Hello, I just registered here as a last resort because I cannot seem to figure this out.

I recorded a video using my iPhone4, and am trying to upload it (.mov format) to YouTube, but YouTube keeps saying its an invalid file format. But it lists .mov as one of the accepted formats.

What is going on? Do I have to convert it? I would think this should be easy, but I've spent over an hour downloading video converters that don't work, and trying to figure this out, and I am very frustrated now. I'm running a Mac, if that helps.

Please help, Apple experts! Thanks in advance!
