To use this method you’ll need mencoder.exe which is part of the mplayer distribution. Download it here.

The bat file with the command can be downloaded here.

USAGE:  mencode_from_wmv.bat input_file.wmv

This will produce avi. If you want to have mkv format use mmg.exe from mkvtoolnix (here).

This batch works in 2 passes:

1 pass:

mencoder input_file.wmv -ofps 30000/1001 -ovc x264 -x264encopts subq=1:frameref=1:pass=1:threads=2 -nosound -o input_file.wmv.x264.avi

-ofps is necessary due to wrong recognition of framerate in wmv

2 pass:
