You can use mkvmergegui for muxing. It has a webm-checkbox in the "global" tab.
For audio encoding any vorbis encoder will do. You can find windows compiles at rarewares (http://www.rarewares.org).
For the video encoding there are ffmpeg builds that support VP8, but I don't know where to get them, sorry.
If you are looking for a all in one encoding tool I think you can use firefogg or one of the others listed on the WebM site (http://www.webmproject.org/tools/).

Hi xbox... I struggled for months with the same question and after trying A LOT of tools, the best way is to use ffmpeg...

First, you have to download a good build... I download mine (Windows) from here http://ffmpeg.zeranoe.com/builds/ (Choose Static builds preferably)

Then if you know how to use CLI applications, just use this or similar parameters...

ffmpeg -i [here goes your input file without the brackets] -vcodec libvpx -level 100 -vb 512k -ab 32 output.webm

And that should be it :)... One thing I've noticed is that ffmpeg has a lot of trouble to hit the desired bitrate on low-bitrate cases... But in any case, you get a great size/quality ratio anyway :)

What do you mean the proper Video & Audio format? Anyway, XMedia Recode produces WebM (and not only) files. Good, intuitive software.
