MKV Video Format

MKV Converter

MKV is an audio-visual file format, and the name MKV stands for Matroska Video File. Matryoshkas are Russian dolls, and, like several other video formats, MKVs are container files that can have audio, video, subtitles and metadata ‘nesting’ within them. While it’s not necessarily an industry standard like MP4, MKV is an open-source format that doesn’t belong to one single tech company.

MKV files are not compressed, so they can be much larger files than some other video formats like MP4, although the quality can be higher. Users can also ‘mix and match’ the audio and video elements in the file, or have multiple audio tracks (e.g. for different languages). These features make MKV popular with some filmmakers and editors. Not all media players support MKV. However, MKV videos will usually play on Windows 10, and with VLC and MPlayer, and you can install MKV codecs for other players.

VTT Document Format

VTT files are text files which contain extra information about web videos, such as subtitles, captions, descriptions, chapters, and metadata. The standard for Web VTT was developed by the World Wide Web Consortium (W3C) in 2010 in response to a perceived need for greater flexibility when displaying video online. Each VTT file contains timed text tracks on single line or multiple lines, with data about subtitles to display. Files are similar to another popular subtitle format, the SRT file, but VTT is more extensible - it allows for customisation of font-sizes and colours and the ability to store metadata about the video, such as the title and the author. Popular video sharing sites such as Youtube and Vimeo support VTT files, and they can also be used on social media platforms such as Facebook, Twitter and LinkedIn.
