M4V is a container video format that is exclusively for Apple products. It stores audiovisual and multimedia data into single file and uses a codec to compress file size. This results in a file that is easy to manage and store. While M4V files are very similar to MP4, they are designed for Apple products and Apple usually protects these files with FairPlay DRM.

 

How to open an M4V file?

M4V files open on Windows or Mac operating systems, in Apple iTunes for Windows and Apple iTunes for Mac, respectively. It is also possible to open M4V files in other media players, such as Adobe Premiere Pro, Media Player Classic, and several others.

 

Keep in mind that M4V is a container that holds various kinds of data, so if there is a problem opening the file, it usually means that data in the container (an audio or video codec) is not compatible with the device’s OS. To resolve this issue, try VLC media player.

WebM (WEBM) is a freely-licensed file container designed for the Web. Specifically, it was designed to be compatible with HTML5, originally. It supports chapters, captions, subtitles, metadata tags, streaming, attachments, 3D codecs, 3D containers, and hardware players. WEBM compresses video streams with VP8 or VP9 codecs, and audio with Vorbis or Opus codecs.

 

How to open a WEBM file?

VLC media player and MPlayer can open WEBM files on any operating system (OS). Other good choices for opening WEBM include Winamp for Microsoft Windows OS, and Elmedia for Mac OS X.

 

Microsoft browsers do not have built-in WebM codecs. Therefore, install the codecs separately. However, most browsers support WEBM files.
