So, lately I've been using NVENC with a crf of 18, and the ultrafast preset. Most of the time this seems to be fine, but sometimes video's will just start glitching. This is usually the case with videos with AAC audio. So, I heard QuickSync is more reliable, but doesn't this run entirely on the CPU? I prefer encoding on the GPU, since it's stronger than my CPU.

 

Anyways, I'd like to know what settings I should use.

 

I don't really mind a little quality loss, just nothing too severe, but what I find most important is that every video plays back without any glitches, and that the encoding process is fast.

 

My specs:

 

8GB RAM

i5-4440 CPU

GTX 970 GPU

CRF18 is probably a little too much at the ultrrafast preset unless you have a really good GPU. Try CRF 21-22, that will relax the quality just a little and be kinder to the ultrafast preset. I actually run NVENC with CRF 20 @ Auto preset. on a nVidia GTX 1050Ti - No issue with the output and only a few secs to start playback with zero buffering - even over 4g @3.5mbps.
