The globbing will probably order your files alphabetically, making
res-1*.png come before res-2.png. resulting in incorrect order.

I suggest:
$ ffmpeg -framerate 5 -i 'res-%d.png' -start_number 5 -c:v libx264 output.mp4
(Untested. Perhaps you need a different "-pattern_type" than glob.)

The numbers must still be sequential though.
