I don't have the time or interest for anything fancy, just basic transcoding between formats, preserving as much of the quality of the original as possible. And shouldn't there be a simple switch or option that does pretty much that, i.e., "change the format, but keep the size and quality as close as possible to the original"? And why on earth is the default behavior to multiply the size by a factor of four just to retain the same quality? Is mp4 really such an inferior format to flv that this is required to retain the level of quality? Apologies in advance if these are naive questions, but I know little about this, and transcoding seems to be a sufficiently complex and arcane subject that simple web searching will only take one so far.
