Right. Matroska is the container format and mkv is the extension, not the 
video format. Matroska containers can contain video in a number of different 
formats e.g. mpeg4, h264, avi etc. The -f switch specifies the video stream 
format, not the container format. The container format is determined 
automatically from the file extension.

At least I think that's how it works... ;-)
