Playback of a QuickTime file made in Keynote

    Hello
    A few days ago I started wondering about converting Keynote presentations so they could be played using Max/Jitter. I exported a simple presentation to a video file as a test. Now when this is played back in QuickTime (7 or X) it does a build, and then waits for a mouse click until the next build occurs. So effectively you can run it just like a normal presentation, even though it's actually a video.
    However when I open up the file with Jitter (jit.qt.movie), it doesn't pause at the appropriate points. Any ideas why/if this is possible?
    I have zipped up a small version of the file and attached it to the post. Below is the test patch I've been using to play it.
    Many thanks

      OK I've looked into this a little bit more and come across 2 things that might help a bit. The video is using a sprite track to control the playback. After poking around the jit.qt.movie, it does appear this track is seen and enabled.
      Then I had a quick play in Quartz Composer. Initially it did exactly the same as Jitter, until I found a checkbox for Asynchronous Mode. Checking this makes the movie play a single build at a time. The help info says that it makes the movie play ignoring the QC timebase.
      Can anyone help any further with this new information? So far I have managed to use Syphon to grab the video from QC into Jitter, but I really would like to play it directly in Jitter if that's possible.
      Thanks again
