You entered 

> ffmpeg -y -hwaccel cuvid -c:v h264_cuvid -surfaces 8 -i "%_filepath%" -framerate ntsc -r 30 -vsync 2 -filter:v "minterpolate='mi_mode=blend:fps=120'" -c:v h264_nvenc -preset:v llhq -profile:v high -b:v 68M -bufsize 2M -map_metadata -1 -acodec copy -f mp4 "E:\Encoded-AS-%_filename%.mp4"
