 Don't forget about [https://trac.ffmpeg.org/wiki/HWAccelIntro/ HWAccel] too, e.g.: `-hwaccel auto -i input`

+If you have access to the Nvidia NvEnc hardware (ffmpeg -encoders shows h264_nvenc) then you can use ffmpeg -h encoder=h264_nvenc to see the specific options it provides.

+See https://trac.ffmpeg.org/wiki/HWAccelIntro#NVENC for troubleshooting tips

+Examples:

+Maximum speed
+ffmpeg -i INPUT_NAME -c:v h264_nvenc -preset p1 OUTPUT-NAME
