Plots¶

Distortion and Consumption as a function of bitrate¶

Overall trend for all measures:

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

Result for a single video, including energy:

mendevi plot '<svtav1_vs_rav1e_vs_aom.db>' -x rate -x energy -y psnr -c encoder -m effort -wy profile -f "ref_stem=='park_joy'"

Link between distortion and energy for each encoder

Conclusion¶

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