Corridor Key Download & Install Guide: How to Get Started (2026)

How to Download and Install Corridor Key

Looking to download Corridor Key for green screen removal? There are two ways to use it: the local open-source version (requires technical setup and a powerful GPU) or CorridorKey cloud (no download needed — works in your browser).

Option 1: CorridorKey Cloud (No Download Required)

The fastest way to start using Corridor Key. No installation, no GPU required.

How to get started:

1. Go to corridorkey.app
2. Click "Get Started" to create a free account
3. Upload your green screen footage
4. Get a free single-frame preview
5. Process your full video ($0.10/GPU min)
6. Download your results (composite + alpha matte)

Why choose cloud:

• Zero installation — works in any web browser
• No GPU required — processes on L40S cloud GPUs
• Always the latest AI model
• Free preview before paying
• Works on Mac, Windows, Linux, even tablets

Option 2: Local Installation (Advanced Users)

The open-source Corridor Key can be installed locally if you have the right hardware. This requires technical knowledge and a compatible NVIDIA GPU.

System Requirements:

• GPU: NVIDIA GPU with 8GB+ VRAM (RTX 3070 or better recommended)
• RAM: 16GB minimum, 32GB recommended
• Storage: 10GB+ free space for models
• OS: Windows 10/11 or Linux (Ubuntu 20.04+)
• Software: Python 3.10+, CUDA toolkit, Git

Installation Steps:

1. Install prerequisites

• Install Python 3.10 or newer
• Install NVIDIA CUDA toolkit (version 11.8 or 12.x)
• Install Git

1. Clone the repository

• Download from the official GitHub source
• Extract or clone to your preferred directory

1. Run the installer

• Windows: Double-click the install script
• Linux/Mac: Run the shell install script
• This downloads AI model weights (~4GB) and installs dependencies

1. Start the application

• Windows: Run the start script
• Linux/Mac: Run the shell start script

1. Process your footage

• Drag and drop video files onto the application
• Wait for processing (speed depends on your GPU)
• Find results in the output folder

Common installation issues:

• CUDA errors: Make sure your NVIDIA drivers are up to date
• Out of memory: Your GPU needs at least 8GB VRAM
• Slow processing: 4K footage requires 12GB+ VRAM for reasonable speed
• Python errors: Make sure you're using Python 3.10+, not an older version

Cloud vs Local: Which Should You Choose?

The Verdict

Choose CorridorKey Cloud if:

• You don't want to deal with installation
• You don't have a powerful NVIDIA GPU
• You want the fastest, highest-quality results
• You process videos occasionally (pay-as-you-go is more economical)

Choose Local Install if:

• You have a powerful NVIDIA GPU (RTX 4080+)
• You process a very high volume of footage regularly
• You need to work offline
• You're comfortable with command-line tools

Most People Should Use the Cloud Version

Unless you're a technical user with a high-end GPU, CorridorKey cloud is the better choice. No installation headaches, no CUDA compatibility issues, no model downloads — just upload and get professional results.
