Low quality animations matplotlib after saving

I have made a simulation in julia using matplotlib as a visual tool. When I use the command to display the animation

anim = animation.FuncAnimation(fig, animate, frames=int(time[end]*10), interval=20, blit=false, repeat = false)

all is fine and the animation looks nice. However when I try to save it using 

mywriter = animation.MencoderWriter()

anim[:save]("/home/maquinadt/Documentos/gas.mp4", writer = mywriter)

the video is saved with a very low quality (I mean it looks very slow compared with the "live" version).

I have played with the fps keyword of save but the result is the same.

Any ideas?

Did you try adjusting the bitrate as well? Take a look at the docstrings for the MencoderWriter:

http://matplotlib.org/api/animation_api.html#matplotlib.animation.MencoderWriter

You should also be able to pass arguments to mencoder through the extra_args keyword argument. Finally, I think the ffmpeg writer has nicer defaults, so you could also try that if you have ffmpeg installed.
