This command line makes no sense:
-vcodec copy tells FFmpeg not to decode and (re-) encode
video but to remux the video stream. You cannot change
the resolution when remuxing but that is what you
request with -s.
When asking for help here, always post your command line
together with the complete, uncut console output.
(And please don't forget not to top-post.)
