===================== AV1 guide v20 ========================


1) TLDR ez recipe


Handbrake

svt-av1 10 bit

Preset 5-7

crf 25

fast-decode

____________________________________________________________


2) Encoding by crf


stv-av1 10 bit crf 25 - high quality

stv-av1 10 bit crf 20 - very high quality

stv-av1 10 bit crf 15 - super high quality

stv-av1 10 bit crf 10 - max quality (usually from here file gets bigger than original)

____________________________________________________________


3) Encoding by crf + 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"

720p 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=-1:720"


Step 2 - HandBrake


Summary:

- Container: MKV


Dimensions:

- Cropping: None

- Anamorphic: None

- Borders: None


Video:

- Encoder: AV1 (10-bit SVT)

- Framerate: Same as source

- Preset: 5

- Fast Decode: ✓

- Encoder Profile: Main

- Encoder Level: Auto

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


Audio:

- DTS to Opus Conversion:

- DTS 7.1 → Opus @ 512 kbps

- DTS 5.1 → Opus @ 384 kbps

- DTS 2.0 → Opus @ 128 kbps

*When passtrough? lossy codec(opus,aac, ac3, eac3,wma) 768-128 kbps


Step 3 - Subtitles


- Original → passtrough

- Whisper OpenAI

- Opensubtitles

- Subtitlecat

*If size is an issue don`t use pgs, prefer ass/srt.

____________________________________________________________


4) Encoding by vbr preset 5-7


Step 1 - recommended sizes:


av1 1080p 30min high quality - 400mb

av1 1080p 60min high quality - 800mb

av1 1080p 120min+ high quality - 1600mb

av1 1080p super high quality - 4000mb - 4600mb


av1 2160p 120min+ medium quality - 4000mb - 4600mb

av1 2160p 120min+ high quality - 6000 - 8400mb

av1 2160p 120min+ super high quality - 12000 - 16000mb


Step 2 - recommended bitrate:


1080p medium quality - 1000 kbps

1080p high quality - 1500 kbps

1080p very high quality - 2000 kbps

1080p super high quality - 4000 kbps


2160p medium quality - 3000 - 4500 kbps

2160p high quality - 4500 - 6000 kbps

2160p super high quality - 12000 - 16000 kbps

____________________________________________________________


5) 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.
