so dovetailing into my card reader question does anybody have a link or know where to find a comparison chart that shows record times against the various formats and encoding schemes offered by the newer sony cameras. I am mid purchase on my PMW-400 and trying to figure out which cards to buy and how many of them. The manual does not seem to have a chart which would be useful in these kinds of things. In particular I want to know how fast 10 bit 422 50Mbps video will chew up a card.
