Re: [Matplotlib-users] video without black bands

[Benjamin R. <ben...@ou...>]

In your options to mencoder, you are specifying the width/height as:

>>> 'type=png:w=9800:h=600:fps=0.6',

But your PNGs have size of 704x538 pixels. That's why you have black bars
on either side of your animation.

Cheers!
Ben Root
