Hello, I can't seem to find anyone with this issue via net. I imported my 1080p60fps GP H3 Black footage into GP Studio 2.0 I then convert with fisheye fix and upped the quality to go to external hard drive on my 2010 MBP Mavericks. It will not play the .mov files GP Studio sent out without a conversion? I then convert and it plays but then wants to save the converted file. What am I doing wrong? I updated to Mavericks a day ago and I think that may be the issue but no one is saying anything on the net about it. Please help. Thank you.
