Actually, I'm planning two MKV versions, the main one with 15000Kbps BD compatible stream and lossless audio and then another, cropped to 1280x542 at a much lower bitrate with the same audio options as the AVCHD for those, who want a more compact MKV version of around 5GB (it's preferable to people making their own smaller encodes with crappy settings from an already re-compressed source) - I could technically already release the smaller MKV now but I don't want people thinking it's the main MKV release.
