x264 vs. AV1 Real-Time Test Results

Video encoding requirements are diverse, so video engineers must maintain benchmarks on the state of all significant encoder implementations. Working with the largest streaming services and platforms, our team routinely collects performance data of open-source implementations compared to the Visionular Aurora family of encoders. In this study, we compared x264 to our Aurora1 AV1 encoder. Twenty 1080p videos representing various characteristics common to premium and UGC live streaming were selected. The encoders were operated on an AWS C5 AMD EPYC 7R32 instance (16 cores / 32 threads). We enabled 1, 2, 3, 4, 5, and 6 concurrent FFmpeg instances using the same...
