Converting vertical video to landscape

Hi,

Is there any quick tool to convert vertical iphone videos to horizontal videos by filling the black side bars with a blurred zoom-ed in sample of the movie, in the 'quick' mode of Premiere Elements?

I know that you can do this manuallyby using the 'Expert' mode, running two copies of each movie on parallel tracks and zooming in/blurring the second track but this seems very long winded when you have multiple clips to edit (d'oh - rookie error for years in filming iphone clips in portrait orientation!) I just wondered if there was a tool where I could just push one button on the movie and it would convert it, ideally staying in the 'quick' mode as I'm a newbie?
