Video output Nvidia H264 - > Cannot set up encoder error.

[dannnn222]

Hello. I've been using Mpeg4 AVC for a while now, and it's taking me all night and most of the day to render a 45-minute movie to 4K. A friend of mine's Nvidia H264 option significantly reduces the video conversion time. However, I'm getting this error. Could this be a problem with a faulty graphics card? I struggled with installing the drivers for a long time, and at one point, they weren't visible in Device Manager. Now they are. However, I keep getting the same error. What could be causing this?




My graphic is Nvidia Geforce GTX 660 2GB.
CPU I5 3550S
16GB RAM DDR3
