Unrelated: -framerate 59.9 is most likely wrong, should be 60000/1001 > frame= 74 fps= 10 q=-0.0 Lsize=N/A time=00:00:01.43 bitrate=N/A speed=0.202x The encoder is (far!) too slow, you could try with -vcodec ffv1, but you most likely will have to either use a significantly more expensive CPU, or a lower resolution or a lower frame rate. If you have sufficiently fast disks, you can try to save rawvideo (and re-encode later). [...] > Any help would be appreciated. 1080p capture right to rawvideo is perfect. I > would like to use NVENC in lossless mode if anyone has experience with that. Is there really a hardware encoder that supports lossless encoding? If yes, why did you use software encoding at all above?
