File Information
[b]Hilbert:[/b] Hey Rosy, I noticed your release includes subtitles. What’s the deal with them?  
[b]Rosy:[/b] Oh, good question! For this release, I’ve included two types of subtitles.  
[b]Hilbert:[/b] Two types? What’s the difference?  
[b]Rosy:[/b] Some of the subtitles are human-translated, mostly sourced from OpenSubtitles, so they’re usually very accurate.  
[b]Hilbert:[/b] And the others?  
[b]Rosy:[/b] The others are machine-translated using SubtitleCat. They’re great for less common languages, but they might not be perfect.  
[b]Hilbert:[/b] So, you combine them to cover more audiences?  
[b]Rosy:[/b] Exactly! It’s about giving everyone options, even if the machine-translated ones aren’t as polished as the human ones.  
[b]Hilbert:[/b] That’s smart. Thanks for explaining!

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"

    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
