What is a M4V file?

M4V is Apple’s take on the MP4 video container, used by iTunes for films and TV shows. It is almost identical to MP4, but store-bought M4V files can carry DRM copy protection; renaming to .mp4 often works, otherwise a real conversion is needed.

How to open a M4V file

M4V plays in QuickTime, iTunes/Apple TV and VLC; for wider support convert it to MP4.

What is a WebM file?

WebM is an open, royalty-free video format built for the web. It streams efficiently at small file sizes and is supported natively by modern browsers, which makes it ideal for online video and HTML5 players.

WebM plays in all current browsers (Chrome, Firefox, Edge) and VLC; older devices or editing software may need it converted to MP4.
