M4VからWebMへの変換について
M4V is Apple's video format based on MPEG-4 with H.264 video and AAC audio, while WebM is Google's open, royalty-free video format using VP8 or VP9 video with Vorbis or Opus audio. WebM was specifically designed for HTML5 web video delivery. Converting M4V to WebM replaces Apple's proprietary-leaning codec stack with Google's open alternatives, producing files optimized for web embedding without patent licensing concerns.
M4VをWebMに変換する理由
WebM is the native video format for the web. All major browsers (Chrome, Firefox, Edge, Opera) support WebM natively in the <video> element without requiring any plugins or codecs. VP9 offers compression efficiency comparable to H.265/HEVC while remaining royalty-free. For web publishers who want to serve video without H.264 patent considerations, WebM is the standard choice.
