Hi,
create pictures for each frame [1:N] ... (lets say pic_n.png)
then
mencoder mf://*.png -mf w=200:h=150:fps=25:type=png -ovc copy -oac copy -o
out.avi
now you should have a "out.avi"
Best

Assuming avconv or ffmpeg is available on your system, you can open a pipe
to it:
pipe, process = writesto(`avconv -y -f rawvideo -pix_fmt gray -s 100x100
-r 30 -i - -an -c:v libx264 -pix_fmt yuv420p movie.mp4`)
The options are detailed in the docs; -s is the movie size and -r is the
frame rat

You could use the animation interface of Matplotlib from PyPlot.
I looked into PyPlot, but it seems that animation doesn't work in IJulia?
The pyplot gui command didn't work for me (and pyplot doesn't work from
the command line). Maybe I just need to update my matplotlib.

Perhaps you are using a Mac, and don't have Matplotlib with a working Qt
graphics bac
Another possibilty would be to directly call the ffmpeg C interface, which
is quite well documented. Otherwise, if you want to use matplotlib, did you
have a look at this issue: https://github.com/JuliaLang/IJulia.jl/issues/107
