A graph depicting AV1 coding efficiency, based on the 1080p park_joy clip from Derf's Test Media. aom-av1-lavish (based on aomenc) takes the lead here, while Aviator's SVT-AV1 tune (tune 2) comes in second. Tune 1 is a close third, while Tune 0 & rav1e come in a close third & a more distant fourth. While rav1e & the two stock SVT-AV1 tunes are nearly identical near the higher end of the quality range, tune 2 & lavish clearly pull ahead. Seeing SVT-AV1 come closer to lavish is very impressive considering the different design goals of the two encoders, with SVT-AV1 being primarily focused on speed & parallelization.

Today I released Aviator 0.4.0 for #linux. Besides the audio filters, this is a special release because the version of SVT-AV1 I'm shipping features custom psychovisual optimizations & a new tune that seems to prove itself in real-world testing. My eyes agree with the metrics here, and this was only possible with #Flatpak, which lets me ship my own version of SVT-AV1 that is different from the system's. Look at that, a GUI outperforming most CLI implementations by default! #av1
