There is not a way to output in any "video" format. There are
a number of products you can use to do file conversions, but in 99%
of the products, the conversion is going the other way, from video
to Flash. Were you aware when you bought it or downloaded the trial
that Captivate's output
was SWF? Seems something too big to miss. Anyway, converting
a Captivate SWF to one of the old video formats would - in most
cases - be counterproductive.
Best of luck to you if you choose to leave the product.
