What is 4K?

  • 4K is 3840 x 2160 pixels, which is four times the detail of 1080p (1920 x 1080 pixels).​
  • Increased pixel count results in much sharper and more detailed images, making every frame look crisp and clear.​
  • 4K resolution enhances color depth and vibrancy, providing a more lifelike and immersive viewing experience.​
  • Perfect for sports events, concerts, and high-end corporate presentations.​

4K PTZ Cameras

  • Capture in Higher Quality​
  • Record in 4K even if you are producing HD​
  • Leaves room to make edits and keep quality or use a digital zoom when needed​
  • Available from most of our manufacturers:​ BirdDog, Canon, JVC, Marshall, Panasonic, PTZOptics, Vizrt​

​Software & Hardware with 4K Integration​

Software​

Hardware:​

​NDI Technology & 4K​

  • NDI HX 3 High-Quality Video Transmission​: Low-latency video over IP networks​
  • Ideal for 4K Streaming/transmitting video on a local network​: Send your video anywhere on the open web, or a closed network​
  • Integration with Existing Workflows​: Seamlessly integrate more equipment into current production combing legacy cameras and NDI compatible cameras​

​NDI 6 Expands 4K NDI Capabilities​

Best Practices for using 4K

  • Network Requirements​
  • Advantages of using a 4K workflow​
  • Future proofing content​

Network Requirements​

  • Ensure you have a high-speed internet connection capable of handling the increased data rate of 4K streaming. A minimum of 25 Mbps per stream is recommended​
  • While wireless networks are convenient, wired connections (Ethernet) are more reliable for 4K streaming due to their stability and higher bandwidth capabilities​
  • Ensure your network is free from congestion by limiting the number of devices connected simultaneously. Use network management tools to monitor and optimize traffic​
