Cannot play or import iPhone 4 videos in Aperture 3.3.2
When trying to import a video I shot on my iPhone 4 with the built-in camera app into Aperture, I just received the message "Unsupported video format". If I try to import the video as a file from the desktop, it does not even show up in the import dialogue.
Similarly, all iPhone 4 videos I have inside Aperture already don't play anymore. I can still see the thumbnail, but trying to open them will just bring up a grey screen - nothing else.
All videos play fine in QuickTime, I have verified they are the usual standard Apple Codec and none of the other threads here helped me.
Would anyone have any ideas?
iPhone 4, iOS 4.3.3
