MKV Files: Great for Pirates, Terrible for Normal People
MKV is like the Swiss Army knife of video formats — it can hold 10 audio tracks, 37 subtitle languages, and chapter markers. Cool if you're archiving the Lord of the Rings extended editions. Not cool when you just want to watch a movie on your TV.
This MKV to MP4 converter strips away the complexity and gives you a file that just works. Last week I converted a 40GB MKV with 7 audio tracks down to a 8GB MP4 with just the English audio. Same video quality, plays on my phone, uploads to Google Drive. Perfect.
