I have Rigaya's NVEnc installed in Program Files but XMedia Recode does not see it and wonder where to install NVEnc so it shows up in XMedia Recode ?

Also, I'm using a LUT for conversion of HDR to SDR in XMedia Recode ('Filter/Preview' Tab > Add Filter > 3D LUT) but it mainly uses the CPU at around 40% and so takes around 7 hours to complete as the Nvidia NVENC GPU use is 10%. Is there any way to get XMedia Recode to mainly use the GPU to do the HDR to SDR conversion ?

Thanks.
