Because of Apples failure to implement the conversion of the 3D transitions in Keynote '08 to SWF and their subsequent admission of defeat by dropping the export to flash option in '09, I was looking for a way to convert QT to SWF.
VideoVangelist can do this but the quality leaves a lot to be desired in comparison with Vertical Moon's Video2SWF. This latter application is not perfect either and maybe I'm expecting too much!
