The results show that the JPEG XS codec is fast enough for real-time processing for resolutions up to UHD 10bit. The overall frame rate is 170+ fps for 8bit and 145+ for 10bit video on a server machine. For 8K formats, we expect more optimization for multi-core processors to perform decoding and encoding faster in the future version of the codec. Also, due to a high video bitrate, it is recommended to use a really fast SSD for encoding - on a server machine the recording speed was the bottleneck for encoding tests and not the CPU load.
