import video with alpha background

I have shot our learning host on green screen, keyed out the background in adobe premier cc and rendered a Quicktime file that imports into all my other apps with the alpha or transparent background fine but when I bring the same file into storyboard it comes in with the black background. Any clues or tips when it comes to importing video with transparent backgrounds? You can see this in the attached screen capture.

 

Thanks
