Recorded a 4GB Video Too Large to Send on Chat or Email? This 17k-Star Open-Source Tool Shrunk It to 180MB in 18 Seconds with Zero Visible Loss

【Video Compression Lab Benchmark】A 10-minute 4K video shot on a modern smartphone easily exceeds 4GB—triggering file-size rejections on messaging apps and email while commercial 'video compressor' apps demand $20 subscriptions and ruin quality. We benchmarked the 17,000-star free open-source transcoder HandBrake using GPU hardware acceleration (NVENC / Intel QSV / VideoToolbox) at Constant Quality RF 23: shrinking a 4.2GB 4K clip to 182MB in just 18 seconds with a 96.8 VMAF visual quality score.

We tested the 3MB MFT-direct scanner WizTree (scanning 580,000 files in 1.4 seconds vs. Windows Storage Sense's 195 seconds) to uncover the 4 hidden space hogs eating 112GB, and reclaimed it all in 5 minutes without reinstalling a single app.
