The first thing to understand is that the file extension itself is not just a “format”, but a container for the video itself and the codec to decrypt the files. This means that very different codec file formats can really understand them, so two AVI files, for example, can use completely different codecs, but the file is still in AVI format.

What is Codec?
The codecs themselves are another source of confusion, a codec is simply the algorithm used to compress the video file, and some focus on quality, but it does not reduce the size as much as others, some create much smaller files, but with a greater loss of quality. The choice of codecs is somewhat dictated by the file format, but as we said, size can and does have the ability to use multiple codecs.

MP4
The first format we are looking at is MP4, which is actually a multimedia format because it can be used not only for video, but also for audio-only media. A platform format, they refer to the QuickTime MP4 file format and are in fact almost identical to the format. MP4 is an open source format, so it is available for anyone to use, with no license fees, one of the reasons it has gained popularity with encryption software manufacturers.
MP4 tends to produce smaller files than other similar formats, while maintaining a comparable quality level for production, and is excellent for capturing high-speed action without introducing motion blur, which can be a compressed scene feature of this. nature.
Part of the conditionality format that really impresses is that ten files remain the same regardless of the player or their platform, this reliability means that by using this format you can be sure of the results, no matter which device is finally viewed.
AVI
AVI stands for Audio Video Interleave and is one of the most popular video formats created by Microsoft and has been the primary video format for its included video player in Windows since 1992. As such, it has become familiar to a large user base. and then as a result, it has been adopted in a wide range of devices, although the way the size of the operation does not automatically set the aspect ratio of information and AVI files as they are seen on different players, let alone on different platforms, they may appear in different mode.
This inconsistency is in stark contrast to MP4, AVI, although it is not marked as compatible with a wide range of codecs, as the creator has a selection of quality / file size relationships.
MOV
MOV is another multimedia format, this time developed by Apple, and a proprietary container, and is compatible with various Windows and Apple systems. It offers several similar MP4s, with Quicktime and its ancestral features, but has less general support and lacks compatibility with many popular devices.
FLV
FLV stands for Flash Video and it is a proprietary format for distributing video through Adobe Flash Player, and it has become very popular when it comes to streaming video on the web. YouTube, Hulu, and many others have used FLV for streaming media, although this popularity is starting to decline with the advent of HTML5.
With Adobe’s exit from the mobile phone market in 2012, there are compatibility issues for FLV files on a wide range of devices such as Windows and Mac desktop apps available, issues with mobile devices mean there is a maximum users compatibility should look elsewhere.
WMV
WMV stands for Windows Media Video, which Microsoft created and is a format that was originally designed for streaming media, but has found acceptance in a wide range of applications, including Blu-Ray physics.
Its main characteristics are file size, maintaining good quality, and the ability to accept several different codecs depending on your individual situation.
It offers quite wide compatibility, especially as you can imagine with Windows products, although Apple systems require a plug-in for QuickTime, and many players will not play files natively, causing problems for use on many mobile devices.
