We’ll explore the key benefits of 4K, tackle common challenges, and help you decide if it’s the perfect upgrade for your event production. Don’t miss this opportunity to take your live streams to the next level!
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.
- 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
- NDI HX3 Efficiency: Improved efficiency for high-quality, low-latency video transmission over standard Ethernet networks.
- HDR Support: Native HDR support for more life-like video with higher contrast and expanded brightness headroom1.
- 10-bit Color Depth: Native 10+ bit color depth support for smoother gradients, richer textures, and pixel-perfect precision
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
