The syntax looks legit. I see you are not specifying a profile. So 
perhaps the native resolution of clip.mp4 is low? I would try specifying 
a profile. Or specify the size in terms of percent instead of absolute size.

In my opinion, it is easier to learn the syntax from a GUI application 
like KDENLIVE or Shotcut (both have filters to use the dynamictext 
filter) and then look at the resulting XML to see what parameters work 
for you.
