What version of Premiere Elements are you using and on what computer operating system (including 32 or 64 bit)?
How are transferring the iPhone .mov from the iPhone to the computer and Premiere Elements?
What are the properties of this iPhone 4 .mov file....are you working with 720p (1280 x 720 @ 30 progressive frames per second)?
Do you have the latest version of QuickTime installed on your computer with Premiere Elements?
Let us start me and then decide what next.
Version 11 of Premiere Elements and my operating system is 64 bit. I've connected my iPhone to my laptop and dragged them into 'my videos', which is what I have been previously doing with all the other videos, and, they have worked fine.
I'm not sure what the properties are, I'm not that technical..
As far as I know, would an earleir version of QuickTime change things?
