You don't say how long these movies that you want to be 250K are, but you
are probably asking the impossible. The best quicktime compression
currently avilable is the Sorenson codec, which is only available through
QuickTime 3 (viewers would have to have QT3 or QT3 for Windows installed in
order to view it). I just converted a full screen movie that was 397MB to
a quarter screen compressed movie that became 7.1MB. This is a pretty
remarkable rate of compression, given that the final quality is really
quite good. However, it's still big for a web document. Such is life -
the net still ain't very good as a means of distributing video unless you
have a fast connection.
