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.
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.
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.
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.
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.
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.
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.
The camera turns as soon as the linked character moves. The field of view always stays correct.
Back-to-One spots crossing the line between two characters and warns you instantly – in red on the canvas.
Several cameras run at once as a setup, grouped by a shared color in the shot list
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.
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.
Move characters and cameras on a timeline and see the rhythm of the scene in real time.
From the real position of the sun to a dark set: Back-to-One thinks about the conditions you actually shoot in.
Back-to-One uses iCloud: your plan is always current on iPhone, iPad and Mac. No forced login, no third-party infrastructure.
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.





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.
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.
