KMPlayer is a well-known multimedia player that can play movies, music and more. KMPlayer supports various codecs and high-definition services. You can also add external codecs. For the non-techy, this means it can decode various video formats such as 3D, 4K, Ultra High Definition, and even extend the video player’s compatibility if you need it. You can also enjoy your movies with crystal clear image quality on DVD and Blu-ray. A video player’s flexibility to differing file formats is one of the most important features to look for, and KMPlayer scores highly on this. It supports many file formats, including WMV, MKV, OGM, 3GP, FLV, and MOV.
