Multimedia Authoring - Quicktime Dead?

Qscript is what drove me to Revolution. ;-)

LiveStage is an incredibly powerful tool, but the learning curve  
makes Rev look like child's play. And Apple's track record recently  
with breaking things in each successive release of QuickTime doesn't  
help.

Anyway, having worked extensively with Keynote (v3 is by far the  
best), a few notes:

When you export a presentation to a QT movie, you will be re-encoding  
any embedded movies, so it tends to be a good idea to use high- 
quality originals. It's also a good idea to export at the same frames  
per second as the majority of your movies. Being based in the UK, I  
just stick with 25fps for everything in case it ends up on a PAL DVD.

With QT exports, pretty well ALL interactivity is retained, including  
URL links. BUT - when using hyperlinks to go from one slide to  
another out of sequence there will be issues with transitions, so  
it's best to leave them out, or do cheat and go to one slide earlier  
and use an automatic transition. Gets complicated, though. :-(

H264 and Sorenson Video 3 are by far the best codecs to use, although  
for high-res presentations h264 can get too heavy for the processor.
