras at ten minutes each cost ten, not thirty
  • Shot sizes in the language you work in: Extreme Wide · Wide Shot · Full Shot · American Shot · Medium Shot · Medium Close-Up · Close-Up · Extreme Close-Up
  • Check off live on set: open / shot / cut
  • A storyboard image per shot, shown in the aspect ratio you actually shoot
  • Shoot day per scene and shoot-day filter
  • Switch quickly between the scenes
Animation

Play the scene before you shoot it.

Move characters and cameras on a timeline and see the rhythm of the scene in real time.

  • Timeline with keyframes, play, loop, speed
  • Camera moves and orbits on clean Bézier curves
  • “Follow”: the camera tracks a character automatically
  • Props and lights animate too, not just characters and cameras
  • “Move from”: entrances as a ghost with a footprint trail
Interior & Exterior

Ready for the shoot day.

From the real position of the sun to a dark set: Back-to-One thinks about the conditions you actually shoot in.

  • Scenes can be linked to shoot days
iPhone, iPad and Mac

One plan, every device.

The Mac at the desk, the iPad on set, the iPhone in your pocket. The same project through iCloud, no export and no detour. Light stage for working, dark for a blacked-out stage.

Deliverables

It ends with a finished hand-out.

What the crew needs goes out as a PDF: the plan, the shot list and the storyboards. No rebuilding in other tools, no app required on their end. Exports always render on a light stage, the scale bar is included even when it is hidden on screen, and the files stay small enough to email.

Collaboration

The team looks on. No subscription.

Anyone invited into a project, the production designer, the gaffer, the first AD, needs no subscription of their own to open it. The plan sits on their own iPhone, iPad or Mac, and changes arrive by themselves. The person who builds the plan pays. The whole team gets to read it.

See the progressOpen, shot, dropped, with a counter
Measure for yourselfThe ruler works without Pro, measuring changes nothing
PermanentlyNot just during the free week. An invitation does not turn a viewer into a customer on a clock
What is missingEditing and export. A quiet line at the top says why, instead of buttons doing nothing
