Overview
Most people have never seen what a shot looks like before it works. This one puts both halves in the same frame.
A vertical piece built for a feed, where attention lasts about a second and a half. The reveal is the hook: flat green wall, then the world that replaced it.
It is a small file with a specific purpose — to make the invisible part of the job visible without turning it into a lecture.
The film
Thirty-nine seconds, both sides of the seam.
The challenge
A clean key is only half the work.
Pulling the green is the easy part. Making the subject belong in the new environment — edge detail, spill, contact shadow, matching contrast — is where the hours go.
In a before-and-after the standard is higher than usual, because the viewer is looking directly at the join.
Creative direction
Vertical first, reveal early.
- Cut for sound off — it has to read silent
- Reveal placed inside the first two seconds
- Edge treatment kept honest, not over-softened
- Grade matched across both halves so the switch is the only change
My role
Keyed it, composited it, cut it.
Post only — the value here is entirely in the compositing and the timing of the reveal.

Reflection
Why show the mechanism.
Explaining the trick does not reduce it. If anything, people trust the finished frame more once they have seen what it was built from.
Showing the wires is not a weakness. It's the only honest way to prove the shot.
