VOB, standing for Video Object, is a video container format for DVD-Video media which can contain a stream with digital video, audio, subtitles, navigation content and DVD menus mixed. Generally speaking, DVD/VOB supports default DVD Player application or Windows Media Player on Mac and Windows operating systems, bur not supported by most portable devices. Usually, you will find VOB videos in the .vob file name extension stored in the VIDEO_TS folder,
WMV, short for the Windows Media Video, has become the main video format in Windows platform. A WMV file (.wmv) is generally ASF file with Windows Media Video codec and usually some version of Windows Media Audio codec. Actually, for Windows users, WMV won’t cause many format compatible problems, while for those Mac users; WMV is an unfriendly video format. This is a common problem, but users can solve it through video conversion.
MKV, also known as MatrosKa Video, is the open standard Matroska Multimedia video container format. MKV is one of the most popular video formats, partially because of its compatibility with almost any video codec in the world. And many videos shared on popular video share sites have the file extension name MKV.
M4V is a video format developed by Apple and thus widely used on Mac platform. Apple’s movies, TV episodes, and music videos in the iTunes Store are usually encoded in M4V format. Generally to say, M4V is a video format similar to MP4, so we can call it “MP4 Video Variant”, while the main difference between the two is that unlike MP4, M4V encodes AC3 (Dolby Digital) audio in a special way, which results in the failure to play M4V on some devices or edit M4V with some video editing software.
3GP is a multimedia file format used on 3G mobile phones. However, it’s also playable on 2G and 4G mobile phones. 3GP is similar to 3G2 and MP4, which are all based on the MPEG-4 Part 12 standard. To play on mobile phones, 3GP is created with the demands of limited storage and bandwidth use. As iMovie and Final Cut pro doesn’t support 3GP, users can’t play 3GP on iPhone, iPod, iPad, etc.
