NDI Test Patterns
NDI Test Patterns is a macOS video calibration tool that sends test patterns and audio tones over an NDI network for setup, checking, and troubleshooting.
What is NDI Test Patterns?
NDI Test Patterns is a macOS utility for generating video test patterns and audio tones across an NDI network. It helps video professionals, streamers, and production teams check signal quality, confirm color and level consistency, and troubleshoot feeds before or during live workflows. The app can broadcast standard calibration patterns such as color bars and IRE fields so other NDI-enabled devices and monitors on the network can receive them. It also supports adding custom images, including images with embedded alpha, for overlay and source testing. On Mac, it is commonly used as part of the broader NDI Tools package in studios, streaming setups, and other IP video environments. NewTek originally developed NDI, and current NDI downloads and documentation are provided through the NDI website.
Key features
- Generate standard video test patterns for NDI receivers on the local network
- Send audio test tones to check levels and signal paths
- Use color bars, solid colors, and IRE fields for calibration work
- Load custom images for source and overlay testing
- Share a live NDI test signal immediately after launch
- Help troubleshoot networked video quality before live production

Safety overview
Status: Safe
This is a legitimate media-production utility used to send diagnostic video and audio signals over an NDI network. Network access is normal for its purpose, and users may see it appear as an available NDI source on the same network. It is generally safe to keep if you use NDI workflows. If you do not use NDI video tools, removing it should only affect your ability to generate test patterns from this Mac.
Recommendation: Keep NDI Test Patterns if you use NDI for streaming, studio production, or AV setup work. If you do not use NDI tools on this Mac, you can remove it without affecting unrelated apps, though NDI-based testing and calibration tasks will no longer be available.
