I'm trying different export scenarios for an HD XDCAM EX 1080i (HQ) 25fps sequence.
If I use the default PAL DV AVI or OP1a XDCAM EX 35mbps preset with CUDA accelerated MPE(Mercury playback engine) the CPU usage on export is 80%+ and the export is very fast.
If I use the default OP1a SD presets with CUDA accelerated MPE the export speed is very slow and CPU usage is below 10%.
If I use any other "custom" SD or HD AVI codec setting CPU usage on exports falls below 10% with CUDA accelerated MPE.
CPU usage stays at below 75% with software only rendering. Export with software only MPE is a bit slower than with hardware accelerated MPE with default presets.
Is there a particular reason for CPU usage to fall with custom settings?
Premiere is 2017.1.2
Media Encoder is 2017.1.2
The system is Lenovo Thinkpad W520
CPU: Intel Core i7 2760QM
GPU: Quadro 2000M
