What is the best, free way to encode video for the new HTML5 video in browsers.  I want to encode video in WebM, H264 and Ogg.I have looked at FFMPeg and it seems to be able to do it all but the commands to do it with good quality can be fairly cryptic.Does anyone know of any good free tools that can do 2 pass encoding of video in each of these formats, or how to get FFMPeg to do task?
