The codec used was uncompressed 8-bit out of FCP 6. I have FCP X on my machine. But I mean I literally can’t see the file structure on the external drive. I have AVID files on my iMac and no AVID software and while I can’t open the files I can see the files listed –that they are there. I am confounded because I can’t see the .mov movies made on another iMac much less play them.
