How to save PyPlot figures to video file in Julia?

I want to do something like the following using a loop and PyPlot to plot in figure windows. My question is how to save the figure windows to a movie file within the loop?

using PyPlot

for k=1:5
  pcolormesh(rand(10,10)) 
  if k==1; colorbar(); end
  # save figure window to movie file here??
  sleep(.5)
end

This is possible by directly using the animation submodule of matplotlib (the underlying Python library that PyPlot.jl wraps). However, it is painful; see e.g. the following notebook (in Spanish):

The simplest way, however, seems to be using Plots.jl:
