I haven't used any higher-end products to do this, but the time it
takes, using QT Player Pro, to convert a single track 25 second movie
into a flash .flv file of the same resolution is about 10 minutes or
more on a dual-G5 2 Ghz??? Both CPU's show over 90% load.
Sheesh. Even allowing that it is currently in H.264 format, that seems
rather excessive...
