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.
MP3 Audio Format MP3 Converter
MP3 is the most common format for storing and playing digital music. It’s short for ‘MPEG-1 Audio Layer 3’, and it was developed in the early 1990s as a way of compressing audio to create smaller files that could be easily shared and stored without losing too much sound quality.
MP3 is a universal format maintained by the International Office for Standardization (ISO). MP3 tracks will play on almost any device and with most media players, including Windows Media Player and Apple Music. Digital music took off in the 1990s and 2000s, and many users used media players to ‘rip’ CDs, or download tracks from sites like Napster, turning MP3 into the most common audio format. Because MP3 uses ‘lossy’ compression that can’t be reversed, some music listeners prefer to use other formats such as FLAC, even if the file sizes are bigger.
