How we make
what you can't film.

This is how we work, one workflow at a time. Each method here has been tested on our own films and brought into productions alongside the crew, the edit and the people who sign it off.

changing channels.

Live broadcast, the living room, colour, the edit. Every few decades the way television is made changes, and the people who adopt it first shape what comes next. Scroll through ninety years of it, made as one continuous camera move.

Workflow 01 · Greybox to period world

Shoot it in a grey room,
finish it anywhere.

Period streets, lost buildings, places you'd never get a permit for.

The actor performs for real on a simple grey set. We build the finished world on the first frame, get it signed off as a still, then carry the whole take into that world with the performance and the camera move intact.

It suits period drama, historical reconstruction and any location that's gone, too costly or out of reach. The example here is The Watcher, a greybox test for a Victorian reconstruction.

Six steps, from the grey room to the edit

  1. 01

    Greybox

    The performance is filmed for real in a grey studio, with a few flats and some tape on the floor. It's lit roughly the way the finished scene will look.

    Frame one

    The first frame becomes the design stage. The world is built on that one still, from period reference, and signed off before anything moves.

    Transform

    The clip goes through the model and comes out in the new world, with the actor's timing and the camera move intact.

    Sign-off

    Every shot reaches the producer as a still first. Anything that doesn't work is redone before it's animated.

    Delivery

    Approved shots go straight into the edit with notes attached, ready to cut.

Sheets and approved keyframes

Characters and locations are drawn up as sheets before any shot is made, so every frame is built from the same references. The seven keyframes below were approved as stills before they were animated.

Workflow 02 · Lost places, rebuilt

Stand where it stood.
Watch it come back.

The Crystal Palace burned down in 1936. This teaser starts in the park at Sydenham today, rebuilds the glass palace as it was in 1899 from archive reference and fills it with visitors. Halfway through it stops to show how it was made, from the evidence to the true-scale model to the finished frame, then brings back the night it burned.

It shows how a history series can put a presenter in a place that no longer exists, and move between then and now in a single shot. The presenter here is an AI stand-in.

Built to scale before a frame is made

Nothing of the building survives to film, so the work starts with the record. The main dimensions come from period sources. The palace is then modelled at true scale in Blender, so every camera sees a building of the right size and shape.

Four cameras, from block model to finished frame

Each camera gives three guides: a block render, a depth map and a line drawing. The finished frame is made on top of them, so the architecture stays the same from shot to shot.

Five steps, from the record to the edit

  1. 01

    The evidence

    Plans, measurements and photographs of the building as it stood.

  2. 02

    Built to scale

    A plain 3D model at true scale, with cameras placed where a crew would stand.

  3. 03

    Checked

    The model is checked against period photographs. Where they disagree, the photograph wins.

  4. 04

    The finished frame

    Glass, ironwork, gardens and visitors in the dress of the time, signed off as a still.

  5. 05

    Then and now

    Approved frames are animated and cut against the park as it is today.

Workflow 03 · Characters and worlds that hold

TV is changing channels.
Everyone's coming along.

The old way and the new way, in one gondola. Two character sheets, one location and a fight that returns to its opening frame. It's a 28-second loop built through the same workflow we bring to a series, where every character has to look like themselves in every shot.

Workflow 04 · From the script to the sofa

From the script
to the sofa.

This is the production workflow behind the scroll film on our homepage. One script goes in at the top. What comes out is a cut, graded programme on a living room telly, with every shot traceable back to the page.

  1. 01

    The brief

    Every script is broken into shots, references and a continuity passport before anything is generated.

  2. 02

    The board

    Our platform tracks each frame from prompt to approval, so the edit always knows what it's cutting.

  3. 03

    The world holds

    Same rooms, same faces, same light, episode after episode.

  4. 04

    On air

    Cut, graded and on air.
