I came across some VERY important/sentimental clips of my grandchildren and I when they were very young. An example of the file name is IMG_0311.mov. I am 100% positive they are video as I remember them distinctly. They were shot on an iphone (5 I think). When I open them on my imac desktop, it immediately opens a convert window. When I hit play it's only one frame long. I tried to convert with compressor, toast and tried importing directly into fcpx. Any help is greatly apprieciated.
