BirdDog recently published an article comparing the different versions of NDI, a game-changer in live video production. Since Full NDI debuted in 2015, new iterations like NDI|HX, HX2, and HX3 have emerged, offering improved efficiency and flexibility. Each version serves different production needs, balancing quality, latency, and bandwidth usage.
The Evolution of NDI and Video Technology
Just as video codecs evolved from MPEG-2 to H.265 for better efficiency, NDI technology has also advanced. Full NDI, based on MPEG-2, delivers top-tier quality with ultra-low latency but requires significant bandwidth. In contrast, newer versions like NDI|HX3 support H.264 and H.265, optimizing network performance without sacrificing quality.
NDI has revolutionized video production by enabling high-quality video transmission over standard IT networks, eliminating the need for expensive cabling. This has made professional-grade video accessible across industries, including broadcasting, corporate livestreams, sports, and education.
Full NDI vs. NDI|HX Versions
Full NDI remains the best option for studios needing the highest quality and lowest latency, but it demands more bandwidth. NDI|HX was introduced to provide a more network-friendly alternative using H.264 compression, making it ideal for setups with bandwidth constraints. NDI|HX2 further optimized network efficiency for remote video contributions, while NDI|HX3 enhances image quality, reduces latency, and ensures seamless device compatibility.
Choosing the Right NDI Format
Each NDI version caters to different workflow needs. Full NDI is ideal for high-end production, while NDI|HX, HX2, and HX3 offer more bandwidth-efficient options. With its balance of quality, efficiency, and interoperability, NDI|HX3 is quickly becoming the preferred choice for modern live video production. Understanding these differences helps content creators select the best solution for their setups, ensuring smooth, high-quality live streams.
