I have not found a list of the codecs, pixel formats, bitrates, and resolutions supported by NVENC on this card, but it should be able to encode simple H264 videos at the very least. My hardware is a Lenovo Thinkpad P40 Yoga with a NVidia Quadro M500M (GM108GLM) which is supposed to have PureVideo HD 6 (VP6).

I'm trying to get hardware encoding working on ffmpeg.
