Give post something it can actually solve.
A flat fill is only half the job. Glass Double bakes in the registration markers a matchmove needs — and lets you tune them to your lens.
Built-in tracking markers
Registration crosses, dots or a graph-paper grid, plus corner and edge marks — the fixed references a tracker needs to solve the screen's motion.
Green, blue, magenta or grey
Pick the chroma that won't spill on your subject — or a neutral grey plate for reflective, chrome or glass devices and luminance keys.
Adjustable marker density
Tune how many markers per axis, and toggle corners and edges, so the plate matches your lens and the size of the screen in frame.
Emissive glow control
Raise the fill's brightness so it throws realistic screen spill onto the actor, or keep it flat for a clean key.
Fills the real device
Render the fill full-screen on the actual phone on set, so the screen you replace in post is the exact one the camera saw.
Green-screen questions, answered
How do I track and replace a phone screen in post?
Put a Glass Double green-screen fill with registration markers on the phone in frame. The built-in corner, edge and interior markers give your tracker fixed references to solve the screen's corners, so VFX can corner-pin and replace the screen.
Green screen or grey screen for a phone?
Use green (or blue/magenta) as a chroma key on a matte device. Use the neutral grey plate for reflective, chrome or glass devices, for luminance keys, and for clean plates where chroma spill onto the subject would be a problem.
Can I control the marker pattern and density?
Yes — choose crosses, dots or a grid, set the density per axis, and toggle corner and edge registration marks so the plate suits your lens and screen size.
Does the fill spill light like a real screen?
An emissive control raises the fill's brightness and adds a soft glow, so it throws believable screen spill onto the actor — or you can keep it flat for a clean key.
