Understanding 4K Encoding Requirements
4K video requires significant bandwidth and processing power. Before configuring your PVI encoder, ensure your network infrastructure can support the high data rates associated with 4K streams. This includes sufficient upload speed and a robust network backbone.
Configuring Resolution and Bitrate
Access your PVI encoder's web interface. Navigate to the video settings. Select the appropriate resolution, typically 3840x2160 or 4096x2160. For bitrate, start with a range of 15-25 Mbps for H.265 (HEVC) or 25-50 Mbps for H.264, adjusting based on content complexity and network capacity. Higher bitrates generally mean better quality but require more bandwidth.
Optimizing Codec and Profile
For 4K, H.265 (HEVC) is highly recommended due to its superior compression efficiency compared to H.264. Select the Main 10 profile if available for better color depth. Ensure your PVI encoder supports HEVC for efficient 4K encoding. Verify that your playback devices and network are also compatible with HEVC.

Frequently Asked Questions
What is the recommended codec for 4K on PVI encoders?
H.265 (HEVC) is highly recommended for 4K streaming due to its efficiency. H.264 can also be used but requires significantly more bandwidth.
How much bandwidth do I need for 4K streaming?
For 4K HEVC, aim for at least 15-25 Mbps. For H.264, you'll need 25-50 Mbps or more, depending on content.
Can my PVI encoder handle 4K if it's an older model?
Check your PVI encoder's specifications. Newer models are more likely to support 4K and HEVC encoding effectively.
What resolution options are available for 4K?
Common 4K resolutions include 3840x2160 (UHD) and 4096x2160 (DCI).
