Comrades,
I have a PPT slide with a number of video clips.

There's a button for each clip which triggers the animation.  When the
button is pressed...

- There's an Fade entrance animation that's triggered by the button.
- There's a Play animation set to "After Previous"
- There's a Faded Zoom exit animation set to "After Previous".

The videos usually play perfectly.  But sometimes the last second ot two
gets cut off by the exit animation.  Am I doing something wrong?  It seems
to be pretty random - sometimes it's fine, sometimes not, and different
machines exhibit different behaviour.

I guess one option is just to extend the video clips a bit to take into
account the chopping.

Cheers,
Geoff
