Hi Kevin,
I'm new to this issue. MacPro6,1 with dual FirePro D700s running Premiere Pro CC on 10.10.1 (current Yosemite.) No problems working on ProRes only projects for the last 6 months (since I bought the new MacPro and switched to Premiere) but now on my first Premiere project using R3D footage and all of a sudden all my h264 renders are full of these colored lines - whether I go to Media Encoder or Export direct (it's even happened within a sequence render.) Was outputting ProRes and then converting the ProRes output to H264 with some success but now am getting lines in my ProRes outputs sometimes as well. Only solution so far has been turning off OpenCL in Media Encoder (which is not a sustainable practice for my workflow.)
Please help?
Thanks,
John
