The same thing goes for the quality: libx264 defaults to crf=23, I
don't know about nvenc. Furthermore, encoders can trade off quality

Different encoders can have different defaults. It appears that nvenc
defaults to "Main",

Hi Carl,
Should I rerun the ffmprg command without the "loglevel quiet" and
report the output?
Please suggest. The input file is rather large, and ffmpeg console
output is likely to be very long.
thanks,

ffmpeg has been built
with both libx264 and nvenc codecs enabled.
ffmpeg when run using nvenc codec creates a file that is almost double
the size of input
mp4 file and bitrate almost double the size of input file.
