...doing training video...restricted to stills and narration...lots of narration and text....using track motion on stills and nifty transitions but these are great for 1 to 2 minutes segments but most segments are 8 to 10 minutes long and the stills are limited ...got music too...need to keep viewer interested all the way through with "stuff" happening on the screen...ran out of ideas...any suggestions would be VERY much appreciated...
