How do I convert MKV files to MP4 for free?
A problem people often face is converting videos from mkv to mp4 container/file formats for free and easily . It is actually effortless to convert mkv to mp4 using open-source software so that you don’t have to pay a dime!
Or in FFMPEG:
ffmpeg -i LostInTranslation.mkv -codec copy LostInTranslation.mp4

Hope that helps! `
