help NDI Tools (Virtual Input) FAQ
What is NDI Virtual Input used for?
NDI Virtual Input is a free driver that allows you to route an NDI video stream into applications that only support standard webcams, like OBS or Zoom. It effectively tricks your computer into seeing a remote network video source as a locally connected USB camera.
Who makes NDI Tools?
The NDI (Network Device Interface) protocol and accompanying software suite were originally developed by NewTek. NewTek was later acquired by Vizrt, who now oversees the distribution and development of the NDI Tools suite.
Is NDI Tools free to use for live streaming?
Yes, the NDI Tools suite is available as a completely free download for both Windows and macOS. Users can access high-quality, low-latency network video routing without paying any licensing fees.
Do I need a fast internet connection to use NDI Virtual Input?
NDI is designed primarily for use over a Local Area Network (LAN) rather than the public internet, so your local network bandwidth is what matters. A wired Gigabit Ethernet connection is highly recommended, as standard Wi-Fi often struggles to handle the heavy uncompressed video data.
