Prevent Resolution changing when saving animation?
 

I am trying to create an animation with Paraview with a reasonably large mesh (2 million elements) and a number of calculators in PNG format. During the process of creating the animation there appears to be some bug that causes the animation to stall and the output frames simply repeat (so for example I am trying to produce 50 frames. The first 12 are correct, but frames 13-50 are a repetition of frame 12). I am trying to restart the generation of the animation from the last good frame (in my example frame 13) and match the resolution, but paraview is driving me psychotic by forcing a resolution change.

for example

"The requested resolution has been changed from (2496, 1401) to (2469, 1400) to match format specifications."

How do I preserve my sanity and prevent paraview for d**king around with my requested resolution?
