Benji: Rosy, another "Mission Impossible" release? What’s going on? Is this a Proper?  
Rosy: Technically, it’s not a Proper in the strictest sense.  
Benji: Then what’s the difference? It feels like déjà vu.  
Rosy: The only difference is that I removed the AC3 and AAC audio tracks, leaving only the Opus track.  
Benji: Why go through the hassle for that?  
Rosy: Space-saving, Benji. It’s optimized for those who want to burn it onto a DVD9 for backup.  
Benji: DVD9 backups? People still do that?  
Rosy: You’d be surprised. Some like the security of physical storage without compromising quality.  
Benji: Hmm, I see your point. Still, doesn’t it limit options for playback?  
Rosy: Not really. Opus is well-supported these days, and this release is specifically aimed at backup enthusiasts.  
Benji: Fair enough. Just don’t tell Ethan. He’s already juggling enough missions.  
Rosy: Don’t worry, Benji. This one’s not self-destructing anytime soon.

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

   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
