The K-Lite Codec Pack package is a collection of VFW / ACM codecs, DirectShow filters (including LAV and ffdshow) and many other tools enabling playback of various audio and video file formats. Thanks to it, we will be able to watch almost every movie on the computer, including those with subtitles.
Full version adds full support for more video and audio formats, also has support for file encoding. As a result, the K-Lite Codec Pack Full is designed mainly for advanced users and people who create multimedia. The package has, like the Standard version, an audio / video player called Media Player Classic, supporting a number of multimedia formats and based on the DirectShow platform.
When using the Full version, we are able to compress movies to selected formats, however, nothing prevents us from using it only to play files. Additional features are also important: Codec Tweak Tool that allows you to set individual codecs, as well as MediaInfo Lite informing us about the parameters of multimedia files (eg codecs, bitrates used).
