Resumen
MP4 es el estándar global para video, utilizado por todos los dispositivos, plataformas y aplicaciones. WebM es la alternativa de código abierto de Google para la transmisión web. MOV es el formato de Apple para edición profesional.
Elegir el formato correcto depende de tu caso de uso: compartir, transmisión web o edición profesional.

Three Containers, Shared Roots
All three are container formats. MP4 and MOV share a common lineage: the ISO Base Media File Format that underlies MP4 was derived from Apple's QuickTime (MOV) atom structure, so both organize media into nested atom/box elements.[1][5][6] WebM is a different lineage entirely, a restricted profile of the Matroska container designed by Google for the open web, holding VP8/VP9 or AV1 video and Vorbis or Opus audio.[3][4]
Codecs and Intended Use
MP4 typically carries H.264 or H.265 video and AAC audio, the combination with the widest hardware decoder support.[2] WebM deliberately restricts itself to royalty-free codecs, making it suited to open-standard streaming and HTML5 video.[4] MOV, retaining QuickTime's rich track model, is geared toward professional editing and can hold high-bitrate intermediate codecs, timecode, and multiple media tracks.[6]
Why MP4 and MOV Are So Similar
Because MP4 was standardized directly from the QuickTime format, the two are structurally close, and a file often carries the same H.264 and AAC streams in either container.[1][5] Converting between MP4 and MOV can therefore frequently be done by remuxing, rewrapping the streams without re-encoding. The practical difference is reach: MOV is native to the Apple ecosystem, while MP4 is the cross-platform default.
Royalty-Free by Design
WebM's defining characteristic is that it admits only royalty-free codecs, which is why it was created: to provide a web video format free of patent-licensing requirements for browser vendors and content providers.[3][4] MP4 and MOV commonly carry patented codecs such as H.264 and H.265, a difference that matters for open-web distribution but not for typical local playback.
Compatibility and Applications
MP4 is the universal interchange format, playing on virtually every device and platform.[1] WebM is used for open, royalty-free web streaming where modern browser support is present, often alongside an MP4 fallback.[3] MOV is used inside Apple-centric and professional editing workflows, though it is less portable across non-Apple consumer devices.[5]
