what is the difference between compressing an edited video, for web upload, on Roxio Buzz (full version) versus Sorenson Squeeze 5 (Windows), please?

both seem to offer a range of MPEG formats, and Buzz is also an editor.

is it that Sorenson will compress to a smaller MB file size, whilst yielding a finer quality video?



ps. i also use Pinnacle 9 (av/dv) edit software, but the choice of web format files is very limited
