Well, in honesty, you said the name would be res_5.png, not
res_05.png. That's a difference for the "%d" operator. You need to
force min two digits with filling zeros: "%02d".

Yes. In that case, you would place the list of images in a text file:
and use the concat demuxer:
$ ffmpeg -r 5 -f concat -i in.txt -c:v libx264 output.mp4
(Should work. ;-) I get peculiar DTS warnings though, must investigate.)
