MKV is a common video file defined by Matroska Media (a new multimedia package format). MKV is different from both DivX, XviD or other videos encoding formats and MP3, Ogg or other audios which only provides these audios and videos with “cover portfolio” and “package format”. The biggest feature of MKV is that it could hold many types of encoded video, audio and subtitles flow, and even very closed streaming media like QuickTime and RealMedia. Actually, AVl, VOB, MPEG, RM also belong to a container format as MKV does, but their shortages of old structure or being not open enough leads to MKV's (the new multi-media packing format) birth.

WMA is Windows Media Audio. WMA is a new audio format developed by Microsoft well known as MP3. With a higher rate in files compression and better sound quality than the latter, even far beyond those of RA. 

To convert MKV to wma file, you may first install the latest Matroska mkv codec pack for the mkv splitter filter. But the video and audio stream can be encoded with any codecs, if the MKV converter does not preview the mkv file still, please install other video and audio decoder for the mkv file.

Download WMA Converter which can convert mkv to wma file. Select an mkv file, set the start time, the end time or audio encoding bitrate if needed. The bitrate is bigger, the file size is bigger, the audio quality is higher, and vice versa. Click the Convert button to convert mkv to wma.


M4V is mpeg-4 video. mp4 video sometime use the file extension or *.mp4v. IPod or iTune uses this kind of format. To convert m4v to wma please install m4v codec. If the file is protected or encrypted, the conversion will fail.
