Was attempting to export a 20 minute project from Premiere Pro, 1080p60, and was getting thrown back with nearly 2 hour export times. Played around with a few settings after a wealth of Googling, but nothing worked.
I then re-created the project in Davinci Resolve, exactly, and it's exported in less than 5 minutes.
Is there perhaps hardware incompatabilities?
I'm running a Ryzen 7 3700X, RTX 3070, and 16GB RAM. Windows 10.
Software only rendering can work but you are not using your hardware to it's full capacity. I see problems with the RTX 3000 series GPUs and AMD CPUs all the time. A BIOS update and driver update might help.
