MediaCoder

Hi there.
First off all thanks for that software.
some informations First
Mediacoder Version 0.8.42 Build 5822 X64
Graphic card Gforce gt 630M ( gpu GF108)
Windows7 64Bits
Now the problem
X264 with CUDA : ok, fast like i want (GPU used at 95% from GPUZ information )
X264 with Nvenc : Fail ( seems my card not able to use NVENC)
But the thing is, i'd like to use X265 with Cuda but i got : Video Format not supported by encoder.
it seem i'll never be able to encode in X265 with cuda card :-

HI, i have the same issue , i have a GTX 650 Ninja card which i believe supports H265.
I do not know the interface very very well so i might not be selecting the correct check boxes and maybe missing stuff.
Please can somebody assist ?
