On latest Adobe Premiere Pro CC, when trying to export a 1080p or lower quality h.264 video of a 4 minute length project that renders 25+ clips in parallel, for a sequence that is longer than a few seconds, I experience one of the following issues:
"Encoding" freezes and there is no usage of CPU and GPU. After cancelling, Adobe Premiere Pro no longer is able to render any frames within export window or renders black (GPU 1 state within Task Manager always stays on Copy)
Export simply fails with a failure to render a frame
Adobe Premiere Pro crashes with a Send Report window
Adobe Premiere Pro crashes without a report window
Tried removing all markers for the encoding freeze issue without.
