[Paraview] Save Animation option in ParaView 5.4.0 vs 5.3.0

[Van Moer, Mark W]

Hi Utkarsh, 

I missed this and just saw your GitLab comment. To answer your first question, I was on Linux, saving as PNG. But, you're correct, my issue was that ffmpeg accepts two -r flags, one for the input and one for the output and what I needed to do was set -r 1  and -r 30, respectively. 

Thanks,
Mark

Mark,

As  I was re-reading your email while working on issue #1792 [1] which affects the save animation dialog, I have a few questions: Are you saving the movie as AVI (and on what platform). If so doesn't changing "Frame Rate" have the same effect for avi? If you set your frame rate to 1 frame/second, doesn't that yeild exactly what you're looking for
-- each frame stays on for 1s with discrete jumps and no interpolation? Atleast on linux/mac where the FFMPEG writer is used, I can see that the frame rate of 1 fps works as expected. What am I missing?

Thanks,
Utkarsh
