av1 2160p 120min+ medium quality     - 4gb
av1 2160p 120min+ super high quality - 8gb-12gb

Step 2 - recommended bitrate:

1080p medium quality     - 1000kbps
1080p high quality       - 1500kbps
1080p high quality       - 2000kbps
1080p super high quality - 4000kbps

2160p high quality       - 4000kbps
2160p super high quality - 8000-12000 kbps
____________________________________________________________

3) Observations

AV1 presets have a significant impact on both bitrate and quality. For instance, moving from preset 5 to preset 2 can boost VMAF scores by 2-4 points. This behavior differs notably from x265, where higher-quality presets typically increase file size. In AV1, file size often remains unchanged or even decreases as quality improves with lower presets.

A good example is Netflix AV1 rips, which achieve decent quality at 1080p with astonishingly low bitrates of 500-700 kbps. This is likely due to the use of extremely low presets (2, 1, or 0), which require substantial computational power but yield remarkable results.

This demonstrates that bitrate alone is not a reliable indicator of quality. Similarly, relying solely on VMAF scores or subjective visual assessment can be misleading. A balanced approach that combines multiple evaluation methods is essential, particularly when faced with unusual cases, such as low VMAF scores despite high bitrates.
