===================== AV1 guide v14 ========================

Step 1 - Check VMAF with Ab-av1

 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  

 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 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
- Subtitle Translator
- Whisper OpenAI
- Opensubtitles
- Subtitlecat
*If size is an issue don`t use pgs, prefer ass/srt.
____________________________________________________________

If encoding by vbr targeting size, recommended sizes are:
400,800,1500,4000,8000mb

Recommended bitrate are
1000,1500,2000 for 1080p
4000-8000 for 2160p

but check vmaf if possible.
