I have a video with transparent background in presentation, which works perfectly in powerpoint & ppt slideshow mode.
When I use iSpring pro to create flash version, the video insert plays, but with solid black background.
I've tried remaking the video with alternative modes of alpha, (as premultiplied with black, white and none), and tried doing this with both AVI and MOV files.
All work perfectly in powerpoint, none work in iSpring flash conversion.

Can't iSpring recognise alpha channel in videos?
If it can, what do I need to do to make the flash include the video transparency?

Thanks in advance for any help
