What is chromakey?
Chromakey (or chroma key) is a visual effects technique used in film, television and video production to replace a specific colour in an image with another background. Green and blue are used most commonly because they contrast well with human skin tones and are easily isolated in post-production.
What is chromakey used for?
Chromakey is used to:
Replace backgrounds in film and TV
Create virtual sets
Add CGI environments
Composite actors into digital scenes
Support motion capture and virtual production
It is widely used in film, broadcast, commercials, VFX, gaming and XR production.
Why are green and blue the most common chromakey colours?
Green and blue are used because:
They are less common in skin tones
Cameras capture them cleanly
They provide strong contrast
They key efficiently in post-production software
Green is typically preferred due to higher sensor sensitivity, while blue is often used when subjects contain green elements.
What is digifoam chromakey fabric?
Digifoam chromakey fabric is a foam-backed chroma key material designed for professional production use. It combines a colour-accurate chromakey surface with a foam backing to improve performance, durability and ease of installation.
What are the benefits of foam-backed chromakey fabric?
Foam-backed digifoam fabric offers several advantages over traditional flat fabrics:
Improved light absorption
Reduced reflections and hotspots
More even colour across the surface
Better spill control
Crease resistance
Cleaner keying results in post-production
These benefits help reduce lighting issues and post-production clean-up.
How does foam backing improve chroma key results?
The foam backing:
Absorbs excess light rather than reflecting it
Helps maintain even colour under varied lighting
Reduces shadows and inconsistencies
Minimises ripples and surface imperfections
This results in cleaner edges and more reliable keys.
Is digifoam better than traditional green screen fabric?
For professional environments, yes. Foam-backed digifoam is generally superior because it offers:
- Greater consistency
- Better durability
- Improved visual performance on camera
- Reduced post-production time
Traditional fabrics may be suitable for basic use, but digifoam is preferred for film, broadcast and VFX workflows.
How is chromakey digifoam fabric installed?
Digifoam chromakey fabric can be installed in several ways, including:
Wall-mounted systems
Ceiling-hung installations
Tensioned frames
Freestanding or temporary rigs
The method depends on whether the installation is permanent or temporary.
Can chromakey fabric be installed permanently in a studio?
Yes. Digifoam chromakey fabric is ideal for permanent studio installations, including:
Film and TV studios
Sound stages
Broadcast studios
Virtual production environments
Permanent installations provide maximum consistency and long-term reliability.
Can the fabric be used for temporary or location shoots?
Yes. Digifoam fabric is also suitable for:
Temporary studio setups
Location shoots
Commercials and music videos
Rented production spaces
Its durability and crease resistance make it practical for short-term use.
Does chromakey fabric need to be stretched or tensioned?
For best results, yes. Proper tensioning:
Prevents ripples and shadows
Maintains an even surface
Improves lighting consistency
Produces cleaner keys
Our installation services ensure correct tensioning.
Does chromakey fabric affect lighting requirements?
Yes. High-quality digifoam fabric:
Requires less corrective lighting
Produces fewer hotspots
Allows more even illumination
Reduces light spill onto subjects
This can simplify lighting setups and reduce shoot time.
Can chromakey fabric be used with LED lighting?
Yes. Our chromakey fabrics are suitable for use with modern LED lighting systems, including high-output studio and virtual production lighting.
Does foam-backed fabric reduce colour spill?
Yes. Foam-backed digifoam fabric helps:
Absorb excess light
Reduce colour bounce
Minimise green or blue spill on subjects
This improves edge detail in post-production.
Is your chromakey fabric compatible with all keying software?
Yes. Our fabrics work with all major keying tools, including:
Adobe After Effects
DaVinci Resolve
Nuke
Final Cut Pro
Unreal Engine pipelines
Will better chromakey fabric reduce post-production time?
Yes. High-quality chromakey fabric can significantly:
Reduce keying artefacts
Minimise roto work
Improve edge quality
Speed up compositing
This saves time and cost in post-production.
Do you offer custom sizes?
Yes. We provide cut-to-order chromakey fabric in custom sizes to suit:
Studio walls and floors
Large sound stages
Non-standard configurations
Can I order samples before buying?
Yes. We offer chromakey fabric samples and swatches so you can test colour performance with your cameras and lighting before committing to a full order.
Do you supply fire-retardant chromakey fabric?
Yes. Fire-retardant options are available for:
Professional studios
