this page contains two fast stream quicktime movie clips, a video and an audio clip of 45secs duration, made separately in premiere with 'video' compression, at 2 fps, 5khz audio, with a combined data flow rate of about 9k/sec(3.5 video. 5.5 audio).
this was done to minimise load times.
the clips were then further processed in quicktime internet tool which makes the clips readable across platforms.
compare the next page which was the same movie made the same way in premiere but as one movie, video and audio.
