____________________________________________________________

2) Encoding by vmaf

Step 1 - Check VMAF with Ab-av1

1.1 AV1
Source resolution → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 98
1080p Downscale → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 96 --vfilter "scale=-1:1080"
720p Downscale → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 96 --vfilter "scale=-1:720"
Sample encode → sample-encode -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --crf 20

1.2 x265
Source resolution → crf-search -i "c:\file.mkv" --encoder libx265 --pix-format yuv420p10le --preset medium --min-samples 20 --enc x265-params=fastdecode=1 --min-vmaf 98
1080p Downscale → crf-search -i "c:\file.mkv" --encoder libx265 --pix-format yuv420p10le --preset medium --min-samples 20 --enc x265-params=fastdecode=1 --min-vmaf 96 --vfilter "scale=-1:1080"

Step 2 - HandBrake

Summary:
- Container: MKV

Dimensions:
- Cropping: None

Video:
- Encoder: AV1 (10-bit SVT)
- Framerate: Same as source
- Preset: 5
- Fast Decode: ✓
- Encoder Profile: Main

- Quality: CRF determined from "ab-av1"(1), or crf 15-20-25

Audio:
- DTS to Opus Conversion:
- DTS 7.1 → Opus @ 512 kbps

3) Encoding by vbr preset 5-7

Step 1 - recommended sizes:

400mb - av1 1080p 30min high quality
800mb - av1 1080p 60min high quality
1500mb - av1 1080p 120min+ high quality
4000mb - av1 1080p super high quality
4000mb - av1 2160p high quality
8000mb - av1 2160p 120min+ super high quality

Step 2 - recommended bitrate:

1000kbps - 1080p medium quality
1500kbps - 1080p high quality
2000kbps - 1080p high quality
4000kbps - 1080p super high quality
4000kbps - 2160p high quality
8000kbps - 2160p super high quality

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.
