Hello! I think it's an ideologic question, but I would choose VP8 and make a preview with speed=2 and the end-rendering with speed=0. For quality rate you have to try, because it also depends on your input data (Maybe start with 6 for the "ugly" and go down to "3.5" for the nice one?). But also Theora would be good enough for preview. I just can recommend the use of Matroska (MKV) and Vorbis. Greets, Kai
