In my effort to save hard drive space, I've transcoded some AIC stuff to H.264 using mpeg streamclip, and am trying difference settings. Using two different quality settings, I'm getting a 2.2gig file and a 200meg file, and then going back to look at the differences in quicktime. Here's the thing: I can't see one. Finder says that the data rates are 50kps vs 7kps. (These number are all approximate. Except the .264.) Am I as inept a videophile as an audiophile? (MP3s sound as good to me as cassettes and stuff.) The text looks as legible in one as another. Some possibly relevant things are that these are screen captures from World of Warcraft on a 25x14 screen scaled down to 12x7 to begin with, and I'm watching all of this stuff on my computer. Also, anything I do with these is destined for YouTube.
