Here's the situation:
I am working with media that is ProRes 422 (HQ), 23.976, 1920 x 1080.
Audio is 16 bit 48k Hz
I have edited my sequence and round-tripped it to SpeedGrade already. I have an effect plug-in called Beauty Box on nearly every clip.
I am using Open CL playback.
Everything was copacetic. Out of the blue, I suddenly started having issues with the image flickering during playback. I wound up having to go back into Beauty Box settings on each clip and re-rendering them one at a time all the way down the timeline.
Anyway, the situation worsened when Premiere began to no longer "un-render" the effect on each clip. If I tried to alter the effect or turn it off, the video playback would just freeze (on that one clip).
I finally re-rendered the entire timeline to a new location. Of course, the flickering came back, so I have to once again render each clip individually.
Things got even worse tonight when I tried to start my fine audio pass. The same thing began to happen to the audio; playback would stutter and drop frames or finally stop altogether.
I looked at the event log and saw multiple instances of the following message:
OpenCL error: CL_EXEC_STATUS_ERROR_FOR_EVENTS_IN_WAIT_LIST
Hardware specifics follow:
Intel Core i7 8 core @ 3.20 GHz
24 GB installed RAM
Windows 7 Professional, Service pack 1, 64 bit
video cards : 2 X AMD Radeon HD 7900 (3 GB Ram)
Disk drives (all SATA):
1 TB Lacie 7200 RPM for original media
1 TB Western Digital Caviar Black 7200 for renders and previews
320GB Western Digital Caviar Blue system drive
Audio - RealTek HD audio (built-in to motherboard)
Saffire Pro 14
Any help would be greatly appreciated since at this point the work on this project has ground to a virtual standstill. If any additional info is needed for diagnosis, please let me know.
Wow, not a single suggestion? At this point, it looks like I am going to have to try to export the project to Avid since I am stuck dead in Adobe.
I'll update here if that solved the problem.
I suspect it's a video card issue, but I am not able to diagnose this myself and I don't really have the time to become an expert on video cards vs. PPCC2014.
