I work at a company that has 7 MacPros all of them at sometime or another export those lines. I say at sometime or another because they are not consistently happening between all 7. We export with AME CC2014 using multiple codecs-- h.264, match source- high bitrate, and prores. We then use the AME CC to covert those match source files to .fv4 for our LCMS. The lines show up randomly between all machines and there seems to be no reason for any of them.
I've tried clearing all caches and preview render files that could be associated with the project as well as restarting our computers. The only thing that is guaranteed to work is turning off OpenCL. All our computers are running on either Yosemite or Mavericks (some upgraded and saw the lines, so we stopped upgrading). We are all running on PP CC 2014 the most up to date versions. My computer is running 10.10.1, MacPro late 2013, 3.5 Ghz 6 core Intel Xeon E5, 32 GB of ram, AMD FirePro D500.
We like many of the other people on this thread work on deadlines. These lines aren't going away, lots of people are having this problem, and your idea to have Apple check my hardware is a bit insane as I'd have to take 7 MacPros to the service center and stop work on all our projects-- about 200 videos.
I have been following this thread and trying every thing that's been mentioned and finally decided to chime in to say that 7 MacPros are all having the same problem so it's not just a few people.
