Plots

Distortion as a function of bitrate

mendevi plot '<svtav1_vs_rav1e_vs_aom.db>' -x rate -y psnr -y vmaf -wx category -c '(encoder, profile)' -m effort

Conclusion

1. libvstav1 is significantly faster than librav1e! This difference is even more pronounced at higher throughput rates.

2. librav1e allows for lower bitrate (in constant quality mode).

3. Although librav1e shows better distortion at high bitrates, libsvtav1 is better at equal encoding duration.
