What you need is a DirectShow splitter to sparse mkv files. I’m not familiar with what the K-Lite codec pack bundles or not, but you might want to look at http://www.matroska.org/downloads/windows.html. Look in the section where it says filters. If one doesn’t work, try another. If they all fail, my suggestion would be to scroll down and use an editor instead to convert to an intermediate format (AVI, MPEG, whatever) then feed that into movie maker.
but i did convert mkv to avi from mediacoder. but wmm still can’t import it it says this.By the way I have k-lite codecs mega pack
The required codec was not downloaded automatically because the Download codecs automatically check box is not selected in the Options dialog box.
Windows movie maker can only accept video files in format AVI, WMV, MPEG, etc. So, if you want to import your MKV files to Windows Movie Maker, it is better for you to convert the MKV to WMV or AVI format enable in Windows Movie Maker first. If you dont have a suitable video encoder , go to http://www.tucows.com/preview/515178 , I ever used this video conversion tool to succeed in converting MKV to WMV, fast and losslessly...
Why are people referring to wrappers as formats?
How do you expect to clear anything up like that?
A wrapper such as avi or mkv is like a format for holding other formats; it can hold multiple streams that can themselves be in a variety of video and audio formats.
A tool that converts from mkv to avi does not necessarily alter the format of the video stream. This is why converting to avi doesn’t always work, even though it is a listed filetype that Movie Maker can use.
You actually need to transcode the video stream to a nice standard, old but possibly dumb format, like mpeg2. Never mind file size; you’re editing.
