Jumbo frames are Ethernet frames with a payload larger than the standard 1500 bytes. Using them can improve network performance for high-bitrate streams like JPEG-XS by reducing packet header overhead. They are recommended for JPEG-XS services at bitrates of 300 Mbps and higher.
To use jumbo frames, you must configure them on your Beam device's network interfaces and in the Live Encoder service.
Configure Jumbo Frames on Network Interfaces
To use jumbo frames for a JPEG-XS stream, you must first enable them on the network interfaces of your Beam device by setting a higher Maximum Transmission Unit (MTU).
See Configure Jumbo Frames for instructions.
Enable Jumbo Frames in the Live Encoder Service
After configuring the network interfaces, enable jumbo frames for the specific Live Encoder service.
- In the Live Encoder service configuration, go to the Input tab and ensure the Contribution encoding service checkbox is checked.
- Under the Encoding tab, ensure the codec is set to JPEG XS 4:2:2 or JPEG XS 4:2:2 10 bits.
- In the output properties under the Output tab, check the Ensure Large Frames checkbox.
