Because they are so good at storing audio, MP3 files have become the de facto standard for music software, digital audio players, and music streaming sites. No matter which operating system or device you own, you can be confident MP3s will work right out of the box without a hitch. It's why MP3 players might still be worth buying.
The main reason they're so popular is the way the file type works. MP3s use lossy compression, which vastly reduces the size of an audio file while barely affecting its quality. The process works by stripping out all the data that's beyond the hearing range of the average person, then compressing the rest as efficiently as possible.
MP4 files are "containers" -- instead of storing the code for the file, they store the data. As such, MP4 files do not have a native way of handling the coding of the file. To determine how the coding and compression will be handled, they rely on specific codecs.
There are hundreds of codecs out there today, but not many will work with mainstream MP4 players. In order for a player to be able to read and play an MP4 file, it must have the same codec itself. The most widely-supported codecs are:. These codecs give MP4s a lot more flexibility than MP3.
The choice on quality resides with the user. Either way the file will appear as an MP4 file, but the data within the file will differ vastly. Besides audio, MP4 files can also contain video, images, and text. You'll often see various file extensions that give an indication of the type of data within the container. Here are some of the most common:. Because MP4 is a standardized file format for video, almost all video players support MP4. Windows and macOS users can play MP4 files without having to install any third-party software.
If, however, you prefer a different video player than either of those, changing the association of a file is a simple process on either Windows or macOS. When you install a new video playback app, the chances are high that the new app will claim the association with MP4 files during installation, unless specified otherwise. It got its name from the Russian word for Nesting Dolls, matryoshka.
The Matroska project was developed as an open standards project, which means that it is open source and completely free for anyone who wants it for personal use. The company also has a lot of resources on their website, including a list of playback options.
As time went on, the format was improved and in , it became the basis for the WebM multimedia format. MKV files are not an audio or video compression format. MKV files are actually multimedia container formats. An MKV container can incorporate audio, video, and subtitles into a single file—even if those elements use different types of encoding. For example, you could have a MKV file that contains H.
You have two main options for playing MKV files: using an MKV compatible media player or downloading the appropriate codecs for the media player you prefer. WebM is an open, royalty-free, media file format designed for the web.
WebM defines the file container structure, video and audio formats. WebM files consist of video streams compressed with the VP8 or VP9 video codecs and audio streams compressed with the Vorbis or Opus audio codecs. Openness and innovation.
