Evan,
What type of visual manipulation are you doing? If you are doing
something that only changes how the movie is displayed, you may want
to use Core Video/Core Image to achieve the effect in realtime.
Otherwise, the most obvious method (to me) to speed things up is by
manipulating the individual media samples yourself. It's not
difficult, see the Videoprocessing sample code.
later,
douglas

thanks for the suggestion- never used shark before.
It sat on h.264 decompression for most of the time, so I converted
the video
to DV and it took 2x the duration of the clip. Much better, but not
spectacular either.
