4K HEVC = extremely long rendering time, 5min video takes 3 hrs in quality mode, 1hr in speed mode.

Rendering 5 minutes of 4K XAVC-S 264 MP4 to 4K HEVC 265 will take over 1 hour, setting the speed control to Quality instead of speed will triple that time to 3 hours !!!

Hardware acceleration will make NO difference. I use Nvideo driver 314.07. Installing 337.88 will grey out the HA box. I am using a GT640 board with 2GB of memory.

Rendering is done by i7 920 2.67Ghz CPU only, running 100% on all 8 cylinders.

Rendering the same XAVC-S 4K video file to 4 K MP4 264 takes 20 minutes.

Is this the price I have to pay for HEVC ?

The nVidia encoder doesn't work for h265, it's only h264 @ 1080p capable.
Newer Maxwell chips (750, 970, 980) supposedly can do h264 up to 4k, but I don't know if PD can use that feature.
AMD hardware doesn't support h265 either.

I suspected as much, in time there will be something.

I have, for example, a 90 min 4K XAVC-S video of our April China trip. I will render it to 4K HEVC in November when we are going on a 7 day cruise.

The button "turn off computer when finished" now has some significance, it will hopefully turn off the computer after a successful HIQ mode render about 4-5 days after we left. !!!

I would be anxious to get some rendering times for 4K 264 to 4K 265 conversions.

I never turn off my PC. But maybe if I was out for a whole week I would.

currently, no graphics cards as far as I'm aware, doesn't support hardware encoding of H.265. As for 4K hardware rendering, the Nvidia 750 does only 1080p, while Intel Quick Sync can handle 4K H.264 perfectly Main Machine: Jetway NF9G-QM77, Intel i7-3610QM, Nvidia Geforce GTX 1060 3GB, 128gb SSD, Windows 10 Pro
Secondary Machine: Lenovo Y510p, Intel i7-4700MQ 2.4Ghz, 2x nVidia GT750M, 500GB SSHD, Windows 10 Education

It is not only about support using the graphic card hardware encoders. I think that's a dead end, no matter how fast they are.

It's about using video card computing capabilities like CUDA or OpenCL to process the encoding. Is like programming for a CPU, using C++ tools and libraries adapted for GPU.
