I've used Keynote and it works well (have only tried version 1). My
only gripe about it is writing text with superscript/subscript isn't
easy like it is in PPT.
There is a well documented bug in Powerpoint 2004 for mac regarding
movie playback performance which seems to be the problem. There are
hundreds of posts on Microsoft's support forums. Actually when you
build the slide in PPT 2004 in edit mode the preview of the movie plays
fine but not in presentation mode!!! If anyone has found a work round
let me know!
I've just made three movies of a simple rotation each one was saved
using Macpymol 0.98 beta 27s Save movie as quicktime (more options)
drop down. I selected best quality for all three but tried 12, 15 and
24 fps. Powerpoint 2004 for Mac gives either a jerky, stop/start
rotation or (with a bit of fiddling of the "scale" settings) it gives a
reasonable rotation but the image breaks up during playback. All three
versions work well (an occaisional streaky line) in Powerpoint v.X and
work perfectly in Keynote - smooth rotation and no image breakup.
If you use a mac, use PPT v.X or Keynote!

Well, using MPEG encoding on a PC I've found that a normal 25fps
framerate
can involve too much data for PowerPoint to handle, thanks to some
idiotic "feature" used to scale movies in presentation mode. In the
past, I've been able to fix this occasionally using smaller movies, or
using a reduced framerate. I found that 20fps was quite reasonable and
the computer didn't choke. (Oddly, I was using lower compression and
the bitrate was actually higher with the slower movies!)
Personally, I've found MPEGs to be extremely portable and (to the
extent
that anything does) they work well in PowerPoint. You just need to
fiddle
with the compression and framerate settings to get something
high-quality
that won't hiccup in presentations. Either Windows Media or Quicktime
can produce better movies but I think this involves more advanced
codecs
and you lose quite a bit of portability. You should have the same
control
over compression ratio and framerate, though.
Has anyone used Keynote for anything like this, by the way?
