I'm having an issue with my encoding time from an specific video and I have found out that an specific Lumetry layer was the cause of it.
With it, premiere takes 2h15 to export a H.264 3gb file, and without it, 10 min.
This layer has a LUT, basic correction adn curves, and I've tested without each one to see if there was a single guilty, but the reduction each one caused was insignificant in relation to the total time.
Sorry about this. Is Export Settings Dialog Box > Video Tab > Hardware Encoding available? Is the Project Settings > General > Mercury Playback Engine enabled for GPU acceleration? We need to know those things and your full system specs. Need help finding those settings? Let us know.
