Despite lacking a Help file, KMPlayer is one of the most powerful freeware video players we've seen. It includes a vast array of video- and audio-capturing options, as well as skins, a plethora of playback controls and tweaks, and broad DVD support.
You'll have to learn the ropes yourself, perhaps a hindrance to newcomers. But if you're familiar with where things ought to be in programs, and willing to patiently wait for mouse-over labels to pop up and then click on them for the actual menus, KMPlayer has the potential to be immensely rewarding. It supports all major file formats, and all of the minor and obscure ones we tested. It did have problems with the RealPlayer 11's video capture IVR format, but not much else.
Advanced options include frame capture and a frame-forward feature, which is actually a fractional Play button, but the difference is negligible. The Pause button is a fast responder, too. Combined with streaming TV and HDTV compatibility, playlists, and the ability to select which codec is used on a video-by-video basis, and you get a media player that demands attention.
The KMPlayer is all-in-one media player covering various formats such as VCD, DVD, AVI, MKV, Ogg, OGM, 3GP, MPEG-1/2/4, WMV, RealMedia, QuickTime etc. It has an extra feature to play Incomplete/Damaged AVI file, Locked Media Files while downloading or sharing, Compressed Audio Album (zip, rar) and so on. It handles a wide range of subtitles and allows you to capture audio, video, and screenshots in many ways. The player provides both internal and external filters with a fully controlled environment without grappling with DirectShow merit system. The player can set multifarious audio and video effects, control playback speed and octave, select parts of a video as favorites, do a powerful A-B repeat, remap the keys of remote interface for HTPC including overlay screen controls, change a skin dynamically depending on a media type playing, and many more. It is completely customizable thanks to a wide selection of skins and color schemes, and configuration options are extensive.
