I have a timeline of RED footage and it all works as it should until I open up the RedCineX plug in and change something (like the gamma space for instance). Then when I come back out the preview window hangs and ultimately goes black and won't reload. This doesn't happen in AE 2014 or Premiere Pro 2015.
I am running the latest build of After Effects. Windows 8x64 and NVIDIA GTX 860M.
All other RED files in the timeline are frozen as well. Non-RED files still work. When I scrub over any RED files in the timeline, the preview window goes black. The thumbnails for the RED files in the Project window are black. I can still open the RED Plug In and see the footage and make changes.
Again, this issue does not occur until I make a change from within the plug in. It runs normally until I go into the plug in and change anything. Then it's gone.
