Conclusion¶

libvstav1 is significantly faster than librav1e! This difference is even more pronounced at higher throughput rates. speed(librav1e) > speed(libsvtav1).
librav1e allows for lower bitrate (in constant quality mode).
Although librav1e shows better distortion at high bitrates, libsvtav1 is better at equal encoding duration.
