Thanks for the help and explanation! I can tell the encoding runs now,
tried with the following command:
$ ffmpeg -i perspective.mp4 -c:v h264_nvenc -profile:v high -preset:v fast
perspective_out.mp4

but the output image/video coloring really weird. from a normal coloring
it's going to be weird mixture of green,red "ghosty" image.
The input file details are:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'perspective.mp4':

Any idea?

Something is not right here. In your example command line do you call the output file "prespective_out.mp4" but in the details below is it called "output.mp4". The original file also shows to have a frame rate of 24.94 fps, but "output.mp4" is reported to have 29.97 fps, and you didn't perform and frame rate conversion on the command line.

Can you double check this, please?
