I just bought a MacBook Pro in order to start doing some video editing and am so frustrated that none of my HDV 1080i videos from my Canon XH A1 HD Camcorder are working. My DP digitized the files to an external hard drive and are saved as quicktime files (I'm new to a mac and for some reason can't see file extensions, only the fact that it says: "Kind: QuickTime Movie", so I assume it's a QT file). More information about the files are: Codecs: HDV 1080i60 Integer (Little Endian), Timecode. I can preview the file and open the file in all of the following: QT, iTunes, Final Cut Express and it does the same in all of them - you can hear the audio, but the screen is black for video. I purchased QT Pro because I read in one forum that it had the codec necessary to show video... but that didn't work. Can anyone help? I'm so incredibly frustrated with this right now! Thanks in advance.
